Board to hear competing desalination plans
http://www.montereyherald.com/mld/montereyherald/9261747.htm
Dueling desalination plans will enter a three-ring circus before the Peninsula water district board this week..

The Monterey Peninsula Water Management District, desperate for a water source to replace the Carmel River, will hear presentations from proponents of three desalination plants considered for coastal Monterey County, one in Sand City and two larger proposals for Moss Landing.

The major question facing the district is whether to pursue its own plant in Sand City -- an environmentally friendlier proposal, but one that would not solely solve the district's water problems -- or seek a partnership with one of the larger plants in Moss Landing.

The competition between those two proposals has provided some high drama this year that will no doubt increase in the months to come.

In a partnership with the county that has not yet been inked, the California-American Water Co. is proposing a plant that would use the intake and outflow pipes at Duke Energy in Moss Landing. It has identified three potential Moss Landing sites, including one on property owned by competitor Nader Agha.

Production capacity|

Steve Leonard, general manager of Cal-Am, said the plant is expected to produce 20,000 acre feet of water per year, the amount identified as necessary to fill the needs of the company's Peninsula rate payers, as well as the general plans of other jurisdictions in Monterey County.

Cal-Am is under state mandate to develop a new source of water to replace 10,730 acre feet it has been pumping illegally from the river annually for decades. An acre foot of water is enough to turn a football field into a foot-deep pond or to supply four average Peninsula homes for a year.

Cal-Am expects to have a pilot plant, producing 60,000 gallons of water a day, on the Duke property by next year. Until the water quality is tested, the water will be provided to Duke for production purposes.

Leonard said Cal-Am hopes to have the environmental impact report on the entire project ready for review by the fall of 2006, but he declined to estimate when the larger desalination plant could be online, or how much it might cost.

Cost estimate|

A cost estimate might be available by the end of July; as for a possible on-line target date, he said, "Five years is reasonable, but it's unpredictable."

One issue holding up progress may be the fact that Cal-Am and the Monterey County Water Resources Agency have yet to reach a formal agreement on their partnership.

Some critics of Cal-Am's proposal, including its competitors, have objected to a privately owned plant, especially one owned by a foreign company that might try to use international trade agreements to skirt local and state regulations.

Leonard said Cal-Am, a German-held company, has no intention of bypassing local regulations and every intention of building a desalination plant that will be publicly owned.

"We're working with the county to find a way where the county ultimately owns the plant," Leonard said. "We agreed that we are going to work toward an agreement and we have a draft going back and forth that we're nibbling and chewing on."

A county ordinance prohibits private ownership of desalination plants. The ordinance has never been tested legally.

Competitors|

Cal-Am's competitors, Agha and the Pajaro-Sunny Mesa Community Services District, have held up public ownership as an element that makes their proposal superior to Cal-Am's.

The Pajaro-Sunny Mesa district is proposing a plant at the site of the old National Refractories plant, which is now owned by Agha. The site is next door to Duke Energy and has its own intake and outflow pipes.

The plant would produce 21,000 to 25,000 acre feet a year, said district counsel Marc del Piero, and cost a total of between $135 million and $155 million for construction and water delivery.

Agha estimated the plant could be online in about 18 months.

Del Piero, a water use attorney and former State Water Resources Control Board member, has publicly warned various groups about the potential for foreign-held companies to use trade agreements to bypass local regulations.

Both he and Agha have touted their plan as a not-for-profit project to deliver water to the county for its 21st century needs.

"We think that controlling the water resources of Monterey County results in significant control of the economic viability of our county and we believe that is best left in the hands of the representatives of the people," del Piero said.

"Our heart and interest is in the community, not in profit," said Agha. "Water should not be abused and used to hold the users hostages for corporate bosses to fatten their pockets."

Leonard declined to enter the verbal fray, saying he didn't know if his project was better. But he touted the experience of Cal-Am's Spanish engineering firm, Pirdesa, which is owned by Cal-Am's parent company and has built many desalination plants around the world.

Del Piero said Pajaro-Sunny Mesa also is backed by a highly experienced engineering firm, Kennedy/Jenks, which also has built dozens of desalination plants.

One things is virtually certain, the California Coastal Commission and the Monterey Bay National Marine Sanctuary, both of which must sign off on any desalination plant on the bay, will approve only one desalination plant in the area.

Both of the proposals have environmental concerns not presented by the smaller Sand City plant that is favored by one of the district's directors, Kristi Markey.

While the Moss Landing plants would use huge intake pipes that kill virtually all marine life sucked in with the water, the Sand City plant uses beach wells and horizontal beach drilling to pull water from beneath the sand, thereby eliminating the "entrapment and impingement" problem.

In addition, the plant's capacity is so small that it doesn't present the growth-inducement problems that environmentalists fear in the larger plants.

The district had pursued the project fairly far down the environmental-review path, nearing the point where it would complete a draft environmental impact report, when the pro-growth-dominated board put it on the back burner.

Henrietta Stern, the staff member overseeing the project, said the district's new general manager, David Berger, wants to make a decision on which plant the district will pursue by September.

Just a bit of an fyi. :)

Company to let Water Authority visit desalination site
http://www.nctimes.com/article...ies/21_31_519_1_04.txt
SAN DIEGO ---- A private company studying the idea of turning seawater into drinking water at Carlsbad's Encina Power Plant has given county water officials permission to look around the site Friday.

The San Diego County Water Authority and Poseidon Inc. officials have clashed for nearly a year over the agency's desire to conduct environmental tests before signing a deal to let Poseidon build the plant for the agency.

Poseidon officials have said they're afraid the Water Authority would use the information to cut Poseidon out of any deal to build the plant.

The Water Authority could possibly do that by using environmental information to complete an environmental impact report ---- a report required before a plant can be built ---- and using its government powers to take the plant site from Poseidon and build the plant itself.

Poseidon, which is based in Connecticut, holds a 60-year lease on the Encina site and has been studying the desalination plant idea for six years.

On Wednesday, officials from both sides said they hoped the "no-testing, reconnaissance-only" visit Friday would thaw the chill between the agency and company ---- and possibly lead to an agreement to allow the Water Authority testing.

"We're taking them at their word that they want to make this work," Poseidon Vice President Peter MacLaggan said. "Where this goes from here is anybody's guess."

Water Authority desalination program manager Bob Yamada said Wednesday that the agency also viewed Friday's visit as a positive step.

"I think this is an important first step toward getting the (access) agreement done, providing us with a detailed scope as to what tests we want to conduct, and what time frame we're looking at for doing the tests," Yamada said. "To do that, we need to get on the site and look around."

The Water Authority and Poseidon spent three years negotiating the possibility of building a "regional" seawater desalination plant at Encina that could eventually turn 80 million gallons of ocean water into drinking water in a day.

The Water Authority board, which is made up of water officials from 23 major water agencies and cities in the county, has officially identified the proposed Encina plant as "critical" to the county's future water supply.

But Water Authority officials broke off negotiations with Poseidon in January after a prolonged dispute over environmental testing.

Poseidon officials said the environmental information the Water Authority wanted was confidential and protected because it amounted to their business's trade secrets.

But Water Authority officials said Poseidon wasn't protecting "trade secrets." The agency said Poseidon was using its confidentiality agreement to argue that "the very idea" of building a desalination plant at Encina was Poseidon's confidential information.

Water Authority leaders have said they could use their eminent domain powers to take the plant site from Poseidon "for the public good," if the company tried to get too much profit for building and running the plant.

Since January, Poseidon has been negotiating with the city of Carlsbad. The company and city officials said recently they've reached a deal ---- which still needs Carlsbad City Council approval ---- to build a 50 million-gallon-a-day plant at Encina.

However, Carlsbad can only use half of that water, meaning Poseidon still needs to find other partners ---- other cities or the Water Authority ---- to make that deal work.

In mid-August, Water Authority board members voted to resume negotiations with Poseidon and to seek immediate access to the Encina site. However, Water Authority leaders said they wanted access to the site before resuming the talks and would only resume partnership negotiations within 60 days after talking with city of Carlsbad officials about the deal.

Because of that stance, Poseidon officials said they wanted a written access agreement ---- presumably promising test information would not be used to support any eminent domain case ---- before letting the Water Authority conduct tests at the site.

I would imagine they would start towing icebergs down before they went too far with desalinization plants.

Texas is wanting to develop the first large scale coastal desalination center in the US. There are already funded desalination projects that are smaller in Brownsville, Corpus, and Freeport. Texas already operates 150 inland desalination centers, that produce 50million gallons of water per day. The major coastal desalination center is going to be pushed heavily come the 2005 session(Jan-May).

Poseidon is working with Dow on the Freeport Desalination project. It is set produce 100million gallons of water a day. The other two projects arent as far as long but are projected to produce 25million gallons of water a day.

The Fort Bliss Disalination project would be the largest inland desalination center pumping out 20million gallons a day.

There are legitimate ecological concerns with using seawater for power and drinking water generation. They're kind of complicated, unless you have a basic thermodynamics education, so I don't think it's really appropriate to go into here. I do think it's hillarious the way you state it though. :p

<BR><BR>There are environmental problems with it is why. The salt doesn't just disappear and you can't just dump it back into the ocean.
Municipalities around the country could use the salt rather than having salt mines. Increased supply would save citizens in colder climates quite a bit of cash.

Not true, we are sucking down the Lakes here in the Southeast too.<BR><BR>In fact to try and not drain it down so bad they are now dumping the sewage (all 85 millions gallons a day) right back into the lake (Lake Lanier) that we get our drinking water, isn't that special, drinking everyone's sh1t &amp; piss.
*shakes his head* That's just not the way it works. No water that is untreated, other than stormwater, may be emitted into a public body of water. The water that's going into the lake is much more likely to be cleaning the lake, rather than filling it with 'everyone's sh1t &amp; piss.' Public wastewater treatment plants are required to produce almost drinking-quality water in order to make up for all the contamination present in the bodies that they're dumping into in order to basically dilute the pollution. Further, the water from the lake is treated by drinking water suppliers prior to anyone drinking it.

Cheap desalination technology has been around, but hasn't been implemented due to the fact that it requires dumping the salt back in the ocean. Desalination requires high pressures, which can easily be achieved at the bottom of the ocean. Unfortunately, you're pressing water through filters, so the filters need replacement or cleaning. Cleaning using automation is possible, but then the salt just gets dumped back in the water. Replacing the filters at the bottom of the ocean just isn't very practical, for obvious reasons. Unless something pretty novel comes along, I don't see this technology hitting the big time unless we run up against a wall of not having water.

We have the capability to exceed them, but there is alot more bureaucracy in the US. Its alot easier to do something in a monarchy that also controls the worlds largest oil supply. Another factor is without thier thirty desalination plants they would be up sh!t creek.
