to 8,000 Times Cheaper Thorium for Electricity and Desalination
Two billion people around the world still do not have electricity. . .
the world must consume more energy, not less"
~ H. Douglas Lightfoot
Converting the coal-burning power plants of poor countries to almost 8,000 times cheaper thorium electricity
Energy is
the master resource. Electricity is the highest form of energy.
Energy
Correlates with Prosperity. Prosperity Correlates with Fewer Children.
This is most important to those living
in developing countries.
We are a 10,000 Watt per person society. Mexico is a 2,000 Watt per person society. Bangladesh is a 214 Watt per person society. Now you understand why energy supply is more important to you than Global Warming. Global Warming is not going to go away and America will need lots of energy to survive Global Warming.
"How critical is cheap energy for developing countries? Bryce points out that Africa—a continent with 14 percent of the world's population—has developed only 3 percent of the world's electricity. Of the 15 countries in the world with the highest death rates, 14 of them are in Africa. Of the 22 countries with the highest infant mortality rates, 21 of them are in Africa. Many factors contribute to those high death rates, but a widespread availability of cheap energy would likely make life healthier for millions.
From "Gone with the Wind" - - Unreliables like solar power and
others can't fuel America's future. Say experts: Just do the math." - - Jamie Dean
"The International Energy Agency and World Coal Institute report a 10-year
increase in life expectancy for every tenfold increase in electrical power
availability. Of the world's approximately 6.8 billion people, only 2.6
billion have adequate electrical power." - - A.J.S. Spearing, Ph.D., P.E.

Living better electrically. Abundant cheap electricity attracts industry and business like an electro-magnet. The Niagara Falls area is an excellent example. As quickly as generators were added, industries that were heavy users of electricity, such as aluminum refining, built their factories there. Today, the combined Niagara Falls generators can produce up to 5,000 megaWatts.

Repowering Developing Countries
ECONOMIC: We are in the early twilight of fossil fuels. Things will only get worse as we run out. Like the cost of oil, the cost of coal has been steadily creeping up over the years ($30/ton, 1999, $117/ton 2009). Difficult for rich countries, a living hell for poor countries that have to import coal.
ENVIRONMENTAL: Boilers make over 60% of ALL Global Warming. The author has discovered that only 2% of the world's boilers are making 30% of ALL Global Warming CO2. These are the boilers we must take out immediately to blunt Global Warming. About half of them are in developing countries.
Uranium reactors are inadequate for the economic and environmental tasks above. The author knows of a simpler and safer reactor called a "Thorium Powered Converter Reactor" - designed by EBASCO for a power plant in 1972 but never built - that would make an excellent nuclear boiler for replacing the world's 7,000 largest coal burning boilers - about half of which are in developing countries. This reactor is especially well-suited for developing countries that are not "nuclear-ready". http://en.wikipedia.org/wiki/Developing_country
The intent of this project is to keep costs to an absolute minimum by CONVERTING existing coal burning power plants to thorium nuclear rather than building all new. This is an approach well-suited to fighting the coal cost crisis and Global Warming in developing countries.

The World Bank supports coal projects where it is the only option for the poor
The World Bank funds less than 1 percent of power plants around the globe. However, the World Bank Group does support coal power generation if it is the only way to get electricity to people who don’t have it. This was the case with a major project in South Africa in 2010, where the Bank provided financing to the only “super-critical” (i.e.: cleanest technology available) power plant on the African continent, to help South Africa after a blackout in 2008 that cut power to hospitals, schools and the country’s entire manufacturing base. The Bank Group’s policy is to support countries in such, but under strict criteria, which are:
1. there is a demonstrated developmental impact (e.g. improving overall energy security, reducing power shortage, or access for the poor)
2. there is assistance to identify and prepare low carbon projects
3. there has been optimization of energy sources by considering the possibility of meeting the country’s needs through energy efficiency and conservation
4. there has been full consideration of viable alternatives to the least-cost options (including environmental externalities), and when additional financing from donors for their incremental cost is not available
5. the project uses the best appropriate available technology, to allow for high efficiency and, therefore, lower GHG emissions intensity
In regions such as sub-Saharan Africa and countries such as India, where hundreds of millions of people have no electricity, getting access to energy is the predominant issue for them and for their governments.

The coal cost crisis
EXAMPLE: Morocco's coal crisis. (GDP = $9/day per person vs. U.S. = $130/day) Morocco had to close its only coal mine about 10 years ago and now has to import coal to power its electricity generating stations. Even with constant import tonnage, the coal burden has risen ($30/ton, 1999, $117/ton 2009) almost a half billion dollars over the last decade - a crushing, economically disruptive currency drain for an already poor country. Converting Morocco's coal boilers to 7,800 times cheaper thorium is a project that will greatly benefit the 36 million people of a developing country.
The global impact of 7,800 times cheaper electricity becomes apparent when you learn 85% (approx. 5.8 billion) of the world's population lives in developing countries.

Morocco's Jorf Lasfar, Units 5 and 6, is an excellent place to begin restarting thorium-fueled liquid reactors.
Using Oak Ridge National Laboratories 1962 1,000 mWe power station study, ORNL's 1965 to 1969 Molten Salt Reactor Experiment (MSRE), and the 1972 EBASCO report as templates, and the upcoming Units 5, 6, and Desalinator construction project at Morocco's Jorf Lasfar power station as the target project, the following technology gathering, integration, and application plan is suggested. See Thorium Fueled Nuclear Boiler page on this web site for details.
From Mitsui announcement:
"May 10, 2011
Mitsui & Co., Ltd. ("Mitsui", head office: Chiyoda-ku, Tokyo, President: Masami Iijima) announced today that a consortium consisting of Mitsui and Daewoo E&C ("Daewoo", head office: 57, Sinmunno 1-ga, Jongno-gu Seoul 110-713, Korea) entered into an engineering, procurement and construction (EPC) contract with Jorf Lasfar Energy Company 5&6 ("JLEC 5&6"), head office: El Jadida, Commune Moulay Abdellah, Route Régionale 301, PK 23, Centrale Thermique de Jorf Lasfar, Morocco) for the development of a 700MW coal-fired power plant in Morocco.
Mitsui and Daewoo will construct two new units, each with a gross capacity of 350MW, at the existing Jorf Lasfar power plant site (currently four units each generating 350MW) near El Jadida, as well as installing the first flue-gas desulfurization (*1) system in a Moroccan power plant. The site office was completed in April 2011 and accordingly the site works has been started. Commercial operation of Unit 5 is expected to commence in December 2013 and that of Unit 6 is expected to commence in April 2014. The contract is valued at approximately 1.1 billion United States Dollars, making it one of the largest power plant EPC projects ever awarded to a Japanese company in North Africa."
Molten Salt Reactor Development Plan additions to existing Mitsui design: The construction of Units 5 and 6 would proceed as contracted.
The first additional feature would be the addition of flanges in the steam and feedwater lines to accommodate selector valves to enable running the turbines from either the coal boiler or the Molten Salt reactor.
A second additional feature would be the reservation of space along and on either side of the new smokestack axis to accommodate the two steam generator houses, the secondary salt heat exchanger house and the temporary barge access slip on the stack's axis to the Atlantic Ocean.
A third additional feature is reservation of space in the control rooms to accommodate the Molten Salt reactor's control mechanisms.
An extensive variables data gathering system (details to be determined) with continual real-time offsite telemetry and control room video and voice line logging capabilities is also in order.
Such an arrangement should cover all developmental and operational contingencies and also provide the most solid data possible for operational monitoring and analysis by the IAEA, the various engineering offices, involved academia, and of course, involved government entities.
The author speculates the Moroccans, French, and Japanese would partner well in this endeavor. Due to Morocco's history and location, there is a strong French sub-culture in Morocco. France and Japan are two of several countries currently engaged in advanced Molten Salt Reactor research and are likely to have the scientific, engineering, and shipyard know-how to competently design and construct a Molten Salt Reactor barge at an efficient price.
Under the auspices of the International Atomic Energy Agency (IAEA): After construction, the "Y-1060" reactor barge would be towed to a remote location and test run on a dummy water load in the same manner as the ORNL Molten Salt Reactor Experiment was tested on a dummy air load. After testing, the reactor barge could either be towed back to the shipyard or somewhere else for modifications or, if none were deemed necessary, be towed to Jorf Lasfar power station, attached to the secondary salt heat exchanger house and put into service to see if they really will deliver 30-year power runs.

This practical experience could give the French and
Japanese a head start in the market of next generation reactors.

It is very unlikely that a poor country will have turbogenerators large enough to consume the energy a 1,000 megaWatt (electrical) thorium reactor barge can deliver. The leftover energy can be put to use by purchasing an new low-cost Indian or Korean made turbogenerator, steam generators, and cooling capacity and driving it as shown above.

Fuel poverty increased about 22% in UK 2008-2009
14 July 2011 - - - Green Car Congress, July 15, 2011
Fuel poverty in the UK increased about 22% from 2008 to 2009, according to the latest figures from the UK Department of Energy & Climate Change (DECC). A household is said to be in fuel poverty if it needs to spend more than 10% of its income on fuel to maintain an adequate level of warmth (usually defined as 21 °C for the main living area, and 18 °C for other occupied rooms).
In 2009, there were around 5.5 million fuel poor households in the UK, up from 4.5 million in 2008, according to DECC. In England, there were around 4.0 million fuel poor households, up from 3.3 million in 2008.
The increase in fuel poverty between 2008 and 2009 was largely due to rising fuel prices, DECC said. Gas prices rose by 14%, and electricity prices by 5%, between 2008 and 2009. Rising incomes, improvements in the energy efficiency of housing and social and discounted tariffs continue to help some households from falling into fuel poverty and, in some cases, have removed households from fuel poverty.
Fuel poverty figures are calculated across two years, and so price and income changes for two years need to be considered when looking at these figures, DECC said. Projections for England indicate there are likely to be around 4.0 million fuel poor households in 2010 and 4.1 million households in 2011. Although some price rises will impact on households in the latter half of 2011, it will be 2012 before the full impact of these are visible in the fuel poverty data.
Rising coal costs drive China's power producers into the red
June 21, 2011
China's
five biggest power companies have reported increasing losses in their thermal
power business ventures as they continue to struggle with rising coal costs and
capped electricity prices.
Combined losses for the five companies' thermal power ventures reached 12.16
billion Yuan (1.87 billion U.S. dollars) in the first five months of this year,
almost triple that of last year, the China Electricity Council (CEC) said
Monday.
These losses translated to an overall decrease in profits for the companies,
with a total of 5.57 billion Yuan in combined losses for the companies during
the first five months of this year, the CEC said.
The five power magnates include the China Huaneng Group, China Datang Corp.,
China Huadian Group, China Guodian Corp. and China Power Investment Corp. These
companies provide about half of the country's power.
The council warned that these companies' financial woes will make it more
difficult to ensure adequate supplies of power for the summer, when electricity
usage peaks.
According to the Bohai-Rim Steam-Coal Price Index, China's benchmark power coal
prices averaged 841 Yuan per metric ton from June 8 to 14, up 0.2 percent from a
week earlier. The benchmark price has been on the rise since March 16.
Last month, the government raised prices for electricity used for industrial,
commercial and agricultural purposes across the country's 15 provinces and
municipalities by
16.7 Yuan per 1,000 kilowatt-hours (kwh) in order to ease financial pressures on
the country's power companies.
However, prices for residential electricity remained unchanged.

Sea Water Desalination, Introduction:
Desalination of Sea Water
35 years ago, when I worked in another country, there were water rules that toilets were to be flushed only once a day. Worse, the country was in the tropics. Notice the water tanks on the roof. This is what you do when it may be a week or two between times when water is available. People living in Southern Calyfornia simply don't understand what their environmentalists are setting them up for by blocking nuclear desalination of sea water.
The "Toilet-to-Tap" recycling
facilities starting to spring up in the Southwest call for massive amounts
of electricity. The biggest single use of electricity in California is
pumping water.
"Desalination equipment is now in
use in over 120 countries, including Italy, Australia, Spain, Greece, Portugal,
Japan, China, India, Saudi Arabia, Oman, United Arab Emirates, Malta, Gibraltar,
Cape Verde and Cyprus.
There are over 21,000 desalination plants worldwide, producing over 3.5 billion
gallons of potable water a day. Overall, desalination plant capacity has
increased exponentially over the past 30 years.
Saudi Arabia leads the world in desalination and relies on it to meet 70 percent
of the country's drinking water needs."

Fresh from the Sea
By Mark Fischetti - From Scientific American, September, 2007
A combined electrical and desalination facility could be made by adding natural gas burning turbine generators.
After spinning the gas turbine electricity generator, the gas turbine's hot exhaust is then also used to heat the heat recovery steam generators to make steam to drive the the flash desalination boiler. There would be no environmental benefit from this arrangement.

NEWS ITEM:
Tampa Bay Water Leaders Considering "Drought Surcharge."
The St. Petersburg (FL) Times (4/7/09, Pittman) reports, "Tampa Bay Water
leaders are calling a 'drought summit' next month to gather local government
officials together to figure out ways to combat the water crisis. Among the
ideas they will explore: adding a 'drought surcharge' to water bills." The
"region has been caught in a drought for three years, to the point where the
U.S. Geological Survey reported this week that one of its gauges on the
Hillsborough River has reached a record low," while "weather experts predict the
dry spell is likely to continue until at least the start of the rainy season in
June." The article notes, "Tampa Bay Water's 15 billion- gallon reservoir has
already run dry, its desalination plant is struggling and the regional utility
is being forced to rely on pumping water out of the ground - even though that
practice is known to cause private wells, lakes and wetlands to dry up and may
lead to sinkholes."
Tampa, Florida, already has a 25 million gallon-a-day reverse osmosis desalination plant that supplies 10% of the Tampa area water, assuring that a drought won't leave Tampa dry. California has about 20 desalination plants in the planning stage. There are over 1,500 oil-burning desalination plants in the mideast all burning oil. Unfortunately, Reverse Osmosis Desalination technology has proven much more expensive and troublesome than Flash Distillation Desalination.
Tampa Bay Seawater Desalination: (Article below is from the Tampa Bay Water web site.)
Reverse Osmosis is used to extract fresh water from Tampa Bay's salt water.
Tampa Bay Seawater Desalination uses a process called reverse osmosis (RO) to produce drinking water from seawater. RO has been successfully used in nearly 200 water and wastewater treatment plants throughout Florida and produces some of the highest quality drinking water in the world.
Tampa Electric’s Big Bend Power Station already withdraws and discharges up to 1.4 billion gallons a day of seawater from Tampa Bay, using it as cooling water for the power plant. The Tampa Bay Seawater Desalination plant “catches” approximately 44 million gallons (mgd) of that warm seawater a day, separates it into drinking water and concentrated seawater.
The unused concentrated seawater is returned to TECO's cooling water where it is diluted with up to 1.4 billion gallons of water before it is discharged to the bay.
Desalination Process
There are basically three main treatment elements in the desalination process: pretreatment, reverse osmosis, and post-treatment.
Pretreatment
Pretreatment must be rigorous to remove sediment, organic matter and other microscopic particles to ensure efficient reverse osmosis operations.
Seawater entering the plant is first treated with chemicals to allow eventual settling of particles. It then goes through traveling screens that filter out shells and other larger debris. The screened water then goes through settling chambers. Similar to a traditional surface water treatment process, particles in the conditioned water clump together and settle out.
The next step in pretreatment is sand filtration, where smaller particles are filtered from the water. Next, diatomaceous earth filters eliminate microscopic materials before the water passes through cartridge filters, the last barrier before the RO process.
Reverse Osmosis
Reverse osmosis is what distinguishes a desalination plant from a traditional surface water treatment plant. During RO, high pressure forces the pretreated water through semi-permeable membranes, separating saltwater from freshwater and leaving salt and other minerals behind in a salty solution.
The size of each RO membrane pore is about .001 microns, which is about 1/100,000th the diameter of a human hair.
Post-treatment
The Tampa Bay Seawater Desalination Plant produces up to 25 million gallons per day of desalinated drinking water. Before that water is delivered to Tampa Bay Water, chemicals are added to stabilize the water. The water is then pumped to the regional facilities site, where the desalinated seawater is blended with treated drinking water from other supply sources before being delivered to Tampa Bay Water’s member governments.
Concentrate Return
At full capacity, the RO process will leave about 19 mgd of twice-as-salty seawater behind which will be returned to Big Bend’s cooling water stream and blended with approximately 1.4 billion gallons of cooling water, which will dilute it 70-to-1. At this point, its salinity will be only 1.0 to 1.5 percent higher, on average, than water from Tampa Bay. Environmental scientists say this slight increase falls within Tampa Bay’s normal, seasonal fluctuations in salinity.
This cooling water mixture then moves through a discharge canal, blending with more seawater, diluting the discharge even further. By the time the discharged water reaches Tampa Bay, its salinity is nearly the same as the bay’s. And, the large volume of water that naturally flows in and out of Tampa Bay near Big Bend will dilute it even further, preventing any long-term build-up of salinity in the bay.
Monitoring during the plant’s first year of operations showed no measurable changes in salinity, even when the plant was operating at maximum capacity.
There are many advantages to locating Tampa Bay Seawater Desalination beside the Big Bend power plant in addition to large volumes of cooling water. Tampa Bay’s relatively low salinity and the warm temperature of the power plant’s cooling water help optimize the RO process, keeping costs down. Tampa Bay’s frequent flushing also helps prevent the build-up of salinity.For more information: http://www.water-technology.net/projects/tampa/

Expertise and innovative R&D for the production of low cost electricity and
water
NDS is a group of world’s well known desalination experts, providing integrated
services for the deployment of desalination systems at the lowest costs.
Why NDS ?
In almost all countries, wishing to deploy integrated desalination systems, the
decision makers need to access immediately some basic facts and figures
regarding main characteristics of the proposed systems, cost estimates,
environmental impacts, etc.
By definition, since there are no on-going programs, the decisions have to be
delayed until collaboration agreements have been signed with suppliers,
engineers have been trained and numerous political discussions have taken place.
Obviously this not only takes a lot of time but also involves considerable
expenditure.
NDS is created to eliminate this very frequent problem. NDS is a startup whose
main objective is to provide all essential services to organizations or
countries, wishing to study or deploy integrated desalination systems.
Scope of Activities
A very unusual feature of NDS will be to train engineers / scientists in their
own laboratories to realize the specific studies or tasks required. This would
not only save considerable amount of time and money in negotiations and
political haggling but it would also create the skilled manpower in the client
countries with minimal costs, since travel and other expenses would disappear.
As the name indicates, NDS would be able to provide :
• Complete feasibility studies of integrated nuclear desalination systems for a
given site
• Training of young engineers / scientists in their country of origin
• Comparative economic evaluations of nuclear and fossil energy based integrated
desalination systems
• Planning and requirements for the implementation of nuclear energy programs
• development of computer codes for the economic evaluation of nuclear and
fossil energy based systems
• Development of specific computer codes and simulators concerning desalination
systems, etc.
• Safety studies of proposed nuclear desalination systems
• Liaison services between suppliers and clients
• Preparation of reports in English or French or Arabic or in any combination
thereof
Experience from some international (or bi-lateral) projects and studies
• Site specific feasibility studies for Tunisia; the TUNDESAL project (technical
coordination of a mixed team of enginerres from CEA, STEG (Tunisian utility),
SONEDE (Tunisian water company). The final report led STEG to opt for the
nuclear option.
• The EURODESAL generic study: included industrial companies such as ANSALDO
(Italy); AREVA NP(France); CANDESAL(canada); EMPRESSARIOS AGRUPADOS (Spain);
IRRADIARE (Portugal) and R&D organisations: University of ROME and CEA (France).
• Coordination and research for the Indo-french collaboration agreement in the
field of nuclear desalination.
• Elaboration of the technical programme for the LIBNDP1 project (French-Libyan
Collaboration programme) aimed at using the Tajoura reactor as a nuclear
desalination demonstration plant.
• Contributions to several IAEA TECDOCS; preparation of TECDOCS 1524 (Status of
Nuclear Desalination in IAEA Member States) and 1561 (Economics of Nuclear
Desalination: New Developments and Case Studies).

Expert Says Building Desalination
Plants Near Sewage Facilities Risks Contamination.
The Medical News (11/8, Mandal) reported according to an Australian National
University professor of infectious diseases and microbiology Peter Collignon,
"desalination plants that are built close to sewage outflows risk contaminating
drinking water." Collignon explained that membrane technology was subject to
errors when screening bugs. The article notes, "This comes coincidentally just
after a 'reporting error' by Sydney Water that showed E.coli had been found in
processed drinking water at its $1.9 billion Kurnell desalination plant in
Sydney's south." Collignon calls "constructing desalination plant so close to a
sewage treatment facility" as "one
of the fundamental things you wouldn't do."
MIT Team Develops Portable
Desalination System.
Environmental News Network (10/19, Gabel) reported, "A new system for
desalination has been designed by researchers at the Massachusetts Institute of
Technology (MIT). The system uses solar power to push ocean water through a
permeable membrane which is capable of removing salt and other minerals. Such a
portable system would be ideal for disaster-torn regions of the world which have
lost access to clean water." This system, which was designed by the MIT Field
and Space Robotics Laboratory, "can be deployed quickly in a crisis such as the
devastating earthquake that befell Haiti. After the quake, many people lost
their access to fresh drinking water, and many still suffer from dehydration."
This desalination plant is "portable and self-contained. It has no need for an
external power source thanks to its solar panels. Their prototype is able to
produce 80 gallons of water per day, and they estimate that a larger version
could provide up to 1,000 gallons per day."
World Likely To Face Water
Shortages Without Focus On Improving Irrigation.
The Financial Times (10/14, Harvey) reported that a small percentage of the
world's water supply can be used by humans, and this small percentage is
shrinking, as it faces more pressures from population growth, climate change,
pollution, and other factors. The Times notes that about a third of the US
population is likely to suffer water shortages in the next two decades, and it
will only get worse if people are unable to find better ways of managing their
water resources. Additionally, a report from the consultancy McKinsey, the
brewer SABMiller, and several others stated that as of 2030, global water
requirements will raise from ,500bn cubic meters today to 6,900bn cu meters.
Daniel Wild with Sustainable Asset Management in Switzerland is "astonished" at
"how inefficient the irrigation technologies used in agriculture actually are."
He advises we need to focus on improving irrigation systems.
China Working To Bring Water To Beijing.
The Los Angeles Times (9/29, Demick) reports, "The Chinese government is
planning to reroute the nation's water supply, bringing water from the flood
plains of the south and the snowcapped mountains of the west to the parched
capital of Beijing. First envisioned by Mao Tse-tung in the 1950s and now coming
to fruition, the South-North Water Diversion - as it is inelegantly known in
English - has a price tag of more than $62 billion, twice as expensive as the
famous Three Gorges Dam. It is expected to take decades to complete." Wang
Shushan, project head in the Henan province said, "This is on a par with the
Great Wall, a project essential for the survival of China. It is a must-do
project." According to Chinese scholar Orville Schell, China is, in effect,
"replumbing" the entire country, a feat that "no country has ever done
successfully in the past." Critics accuse Chinese officials of "robbing the
water...to supply Beijing."
Florida Desal Plant Scaled Down
After Counties Withdraw From Project.
The Daytona Beach News-Journal (8/12, Fernandez) reported that the "Palm
Coast's thirst" is "one reason the city must go ahead with plans for a downsized
desalination plant to turn sea water into drinking water," according to Mayor
Jon Netts. "Palm Coast and Leesburg -- and to a lesser extent DeLand and St.
Johns County -- are continuing studies on a proposed desalination plant." But
the project "has shrunk to a $200 million facility," said Scott Shannon of
Malcolm Pirnie, who said the facility "could be expanded to produce 25 million
gallons per day at a cost of $400 million." A more ambitious plan "foresaw an
initial plant size of 25 million gallons per day at a cost of $539 million,
which could be expanded to 80 million gallons per day for $1.3 billion." But
"instead of 11 cities and counties, only three cities and one county are now
involved," which "means fewer pipes are needed to move the water," Shannon said.
Colorado River Users Taking Steps To Avoid Water Restrictions.
The Arizona Republic (8/13, McKinnon) reports, "Drought-stricken Lake Mead
(NV) has dropped an additional 10 feet since summer 2009, and now Colorado River
users are scrambling to keep the reservoir full enough to avoid water
rationing." By 2011, the lake will is expected to "sink to within 9 feet of the
level that would trigger the first round of restrictions," which "begin with a
reduction in water deliveries to Nevada and Arizona." Hoping to postpone this,
"river users have built a reservoir west of Yuma, Ariz., to catch unused runoff,
paid farmers to leave fields unplanted and are negotiating with Mexico to leave
some of its allocation in Lake Mead while its farmers recover from an
earthquake." While "none of the steps will yield significant amounts of water,"
taken together these measures "could keep Lake Mead from sinking below the
drought triggers, buying time until a wet winter can replenish some of the water
lost to drought."
Feasibility Study To Consider Piping Water From Papua New Guinea To Queensland,
Australia.
The Australia Broadcasting Corporation (7/28, Fox) reports "successful tourism
entrepreneur" Fred Ariel "has signed a deal with the Papua New Guinean
government to look at piping fresh water 3,000 kilometres to Australia."
Specifically, Ariel "signed an agreement with the PNG government to conduct a
feasibility study." Although the plan "sounds crazy," Ariel argues that "despite
the huge construction costs...it would be cheaper than desalination plants and
water recycling." He explained, "The advantage that this project has is the
sheer volumes of water available."
Saudi Arabia Launches Floating
Water-Desalination Barge.
San Francisco's newsdesk.org (7/8) reported Saudi Arabia re-launched "the
world's largest floating desalination plant, with another floating plant close
behind." Each barge can produce "25,000 cubic meters" of fresh water per day.
Since "the stakes are high, the costs are frequently prohibitive, the technology
is controversial, the environmental impact is debatable...parched areas of the
world, from California to Australia, are watching closely." Desalination "has
had modest successes," but "it is generally regarded as a last resort for
generating fresh water." The cost of the technology "has come down steadily, and
it is becoming a more affordable means of meeting the world's growing freshwater
needs, according to a new report from Pike Research." The firm anticipates that
"global desalination investment will double from $8.3 billion in 2010 to $16.6
billion per year by 2016, representing cumulative spending of $87.8 billion
during that period."
Utility Inaugurates First
Large-Scale Desalination Plant In UK.
BBC News (6/3) reports the Duke of Edinburgh has inaugurated "the first water
desalination plant on the UK mainland." The London plant "is part of Thames
Water's plan to tackle water shortages in the capital. It said the £270m centre
would deliver up to 140 million litres of water to 400,000 homes in a drought."
The facility "will be run by using renewable biofuels such as cooking oil and
waste fat in an effort to reduce its impact on the environment. Drinking water
will be produced by treating a mixture of sea and river water from the River
Thames."
Meanwhile, the Guardian (UK) (6/3, Jowit) reports opponents of "the first
large-scale desalination plant" have argued the project "will use too much
energy and the company should be doing more to stop leaking pipes and reduce the
average water use of customers by installing more water meters and better
promotions."

Regarding the contribution of emissions to climate change, seawater desalination – in most cases the most energy intensive of potential water sources – would add in a significant way to an existing process, said the WWF’s Phil Dickie. A comparison of the emissions intensity of various desalination technologies – using an average European fuel mix for power generation – showed the great advantage of;
• Reverse Osmosis (RO) (1.78kg CO2 per m3 of produced water); over
• thermal distillation technologies of multistage flash (MSF) (23.41 kg CO2/m3); or
• multiple effect distillation (MED) (18.05 kg CO2/m3).”
Huge water-processing demand-load: “Precise figures depend on the location,” wrote Dickie, “but to take one example, the Pacific Institute estimated that the water sector was responsible for 19 percent of electricity use and 32 percent of natural gas use in California in 2001. The Institute calculated that the then current proposals to provide six percent of the State’s water through seawater desalination would have increased water-related energy use by five percent over 2001 levels. Spain’s Carboneras desalination plant uses one third of the electricity supplied to Almeria province. In a general sense, the increased demand for energy for desalination implies a commensurate increase in the carbon emissions linked to climate change.”
Clear advantage of
Reverse Osmosis process: “Worldwide, the
electrical power generating sector is the world’s most significant single
generator of carbon emissions, responsible for 37 percent of global emissions,
Dickie wrote. “Always operating large scale desalination plants are also
generally unsuited for variable power sources and tend to add to the base load
power requirements most likely to be generated by burning fossil fuels.

IBM, Saudi Arabia Research Center
Partner In Desalination Project That Uses Solar Energy.
The CNet (4/8) "Planetary Gear" blog reported, "IBM and Saudi Arabia's national
research group are opening a solar-powered desalination plant in the city of
Al-Khafji." The pilot facility "will supply water to about 100,000 people and
pump out about 30,000 cubic meters of potable drinking water per day. It will
run exclusively on solar-powered electricity, and showcase two technology
breakthroughs that were the result of a multi-year collaborative research
agreement signed in 2008 by IBM and the Saudi research group known as the King
Abdulaziz City for Science and Technology (KACST)."
Discover 's(4/8) "80beats" blog reported, "In the new desalination plant,
the Saudis hope to slash energy costs by deploying a new kind of concentrated
photovoltaic technology, which uses lenses or mirrors to focus the sun's rays
onto solar panels." This "technology will concentrate the sun 1,500 times on a
solar cell to boost efficiency. That's about three times the solar concentration
of most concentrating photovoltaic panels currently in operation."
SmartPlanet (4/8, Dignan) noted, These desalination efforts are critical
given that 97 percent of the Earth's water resides in oceans. If cheap
desalination methods can be developed clean water would be more accessible in
the developing world.
Saudi Arabia Building World's Largest Solar-Powered Desal Plant.
Technology Review (4/8, Patel) reports, "Saudi Arabia's national research
agency, King Abdulaziz City for Science and Technology (KACST), is building what
will be the world's largest solar-powered desalination plant in the city of
Al-Khafji." The facility "will use a new kind of concentrated solar photovoltaic
(PV) technology and new water-filtration technology, which KACST developed with
IBM. When completed at the end of 2012, the plant will produce 30,000 cubic
meters (8 million gallons per day) of desalinated water per day to meet the
needs of 100,000 people."
Monterey County, California, Supervisors Vote To Advance Desalination Plan.
The Salinas Californian (4/7, Hornick) reported, "Monterey County supervisors
have approved construction of a 10-million-gallon-per-day desalination plant by
2014," which "would serve Monterey Peninsula cities. Tuesday's vote is
contingent upon approval by the Public Utilities Commission." One of the
supervisors, Jane Parker, "voted for the desalination project, but cast the lone
vote against settlement and water purchasing agreements that her colleagues said
were essential to making it happen." Parker argued "the project contains too few
assurances for ratepayers about which costs will be passed on, and cited a rise
in cost estimates from $2,300 per acre foot of water initially to $4,000 per
acre foot." Parker "also distributed a list of 32 desalination plants worldwide,
of which 28 had costs under $2,000 per acre foot."
The Monterey County Herald (4/7, Johnson) reported, "Praising unprecedented
collaboration in the face of a looming deadline, the Monterey County Board of
Supervisors conditionally approved a proposed regional seawater desalination
project Tuesday." Supervisor Dave Potter, seeking "to defend the board's actions
as necessary despite the concerns raised by Parker and several others," said
"that it didn't make sense to risk implementation of the Carmel River water
cutback order or the issue going to litigation and state control." KCBA-TV
Salinas, CA (4/8), a Fox affiliate, also reported the story.
Malibu Wants Regional Water Board
To Rethink Ban On Septic Systems.
The Los Angeles Times (4/8, Groves) "LA Now" blog reported, "Malibu has asked
the Los Angeles Regional Water Quality Control Board to reconsider its Nov. 5
decision to prohibit septic systems in the coastal city's civic center area,
saying the ban's broad scope makes it technically unfeasible." City Manager Jim
Thorsen said, "The current plan leaves the city with a whole lot of treated
water and nowhere to put it." The city argued that "recent scientific studies
support the city's conclusion that civic center septic systems, governed by
strict rules regulating new systems, are not a significant source of groundwater
contamination or a significant cause of reduced water quality in the ocean or
Malibu Creek."
Global Water Crisis Prompts Surge In Desalination.
Johannesburg's Mail & Guardian (3/31) reported, "The world's unquenchable thirst
for clean water drove a record increase in the desalination of seawater and
reuse of sewage last year...as water-stressed countries around the world" are
trying "to build their way out of trouble." "As rivers, lakes and aquifers dry
up, rains become less reliable, and the cost of desalination has fallen,
communities in all parts of the world" are relying on "plants to turn oceans,
river estuaries, salty ground water and even sewage into clean water for
factories, farms and homes." The annual report by Global Water Intelligence
noted that "the rise in fresh water production was the biggest ever recorded at
9.5-million cubic meters a day" or "to about 10% of global capacity."
Professor Criticizes Public Perception About Recycled Water.
Australia's Illawara Mercury (4/1, Shaw) reports, "Attitudes to recycled water
are hampering the community's response to Australia's water shortage," said
Prof. Sara Dolnicar of University of Wollongong (New South Wales). According to
Dolnicar, "the 2006 project in the Queensland town of Toowoomba, to draw 25 per
cent of water from recycled effluent, had dramatically affected public opinion
of recycled water." Even though "it is possible to recycle sewage water into
safe, clean water for drinking and other household uses, the people of the town
blocked the proposal through a referendum. ... Prof Dolnicar hopes more
information might result in changes."
Canadian Startup Claims Its Desalination Method May Cut Energy Costs By 80%.
The Los Angeles Times (2/26, Cohen) "Greenspace" blog noted that "conventional
approaches to desalination," such as distillation and reverse osmosis, "are too
energy-intensive, and therefore too expensive," but "a Canadian startup,
Saltworks Technologies, is promoting a new, innovative process that it claims
will reduce desalination electricity costs by up to 80%. ... Saltworks'
thermo-ionic desalination process" is based on "the chemical nature of salt,
which is composed of positively charged sodium and negatively charged chlorine
ions." The startup "has already won several Canadian government grants worth a
total of about $2 million. The firm is operating a 1,000-liter-a-day pilot
project in a Vancouver harbor facility."
Authorities Considering Desalination Projects In California, Mexico.
California's Desert Sun (2/18, Matheny) reported, "A number of major
desalination projects are under consideration or actively in the works in
California and northern Mexico." Although "none of the projects call for
directly providing water to assist the Coachella Valley with meeting its future
needs," Coachella Valley Water District General Manager Steve Robbins noted that
"helping cities such as San Diego, Las Vegas and Phoenix has a ripple effect."
Robbins said, "The less pressure there is to take water out of the desert and
move it to the coast, the better off it is in the long run for the Coachella and
Imperial valleys, and the Salton Sea." Meanwhile, the San Diego County Water
Authority and other American water agencies in Nevada, Arizona, and California
are considering "helping to build seawater conversion facilities in Mexico,
providing a local water supply in exchange for a portion of Mexico's
contractually obligated share of Colorado River water."
Report: Higher Water Prices
Expected In Australia Due To Desalination Costs.
Bloomberg News (1/23, McDonald) reported on expected increases of "water
charges...in Australia due to the cost of building desalination plants,"
according to the country's media. The Australian newspaper cited the Water
Services Association of Australia as saying that Melbourne residents' water
bills, for instance, "may increase by about a third over the next three years to
A$904 ($814) a year, while Sydney residents may pay an extra A$103 a year by
2012."
Texas Desalination Facility
Profiled.
The El Paso Times (1/7, Burge) reports on "a $91 million desalination plant"
that is has produced for more than two years around four percent "of the
drinking water for customers of El Paso Water Utilities." The Kay Bailey
Hutchison Desalination Plant "converts brackish or salty groundwater into
drinking water." The facility is "operating far below capacity... producing
about 3.5 million gallons of drinking water a day," while it can "produce up to
27.5 million gallons a day." But the facility "could increase its production in
a matter of minutes." Considered "the world's largest inland desalination
plant," the facility also "includes a research center" to increase water
efficiency. Currently, however, "it costs about $1.70 to produce 1,000 gallons
of drinking water at the desalination plant." El Paso Water "estimates that it
costs 85 cents to treat the same amount of surface water and 50 cents to pump
1,000 gallons of fresh water out of the ground and disinfect it."
California Coastal Commission Upholds Permit For Massive Desalination Project.
The North County Times (CA) (12/11, Fikes) reports that the California Coastal
Commission denied "the revocation request" by the environmental groups San Diego
Coastkeeper, the Surfrider Foundation, and the Coastal Environmental Rights
Foundation, which "had argued that, in obtaining a coastal development permit,
developer Poseidon Resources Corp., had withheld or misstated information about
the desalination plant's impact on the environment." Upon completion "the plant
will be capable of producing 50 million gallons of drinking water a day, enough
to meet the needs of about 9 percent of San Diego County's population."
Water World (12/10) noted, "Poseidon has worked in partnership with the City of
Carlsbad since 1998 to build the desalination plant, which will have the
capacity to produce 50-million-gallons-per-day of high quality drinking water
and serve 300,000 residents annually."
KGTV-TV San Diego (12/11) reports that Scott Maloni, vice president of Poseidon
Resources, called on "project opponents to put an end to their senseless and
meritless attack. ... Two lawsuits attempting to halt the project have also been
unsuccessful." According to Reuters (12/11), the plant will be the largest
seawater desalination facility in the Western Hemisphere
Vancouver Startup Developing
Lower Cost Desalination Technology.
Business in Vancouver (12/9, Cherewayko) reported, "Saltworks Technologies is
developing a saltwater-powered battery it says removes salt from water at a
fraction of the cost of other desalination processes." The initial idea was "how
to use a thermodynamics law, in which the tension between two different
concentrations of the same solution converts energy." Ben Sparrow, the head of
the Saltworks Technologies, "applied the law to salt water and realized that the
voltage from the ions of a hyper-saline solution could pull salt from a third
water stream as the ions naturally move from a high to low concentration of salt
water." Now, four years later, the startup is "making the final adjustments on a
saltwater-powered battery that can desalinate water at a cost" of "up to 80%
less than that of existing processes." While reverse osmosis and electrodialysis
"require external and often plentiful sources of electricity," Saltworks'
technology needs "only to power low-pressure pumps and a few other moving
parts."
Official: Massachusetts
Desalination Project Could Be Ready In One Year.
The Herald News (MA) (11/24, Dion) reports, "The next step in the construction"
of the water desalination plant in Swansea "is complete with the installation of
an intake screen that will draw water from the Palmer River," according to Water
District Superintendent Robert Marquis, who added that "he expects the entire
$18 million project to be totally online by November 2010. 'This will draw 5,400
gallons of water a minute from the river.'" Marquis said that the water intake
"will draw the water during two six hour cycles a day, at low tide, adding that
the water is at its lowest salinity at low tide." He explained that "water is
drawn into the intake gently and, while there is a screen inside the intake, the
intake of water from the river should be slow enough to keep debris from being
'sucked' into the unit."
Chile Calls On Mining Companies To Find Alternative Water Sources.
SteelGuru (11/22) reported, "Based on the findings of a study released on water
usage in domestic mining by Chile's state copper commission Cochilco" the
country's mining minister "said that if companies do not start searching for
alternative water sources now, it is highly likely there will not be enough
resources for all the red metal projects slated to begin between now and 2020."
Santiago González said that there is "no point carrying out projects if we don't
have the necessary water resources in order to [develop] them in the years to
come." The minister "added that desalination...or direct use of seawater...are
the 2 best alternatives today to relying on natural aquifers that are becoming
scarce."
Mining Company Announces Plans For $250-Million Desalinization Plant.
SteelGuru (11/20) reported that "Chilean mining giant" CAP revealed plans to
build a $250-million "desalinization plant to provide water for its iron mining
operations in Chile's Atacama area." Under the plans, more than "750 workers
will construct the plant, an underwater emission pipe and a sea water collection
facility near the town of Puerto Totoralillo. A 120 kilometers aqueduct will
then transfer the water to Cerro Negro Norte mine in the Copiapo Valley."
California Paper Criticizes
Decision To Finance Desalinization Plant.
California's Daily Breeze (11/22) editorialized about the Metropolitan Water
District of Southern California, which recently "has had some rough criticism,"
last week made "another controversial decision" which "would help finance a
desalination plant that should never be built and could cost water customers
$350 million over the next 25 years." Poseidon Resources LLC is seeking "to
build a plant in north San Diego County to desalt sea water, and wants some
public help to finance it. In addition to the MWD subsidy, the company wants
state approval to sell tax-free municipal bonds to cover the rest of its costs."
Everybody except Poseidon, argues the Breeze, "would be much better off without
this project," which it characterizes as "environmentally unsound because...it
would suck sea creatures directly into its intake tubes and destroy them. It is
financially unsound because, as opponents correctly estimate, its costs will be
so high nobody would want to buy its product." The Daily Breeze also questioned
Poseidon's "performance record."
Canadian Firm Announces More Efficient Desalination Method.
CleanTechnica (11/16, O'Callaghan) reported that Saltworks Technologies claims
that its desalination technology reduces "the electrical energy required for
desalination by over 70%." The Canadian firm reports that it "can produce 1m3 of
water with 1kW hour of electrical energy, compared to the 3.7kWhr per m3, which
is what is currently achievable using reverse osmosis with the use of energy
recovery devices." The firm uses "solar heat (or waste heat) to evaporate water
and concentrate salt water. They are converting solar energy into osmotic energy
by doing this. They then use this osmotic energy to desalinate water." Since
"the system is not under pressure," the firm "can use plastic pipes instead of
steel pipes, potentially reducing capital costs also."
Desalination Plant Restarts After Shutdown.
Following a story from yesterday from the St. Petersburg (FL) Times, Tampa Bay
Online (11/10) reported, "The region's desalination plant started running
[Tuesday] after being shut down nearly 48 hours because of problems caused by a
power failure on Sunday." The facility "in Apollo Beach was running at its
maximum capacity of more than 25 million gallons a day when it lost power,"
which "caused valves in the plant to shut and water to reverse direction at high
pressure." According to a spokeswoman for Tampa Bay Water, the plant's owner,
the effect known as "water hammer," caused a number of "pipes to leak and the
plant had to be shut down."
The St. Petersburg Times (11/11, Pittman) notes that "the $140 million plant" is
"the largest" in the US. "At the time the power went out, the plant had been
running above its capacity of 25 million gallons of water a day, as the utility
tries to make up for pumping too much water out of the ground during the spring
water shortage."
Company Touts Sun-Powered Ionic System As More Energy Efficient Than
Distillation, RO.
Control Engineering (11/6, Welander) noted that "distillation works and has been
around for a long time, but is energy intensive. Reverse osmosis (RO) is better,
but creating the high pressures involved requires electrical power (typically at
least 3.7 kWh for 1,000 liters) and equipment able to withstand the stress.
Where there's electricity, there's usually carbon." A new company, Saltworks
Technologies, "has developed a technology unlike the others," taking "advantage
of the characteristics of sodium and chlorine ions. Using a bit of sun-powered
evaporation to create a salt concentration imbalance, the approach induces the
ions to leave the solution using something called an ion bridge," and "the only
electrical power needed is to move the water between various tanks. The
equipment can be built of plastic to avoid corrosion problems." According to
Saltworks, "this technology is highly scalable so it promises to be practical
for a single home to a central supply for a community."
Engineer Tells Panel Pilot Desalination Plan Not Affected By Red Tide.
The Brownsville (TX) Herald (11/4, Phillips) reports, "NRS Consulting Engineer
Jake White had good news for Laguna Madre Water District Directors Wednesday
evening," telling them that "the red tide has not affected the pilot
desalination plant at Andy Bowie Park to any noticeable degree." The engineer
reported that "water taste and quality has not been affected in the least," as
"the plant is removing all traces of toxin from the water." White also said that
toxins would not "have any deleterious effect on the metal components of the
pilot plant."
AquaSure Agrees To $1.5 Billion Loan For Desalination Project.
Bloomberg News (11/4, McDonald) reports, "AquaSure, a group of investors
building Australia's biggest water desalination plant, agreed to a A$1.7 billion
($1.5 billion) loan to help fund the project," sources said. "Banks offered to
lend more than AquaSure sought, meaning the Victoria state government won't need
to make up a shortfall." Bloomberg notes, "Suez Environnement Co., Thiess Pty.
and Macquarie Group Ltd. are among members of AquaSure, which won a government
contract in July to build the desalination plant in Victoria." AquaSure will
fund, design, construct and operate a reverse-osmosis plant capable of providing
a third of Melbourne's annual water supply."
Cheaper desalination - "Current thinking" - A fresh way to take the salt out of seawater
Oct 29th 2009 From The Economist print edition
THERE is a lot of water on Earth, but more than 97% of it is salty and over half of the remainder is frozen at the poles or in glaciers. Meanwhile, around a fifth of the world’s population suffers from a shortage of drinking water and that fraction is expected to grow. One answer is desalination—but it is an expensive answer because it requires a lot of energy. Now, though, a pair of Canadian engineers have come up with an ingenious way of using the heat of the sun to drive the process. Such heat, in many places that have a shortage of fresh water, is one thing that is in abundant supply.
Ben Sparrow and Joshua Zoshi met at Simon Fraser University in Vancouver, while completing their MBAs. Their company, Saltworks Technologies, has set up a test plant beside the sea in Vancouver and will open for business in November.
Existing desalination plants work in one of two ways. Some distil seawater by heating it up to evaporate part of it. They then condense the vapor—a process that requires electricity. The other plants use reverse osmosis. This employs high-pressure pumps to force the water from brine through a membrane that is impermeable to salt. That, too, needs electricity. Even the best reverse-osmosis plants require 3.7 kilowatt hours (kWh) of energy to produce 1,000 liters of drinking water.
Mr Sparrow and Mr Zoshi, by contrast, reckon they can produce that much fresh water with less than 1 kWh of electricity, and no other paid-for source of power is needed. Their process is fuelled by concentration gradients of salinity between different vessels of brine. These different salinities are brought about by evaporation.
The process begins by spraying seawater into a shallow, black-bottomed pond, where it absorbs heat from the atmosphere. The resulting evaporation increases the concentration of salt in the water from its natural level of 3.5% to as much as 20%. Low-pressure pumps are then used to pipe this concentrated seawater, along with three other streams of untreated seawater, into the desalting unit. As the diagram explains, what Mr Sparrow and Mr Zoshi create by doing this is a type of electrical circuit. Instead of electrons carrying the current, though, it is carried by electrically charged atoms called ions.
Salt is made of two ions: positively charged sodium and negatively charged chloride. These flow in opposite directions around the circuit. Each of the four streams of water is connected to two neighbors by what are known as ion bridges. These are pathways made of polystyrene that has been treated so it will allow the passage of only one sort of ion—either sodium or chloride. Sodium and chloride ions pass out of the concentrated solution to the neighboring weak ones by diffusion though these bridges (any chemical will diffuse from a high to a low concentration in this way). The trick is that as they do so, they make the low-concentration streams of water electrically charged. The one that is positive, because it has too much sodium, thus draws chloride ions from the stream that is to be purified. Meanwhile, the negative, chloride-rich stream draws in sodium ions. The result is that the fourth stream is stripped of its ions and emerges pure and fresh.
It is The idea that could be built equally well on a grand scale or as rooftop units the size of refrigerators. Of course, a lot of clever engineering is involved to make it work, but the low pressure of the pumps needed (in contradistinction to those employed in reverse osmosis) means the brine can be transported through plastic pipes rather than steel ones. Since brine is corrosive to steel, that is another advantage of Mr Sparrow’s and Mr Zoshi’s technology. Moreover, the only electricity needed is the small amount required to pump the streams of water through the apparatus. All the rest of the energy has come free, via the air, from the sun.
California Water Agencies
Consider Desalination.
KPIX-TV San Francisco (10/17), a CBS affiliate, reported, "Four Bay Area
water agencies have teamed up to possibly build as many as three desalination
plants, two on the bay, one along the ocean." The article noted, "The East Bay
Municipal Utility District (EBMUD), Hetch Hetchy, Contra Costa Water District
and Santa Clara Valley Water District are so worried about future water
supplies," and "they are talking about sharing the cost of building the plants."
According to the water agencies, "building an array of desalination plants might
mean not having to build new dams and reservoirs." KPIX pointed out that, "until
recently, desalination wasn't considered an option because the costs were too
high," but, according to Mike Tognolini of EBMUD, "there has been great
improvement in the technology that's used to desalinate water and because of
that the cost to desalinate water is dropping dramatically."
Massachusetts Desalination Plant Poised To Open Soon.
The Herald News (MA) (10/6, Pateakos) reports, "The final leg of the
region's first public desalination facility will soon begin, as MassHighway has
granted approval for the Swansea Water District to install two water pipes under
Interstate 195." According to Water District Superintendent Robert Marquis, "the
boreholes, which will be drilled underneath the highway to allow for a 16- and
20-inch water pipe to be installed, will have no effect on traffic," as they
"will be dug far enough under the ground to eliminate the need for any lane
closures." According to the article, "There will be a pre-bid conference on Oct.
13 for the boring work, which is estimated to cost around $885,000. Bids must be
received by Oct. 22."
Work Begins On Controversial Australian Desalination Plant.
ninemsn (10/6) reports, "Building has started on Victoria's controversial
desalination plant which will provide up to 150 billion liters of water each
year to Melbourne from the end of 2011." AquaSure, "the consortium constructing
the $3.5 billion plant," includes Suez Environment, Degremont, Thiess and
Macquarie Capital Group." The contract calls for "construction and operation of
the desalination plant, an 84km transfer pipeline, plus the construction of
underground power and sourcing renewable energy."
The Australian Broadcasting Corporation (10/6) reports, "AquaSure
consortium...has promised to build a windfarm...to offset the plant's energy
needs." But despite that "the project has drawn strong opposition from
environment groups and the local council. A small group of protestors were on
hand to heckle" Victoria Water Minister Tim Holding, "saying the plant is bad
for the environment and the local community." But the minister said that such
projects "are necessary. 'We've got to be honest with people, you can't respond
to 13 years of the longest and driest drought that we've ever had, you can't
prepare our community for climate change, without investing in projects to
augment our water supplies,' he said."
"Water-Rich" North-Central Florida Urges Growing Cities To Pursue
Desalinization.
Politicians in Florida "representing the water-rich north-central region
want the water to stay right where it is," while "politicians representing the
growing cities want the water to go where it's needed," the Lakeland (FL) Ledger
(10/3, A10) reported. "It was no surprise to receive a press release this week
from Alachua County's State Sen. Steve Oelrich urging the St. Johns Water
Management District not to withdraw water from the St. Johns and Ocklawaha
rivers for drinking purposes. If cities like Jacksonville need more water,
Oelrich said, they should invest in desalination plant." This, said Oelrich,
"sets a dangerous precedent for other areas with water shortages." But according
to the Ledger, "Sen. Oelrich is naive if he really believes it's possible to
keep the Rodman intact without having it eventually tapped as a drinking water
source. It is too big and too convenient a target of opportunity for powerful
urban politicians to ignore for long."
Jordan To Proceed Alone With Dead
Sea Pipeline.
AFP (9/27) reported, "Jordan has decided to go it alone and build a
two-billion-dollar pipeline from the Red Sea to the Dead Sea without help from
proposed partners Israel and the Palestinian Authority, an official told AFP."
Fayez Batayneh, who represent Jordan "in the mega-project to provide drinking
water and begin refilling the Dead Sea, which is on course to dry out by 2050,"
said, "Jordan is thirsty and cannot wait any longer. ... Israel and the
Palestinians have raised no objection to Jordan starting on the first phase by
itself." Under the plan, the pipeline would "draw off 310 million cubic metres
(10.5 billion cubic feet) of water each year, of which 240 million will be fed
into the desalination plant at the Jordanian Red Sea port of Aqaba, enabling an
annual production of 120 million cubic metres of drinking water."
Desalination Touted As "Best Alternative," Most Cost Efficient.
The Daytona Beach (FL) News-Journal (9/25, Fernandez) reports, "Prepare to
be desalinated -- eventually. And it's a good thing. Those were among the
messages delivered by a panel of experts during a public meeting Wednesday night
in Marineland (FL) to discuss a proposed water desalination plant to supply the
region's taps." Jerry Salsano of Taurant Consulting said that, according to
"some of the partners involved" in the Coquina Coast Seawater Desalination
Project, "a desalination plant is the best alternative for the lowest possible
cost." The partners "are looking at building a desalination plant on land or on
a ship by 2017." Menawhile, "no site has been selected for the plant, which
would need about 50 acres and be linked to 190 miles of transmission lines." In
order "to produce 25 million gallons of drinking water daily," the facility
"would have to draw about 63 million gallons of seawater every day."
Central Florida Desalination Project Discussed.
The Orlando Sentinel (9/23, Lelis) reports that in Central Florida "a
multimillion-dollar project that could send treated seawater through miles-long
pipelines to faucets in DeLand, Mount Dora or Leesburg" was discussed at a
public meeting last night. It is estimated that the Coquina Coast seawater
desalination project "could deliver desalted water to a host of cities and
county utilities looking for new sources of potable water." The three cities
"are interested in whether seawater is a viable option, but none of the
governments has committed to building what could be a $460 million to $1 billion
project capable of producing 50 million to 80 million gallons of water a day."
In the meantime, "the Coquina Coast group is reviewing options -- primarily a
land-based plant or a vessel that would treat the water at sea and pipe it into
a distribution center."
Lawsuit Aims To Stop California Desalination Project.
The AP (9/23) reports, "Opponents of a plan to turn millions of gallons of
salt water from San Francisco Bay into drinking water for residents of Marin
County have sued to stop the project." The lawsuit claims that "the desalination
project would increase energy consumption, pollute the bay and fuel population
growth." The Marin Municipal Water District board "last month approved a
desalination facility that could convert 5 million gallons of bay water into
drinking water each day." While "officials say the county needs a new source of
water that is drought-proof," opponents say "the county should focus on
conservation."
Activists To Sue Over California Desalination Project Changes.
The San Diego Union-Tribune (9/17, Burge) reports, "Environmental groups
haven't given up their effort to derail the proposed ocean-water desalination
plant in Carlsbad (CA)," and are "telling the City Council, after it approved
project changes Tuesday night, that they'll sue." The changes would consolidate
"some of the plant's operations" and include "six miles of pipe that will carry
the cleansed water inland." The Union-Tribune notes that the council approved
the changes "as an addendum to the environmental impact report it OK'd in 2006,
without reopening the time-consuming environmental review process," as "the
desalination plant's developer, Poseidon Resources," had to "meet all conditions
by Nov. 14" in order "to obtain a permit from the California Coastal
Commission." But an attorney for the Coastal Environmental Rights Foundation and
Coastkeeper "told the council it should have reopened the environmental process
to allow for public review."
NATO Awards Grant For Two Middle
East Desalination Projects.
Israel 21c (9/15, Kloosterman) reports, "A new Israeli technology for
desalination is the centerpiece of a NATO grant that promotes collaboration
between Israel and Jordan and could save water and energy across the globe." The
grant will cover the development of "two inland water desalination plants -- one
in Israel and one in Jordan," and will get "two Middle East universities
collaborating." Under "the terms of the project, three universities -- Ben
Gurion University in Beersheba, the Hashemite University of Jordan and the
University of Colorado in the United States -- are to implement a new Israeli
reverse osmosis desalination technology at two pilot sites." The technique was
"developed originally at Ben Gurion University," and "a new six-person company
called Rotec is commercializing" it. The role of "the universities, as
partners," is to "implement the new reverse osmosis Rotec technology" at the
water plants.
California Water Crisis A
National Priority, Federal Agency Says.
The AP (8/13) reports, "California's ongoing water crisis is a major
national priority, akin to restoring the Chesapeake Bay or Florida's
Everglades," Deputy Interior Secretary David Hayes said Wednesday. Hayes also
said that "Interior Secretary Ken Salazar will hold a public meeting in
Washington next month to discuss plans to restore the Sacramento-San Joaquin
Delta, the freshwater estuary that supplies drinking water to two-thirds of
Californians and is one of the most vital wildlife habitats on the West Coast."
While about 50 "mayors are calling for President Barack Obama to visit the area
himself, saying three years of drought coupled with court-ordered protections
for threatened fish species have sapped critical irrigation supplies,"
California "and federal agencies are evaluating several conservation strategies
for the estuary, including a controversial proposal that could cost up to $17
billion to build a canal to move water around the ecosystem."
Japanese Steelmaker To Study Australia Water Supply Project.
Bloomberg News (7/23, Suga) reported, "JFE Holdings Inc., Japan's second-largest
steelmaker, said its engineering unit will start a study this year on a water
supply project in Queensland, Australia." JFE Engineering Corp., said that it
"plans to operate a test water treatment system at a plant in the state's
southeast for three years before beginning commercial operations in the year
starting April 2014." The project aims to "ease supply shortages in Queensland's
southeast as the population is forecast to increase by 50 percent to 4.2 million
by 2030."
Electric Sewage-Treatment
Technology Said To Be Eco-Friendlier Than Biological Processes.
British Columbia's Goldstream News Gazette (7/24) reports that Boydel Wastewater
Technologies Inc.' uses "an electricity based process called electrocoagulation
(EC) to treat sewage instead of biological processes." Ledcor, the company which
is testing Boydel's technology, said that "the process can treat to secondary
levels, as required by the province, as well as remove pesticides, heavy metals
and pharmaceuticals from the waste stream. It will also be able to accommodate
the treatment of sewage and stormwater in one facility." Ledcor also said that
"because the system uses electricity over biological processes to break down the
sewage, far less greenhouse gas is emitted."
Study Suggests California Alter
Its Water Strategy.
The AP (7/23) reports, "By investing in water-saving technology,
California's drought-burdened farmers could save enough water annually to fill
four times over a reservoir," which Gov. Arnold Schwarzenegger supports
building," according to a study by the Pacific Institute, which "urges
regulatory agencies and lawmakers to focus on farm investments rather than large
infrastructure projects." Farm investments "could ensure more reliable water
supplies as a warming planet increases the length and frequency of droughts, the
report suggested." The study noted that "water-intensive flood irrigation has
certainly declined since 2001...but the method still is widely used in some
areas," but that a great number of farmers "with historic water rights have no
incentive to conserve," since "they get their full allocation of canal water
every year no matter the weather conditions, while others get none." The report
recommended "water contracts should be renegotiated to reflect the new reality
of a dwindling supply."
Portable Desal, Filtration System
Developed.
The Chemical Engineer (UK) (7/14, Duckett) reported, "Chemical engineers at
UCLA's school of engineering and applied science...have helped develop a new
mini-mobile-modular desalination and filtration system (M3)" and "has
successfully tested the unit in California with a view to helping solve the
state's water shortage problems." The system marks "quite a change from the
costly and often time-consuming practice of building individual pilot plants to
evaluate and demonstrate the feasibility of desalination for each source of
water." The system "was developed by staff and students from the chemical,
electrical and civil engineering departments with specific expertise in control
theory and optimization, process design and monitoring, computational fluid
dynamics, thermodynamics, and software development," and in collaboration "with
Victoria University in Australia, Ben Gurion University in Israel, and Tarragona
University in Spain."
The Engineer (UK) (7/14) quoted Yoram Cohen, the lead researcher and a UCLA
professor of chemical and biomolecular engineering, who said, "In the first part
of the reverse-osmosis process, 65 per cent of the water that was fed in was
recovered as drinking water." He added, "We can potentially recover up to 95 per
cent using an accelerated chemical demineralization process that was also
developed at UCLA." While the M3 "is compact enough to be transported anywhere
in the back of a van, it can generate 6,000 gallons of drinking water per day
from the sea or 8,000 to 9,000 gallons per day from brackish groundwater."
California To Break Ground On
Desalination Plant.
The Wall Street Journal (7/9, A4, Shankman) reports, "Early next year, the
Southern California town of Carlsbad will break ground on a plant that each day
will turn 50 million gallons of seawater into fresh drinking water." According
to the article, "the $320 million project, which would be the largest
desalination plant in the Western Hemisphere, was held up in the planning stages
for years. But a protracted drought helped propel the project to its approval in
May -- a sign of how worried local authorities are about water supplies." Under
the plan, "the desalination plant would use water that flows by gravity from the
ocean across a manmade lagoon and into the facility through 10 large pumps. The
plant would then blast it through a filter, extracting fresh water and leaving
behind highly pressurized salty water. The process would provide enough water
for 300,000 people each day."
California May Approve More Lenient Graywater Code This Summer.
The Los Angeles Times (7/6, Carpenter) GreenSpace blog reported, "California may
adopt a more lenient gray water code as early as August." Under the proposed
regulation, "a clothes washer or other single-fixture, residential gray water
system, such as a shower, could be installed or altered without a construction
permit. That's a complete reversal of the present state requirement that
homeowners installing systems to recycle the waste water from their sinks,
showers, bathtubs and laundry machines conform to Appendix G of the California
plumbing code, which requires that gray water systems not only be permitted by
the appropriate administrative authority but installed underground with
extensive filtering apparatus."
Foreign Countries, California
Debating Desalination Plants' Viability.
The Wall Street Journal (6/4, Johnson) Environmental Capital noted that "the
debates over what to do about water and electricity have a lot in common. There
are ardent supply-siders who say we need to produce more of the stuff, and there
are equally devoted demand-side types who stress conservation and efficiency."
Currently "in Spain, the Middle East, and Australia, thirsty governments are
building big desalination plants to turn salty seawater into drinking water. One
big downside is that the process is expensive-and uses a lot of energy." Such a
"debate is coming to a head in California, too, which is facing its own water
crisis. Plans are afoot to build as many as 20 desalination plans across the
state. At issue is how to meet an expected increase in water use even as
traditional water sources, from rivers to reservoirs, are getting drier."
American Water Wins Texas Desalination Contract.
The Philadelphia Inquirer (5/14) reported, American Water said Thursday
"that its subsidiary had won a $500,000 contract to run a desalination pilot
plant in Laredo, Texas." Under the agreement, the Applied Water Management "will
be using a new desalination technology, designed to reduce capital and operating
costs. Applied Water is expected to begin engineering work this month, and to
begin running the facility by the end of this year."
The Philadelphia Business Journal (5/15, Key) adds that the plant is planned "to
provide additional fresh water for the 215,000 residents of Laredo, which is
located in a semi-arid area on the Texas-Mexico border. Laredo is reaching the
limit on the amount of water it can draw from the Rio Grande River and its
ground water has been affected by salt intrusion."
San Diego Approves Large Desalination Plant.
The AP (5/14) reports, "San Diego's water board gave final approval
Wednesday for construction of the largest water desalination plant in the
Western hemisphere." Under the plans, "the $320 million project proposed by
Poseidon Resources could come online by 2012 in Carlsbad and produce 50 million
gallons of drinking water a day, or 10 percent of the supply for San Diego
County." The AP notes, "The pressure to find new sources of clean water has been
increasing with drought conditions and as traditional sources across California
are becoming more unreliable."
However, according to the Los Angeles Times (5/13, Perry) L.A. Now blog,
"environmentalist activists, who believe the project would harm the coastal
environment, plan to appeal to the State Water Quality Control Board and to
continue at least three lawsuits aimed at blocking the project."
In addition, the North County (CA) Times (5/14, Fikes) notes, Poseidon Resources
"still needs to raise the money" for the project. If built, "the plant could
serve as a template for other desalination plants on the California coast, where
densely populated urban areas are increasingly straining their water supplies."
South Africa Warned Of Water
Price Increase.
Creamer Media's Engineering News (5/22, Parker) reports, "Water Institute of
South Africa (Wisa) president Dr Heidi Snyman has warned that the price of
water" to South African consumers may "increase, owing to the increasingly
complex methods sometimes needed to draw clean water from new sources." Snyman
"said that the continued pollution and mismanagement of existing resources meant
that the water industry relied heavily on recycling wastewater and processes
such as desalination to be able to provide the growing population with clean
water." The article noted, "Water price hikes would affect the entire economy,
as water is a major input into most industries' production processes." Snyman
aid, "Our strategic drives will focus on making a real difference in the water
sector by increasing membership benefits, promoting volunteerism, ensuring an
African and global presence and financial sustainability."
In California, Desalination of Seawater as a Test Case By FELICITY BARRINGER Published: May 14, 2009
SAN FRANCISCO — The vast $320 million desalination plant approved this week by San Diego’s regional water authorities is likely to serve as a test case for whether such a large project can meet its goals while safeguarding its Pacific environment.
The plant, to be built near Carlsbad, north of San Diego, will be the first large-scale desalination operation on the West Coast and the largest in the hemisphere. “If they build it well and it operates well and the price is right, we will see more,” said Peter Gleick, the cofounder and president of the Pacific Institute in Oakland, Calif.
“I think there’s going to be some hesitancy to really expand desalination until this plant is up and running,” he added. “There’s going to be hesitancy on the part of everyone — regulators, water agencies and municipalities.”
Other ambitious desalination projects are being considered along the California coast, from Marin County just north of San Francisco to Santa Cruz, Monterey, Long Beach and Huntington Beach. Cities, water companies and environmentalists are likely to scrutinize how the plant near Carlsbad performs financially and technically and weigh its environmental impact.
Environmentalists have battled the project in lawsuits, raising concerns about the amount of fish that will be killed by the pumping process and about potential change to the aquatic ecosystem when leftover brine is returned to the sea. So far they have not won any victories.
Poseidon Resources pursued the project for over six years before gaining final approval on Wednesday from the San Diego Regional Water Quality Control Board, the last of four agencies whose assent was needed.
The plant will filter 100 million gallons of seawater daily, taking salt out by filtering it through fine membranes, a process called reverse osmosis. If construction proceeds as scheduled, it will produce 50 million gallons of drinking water by 2011.
The plant would provide water to nine municipal water agencies in northern San Diego County, filling 10 percent of the county’s drinking water needs. Its capacity makes it one of the biggest outside the Middle East.
The California Coastal Commission, one of the agencies that approved the project, raised questions last month about whether Poseidon’s plan to mitigate the damage to aquatic life was sufficient. Poseidon plans to create 55 acres of new coastal wetlands to mitigate the loss of fish. The Coastal Commission suggested that a minimum of 66 acres was required, but the regional water board signed off on the original plan.
Marco A. Gonzalez, a lawyer for the Surfrider Foundation and the Planning and Conservation League, said he would appeal the regional board’s decision to the state board.
Barcelona's New Desalination
Plant To Provide 44 Million Gallons Of Water Per Day.
BBC News (7/22) reports, "A desalination plant has opened near Barcelona - said
to be the biggest of its type in Europe - to ease chronic water shortages."
Officials say that the plant, which "went into operation" early this week, "will
provide 24% of the water consumed in the Barcelona area," or about "200m litres
(44m gallons) of drinking water daily for the city's 4.5 million people."
Meanwhile, two other "desalination plants are being built in the Catalonia
region."
Florida Local Governments Looking Into
Desalination.
The DeLand-Deltona Beacon (FL) (5/12, Everson) reports, "Uncertain about the
area's future water needs, Volusia County has cautiously expressed interest in a
possible desalination plant in Flagler County to treat ocean water for use in
homes and businesses." So far, "several localities are taking part in the
preliminary discussions about the Coquina Coast Desalination Project," and "the
exact price tag of Coquina Coast is not yet known, but Volusia County Utilities
Director Gloria Marwick said she has heard estimates as high as $1 billion." In
addition, "the refined water from Coquina Coast will be quite expensive -
perhaps too pricey - for both the utilities buying it and the customers paying
for it." It is expected that future water needs and technological improvements
will narrow the gap.
Tampa Considers Treating Wastewater For Drinking Supplies.
The St. Petersburg (FL) Times (5/8, Zink) reports that Tampa City Council
member Charlie Miranda "revived a decades-old proposal to send treated
wastewater back into the public drinking water supply," saying that "this is the
only way for the city...to become self-sufficient and not have to spend more
money buying water." Tampa "currently dumps 55 million gallons of treated
wastewater into Tampa Bay each day. The water is purified to the point that it
can be used on lawns, but the city's reclaimed water system reaches only about
8,000 property owners." While, according to Miranda, "it will never be
financially feasible to expand the system enough to maximize the use of the
water," it can "make financial sense to build a wastewater treatment plant to
further purify the water. The water could be put back into the ground, where it
would be naturally filtered before reaching the Hillsborough River and treated
again before heading to customer's taps."
San Diego Poll Shows Increased Support For Recycled Sewage.
According to the results (pdf) of a public opinion poll released last week
by the San Diego County Water Authority, the Voice of San Diego (4/24, Davis)
reported, "63 percent of respondents" support "the use of recycled sewage to
boost drinking water supplies. That's up from 28 percent in 2005." However,
"more of the public (17.9 percent) sees seawater desalination as the most
critical thing the authority could do to secure water supplies than those who
believe the answer is using recycled water (3.7 percent)." In regards to saving
water, "more residents said they'd save water by cutting indoors," such as
taking shorter showers, than outdoor options such as "cutting irrigation."
Florida Utility Considers Desalination Project.
The Florida Times-Union (4/22, Hunt) reported, "Northeast Florida could be
tapping the Atlantic Ocean for drinking water within the next two decades,"
according to Kirby Green, executive director of the St. Johns River Water
Management District. The article noted that desalination is "one of the more
sensitive areas for JEA (Jacksonville Electric Authority) customers," who "are
facing rate hikes of about 45 percent - roughly 10 percent annually over the
next four years." Also, "building a desalination plant would make for a hefty
capital investment at a time the utility's water and sewer debt - $2.4 billion -
is projected to go into default if revenues don't increase."
Florida Utility Considers
Desalination.
The Florida Times-Union (4/22, Hunt) reports on the possibility of using
desalination to make use of Atlantic Ocean water in Northeast Florida. Kirby
Green, executive director of the St. Johns River Water Management District,
said, "It's not a question of 'will it happen?'" adding, "it can take seven to
12 years to get a desalination plant going." JEA CEO Jim Dickenson said that
"the utility should still ask customers to cut back on water use when they can,"
in order to "protect groundwater and avoid the need to build desalination
equipment." JEA customers "are facing rate hikes of about 45 percent -- roughly
10 percent annually over the next four years," while the utility "has released
one estimate suggesting that preparing seawater for household use could carry 12
times the cost of conventional groundwater." That estimate is presented as
questionable, but JEA spokeswoman Gerri Boyce said that the figure "includes
one-time plant construction and engineering estimates on a plant capable of
producing 15 million gallons daily."
Interior Secretary Calls For
Modernization Of California Water System.
The AP (4/16) reports, "Interior Secretary Ken Salazar urged California on
Wednesday to modernize its antiquated water system," and pledged "$260 million
in federal stimulus money to help finance projects aimed at relieving the
state's water woes." The Interior Secretary noted "California's massive system
of reservoirs, pumps and canals, built a half century ago, was designed for a
population half the size of the state's 37.7 million." The Sacramento-San
Joaquin Delta, "which provides water to nearly two-thirds of all Californians,
has become a highly troubled resource. Three years of below-average
precipitation have wreaked havoc on its habitat and water supply. Urban and
agricultural pollution are problems."
According to the Los Angeles Times (4/16, Chong, Boxall), $40 million of the
money will go "for groundwater pumping and other projects to ease effects of the
drought. Salazar also announced a "$29.4-million budget for improving the
national and international earthquake monitoring network," saying, "With nearly
75 million Americans living within earthquake-prone areas, this investment is
long overdue." An official "who coordinates the Advanced National Seismic System
for the U.S. Geological Survey," said that roughly "two-thirds of the money will
go toward modernizing seismic networks across the United States." The New York
Times (4/16, A19, Barringer, McKinley) also reports the story.
California Area Studying
Desalination Sustainability.
The Santa Cruz (CA) Sentinel (4/13, Bookwalter) reported on a "yearlong pilot
project commissioned by the Santa Cruz and Soquel Creek water districts to learn
if desalination is an option for the water-starved agencies." At the end of the
project, later this week, "water will stop flowing through various tubes and
membranes at the Long Marine Lab desalination plant," and also "tanks will be
taken apart, pipes dismantled and the building the plant stands in will be torn
down." While final conclusions "are still weeks away, Santa Cruz water chief
Bill Kocher deemed the experiment a resounding success," and said "the quality
of desalinated water provided by the small treatment plant justifies moving
toward a larger, permanent plant that, at its peak, could churn out 2.5 million
gallons of fresh water per day."
Florida Water Utility Makes Last
Withdrawal From Near-Empty Reservoir.
The St. Petersburg (FL) Times (3/14, Pittman) reported that as of last week,
"Tampa Bay Water has virtually drained its 15 billion-gallon reservoir. From now
until the summer rainy season, it must rely on its two remaining sources of
water: its sometimes troubled desalination plant and the dwindling supply in the
underground aquifer." According to the article, "the regional utility expects to
again ask the Southwest Florida Water Management District to impose the toughest
watering restrictions in history on Pinellas, Pasco and Hillsborough county
residents." The Times noted, "The reservoir, which covers about 1,100 acres in
rural Fort Lonesome, is normally
filled with water from rainfall, the Hillsborough and Alafia rivers and the
Tampa Bypass Canal. But an ongoing drought, which started three years ago, has
left all those sources depleted."
Taxpayers Association Opposes Desalination Project.
The Marin (CA) Independent Journal (3/5, Crane) reported, "Marin United
Taxpayers Association (MUTA) steadfastly opposes building a large permanent
desalination plant near the Central Marin Sanitary Agency plant in San Rafael."
The MUTA argued that "going high-tech environmental for fresh water in Marin
when other options are available during a period of wartime and downward
spiraling economy is irresponsible." The association "believes that using less
water -- is the cheapest, fastest and most ecologically friendly way to stem
Marin Municipal Water District's identified water shortfall of 6,700 acre-feet
per year by 2025."
