County water authority deep-sixes seawater desalination plan
By: GIG CONAUGHTON - Staff Writer | ∞
SAN DIEGO ---- In an abrupt move Thursday, San Diego County's regional water supplier deep-sixed its dreams of turning seawater off Carlsbad's coast into drinking water, refusing to certify its own $1.8 million environmental study, and choosing to end five years of haggling with the private company studying the idea.
San Diego County Water Authority leaders Thursday said they were dropping any further pursuit of building a long-discussed plant at the Encina power station in Carlsbad that would turn 50 million gallons of seawater a day into drinking water for two reasons:
The decision by the Water Authority, however, does not mean that the $270 million plant will not still be built.
Poseidon, in a move to hedge its bets, had already reached a deal with the city of Carlsbad to build the plant in the event it could not reach a contractual agreement with the regional Water Authority.
Water Authority board members Thursday voted to "reconfirm" their commitment to help the city of Carlsbad in its quest to get the Encina plant built.
Board members and staff also said they would continue to investigate the possibilities of building their own seawater desalination plant at in South Bay and at the San Onofre Nuclear Generating Station ---- both of which are only in the earliest study stages.
Poseidon Vice President Peter MacLaggan, meanwhile, said after Thursday's meeting that the company was happy with the Water Authority's vote. He said it removed the confusion about who was involved in the desalination project and exactly what the project would be.
However, even though Poseidon officials disagree, the "local" Poseidon-Carlsbad deal could be more difficult to get off the ground than a deal between Poseidon and the Water Authority. Poseidon's deal with Carlsbad, which includes two other North County water agencies, would only use slightly less than three-quarters of the 50 million gallons a day that the proposed desalination plant would use ---- meaning Poseidon still needs to find other agencies to buy in.
Also, the California Coastal Commission, which must bless the proposed seawater desalination plant, has said it doesn't like the idea of private companies "controlling" public water supplies.
The Water Authority's decision to back away from the project came as something of a shock to observers.
The agency has publicly identified the Encina project as "critical" for the last three years, and spent five years negotiating with Poseidon.
Water officials said finding a way to extract salt from seawater to quench local thirsts had to be done because the region's population is outgrowing water supplies.
With little rainfall and reservoirs to store supplies, San Diego imports nearly all the water county residents use ---- from 70 percent to 95 percent ---- from two sources, the Colorado River and Northern California's State Water Project, which is suspect because of leaky levees.
Water Authority board member Bud Pocklington said during the meeting, "I guess I'm one of the most disappointed people here in this room today, because of all the years we've been working on desal.
"But desal," Pocklington said, raising his voice for emphasis, "has to be part of our (water supply). Take a look at what's happening in the Colorado River Basin. Of the last six years, five have been drought. Look at the north (California). One earthquake could wipe out our whole water supply."
The Water Authority's decision to back away from the Encina project came just days after it was reported that NRG Energy, Inc., the company that owns the Encina site, planned eventually to demolish the existing Encina plant.
NRG Western President Steve Hoffman said the company planned within three years to build a new power plant on the eastern portion of the 95-acre Encina site using "air-cooled" turbines rather than the current system ---- which uses seawater to cool turbines ---- and eventually tear down the plant that's currently being used. NRG also said that it planned to build its new plant exactly where the Water Authority wanted to build its desalination plant. Poseidon plans to build its plant on a different portion of Encina.
The Encina station, meanwhile, was considered perfect for the proposed seawater desalination plant because it already had environmental, regulatory approval to suck in seawater that could be desalted.
MacLaggan and Poseidon said even if Encina's generators eventually use air instead of seawater for cooling, the company would retain contractual control of the existing seawater intake and outflow system.
But Weinberg said the issue raised serious regulatory questions in the Water Authority's mind.
MacLaggan also said that Poseidon ---- unlike the Water Authority ---- was not surprised by NRG's news that it would reconfigure the Encina station, that Poseidon officials "always" assumed the plant could be shut down.
In related news, a coalition of environmental groups that filed a lawsuit a little over a week ago against the environmental study the city of Carlsbad created for its proposed Encina desalination plant ---- dropped the suit Thursday.
Lawyers representing the coalition would give no reason for withdrawing the suit. The lawsuit alleged that Carlsbad's environmental study did not do enough to show the harm the project would cause. The challenge argued that the desalination plant would significantly harm the ocean, marine life and marine ecosystems.
MacLaggan, who rejected the lawsuits' allegations, nevertheless said the company was happy to see it had been dropped.

I toured a plant once that was capable of making 3 million gallons of fresh water a day, that was 13 years ago. The technology is there but californians are too damn stupid and short sighted to make use of it. People like you with no concept of what you are talking about need to keep your mouth shut.
San Marcos Resident wrote on Jul 28, 2006 10:21 AM:The reality of the population growth the politicians, planners, and developers sold us on is slapping us in the face. Time to stop growth, require water-conseving measures, and if necessary, raise the price of water to enourage conservation. Sorry to say, folks, to all of you who supported this rampant growth, toilet-to-tap is in our future. Those of us who find that disgusting can buy bottled water. The rest of us will be drinking and filling our pools with it. "Smart growth"? That's just a ruse to keep the money rolling in to a select few, and the rest of us paying the price.
Hank wrote on Jul 28, 2006 1:02 PM:Hey San Marcos...it's cool to stop growth since you're here, right? Well, that won't happen. It may be awhile before recycled water makes it into the drinking water system, but even if/when it does, the bottled water producers will use it too! I think desal is the wave of the future, and it will definitely cost more.
To Mike wrote on Jul 28, 2006 5:39 PM:I agree with the second guy who called you a fool. Desalination plants have been around for many years working very successfully. You can only stop growth if you shrink the population by not having kids and make people die at an earlier age. The reality is that growth will always be with us. Our water districts have been fighting for years to make sure we get water from the North and from the Colorado river. Someday that might trickle to a stop and then what?
CC wrote on Jul 28, 2006 9:28 PM:I was a big supporter of desalinazation until I read an article that said we have dead zones all around the current desal plants that are located on our coast. Another problem is due to our trade agreements which will allow others to own our water even if we don't want that. You can stop growth and US citizens have done it with much sacrifice. We are currently at zero population growth. All population growth is currently coming from immigration. If the Senate immigration bill passes, we could easily be looking at double the population in California in just 40 years. This will place huge demands on our infrastructure. We currently allow 1 million legal immigrants per year. That allows for a modest amount of growth. But, the Senate bill will result in an absolute explosion in our population. We have sacrificed so that there will be enough water, roads, energy, wildlands, jobs, etc. to go around. But, apparently this sacrifice was to no purpose. US population is currently 300 million. It is estimated that the Senate bill will result in 100 million new legal immigrants over the next 20 years. In 40 years, one could extrapolate the numbers to 200 million more immigrants. Plus, immigrants have a higher birth rate than US citizens. Add to this the huge growth in illegals that will expect future amnesty. Add to this the general migration of the US population to the coasts, and you've got a huge population explosion in California. We better get busy building more roads.
MrP wrote on Jul 30, 2006 1:40 PM:I agree mostly with CC's comments. Not just with water supplies but indeed with all community needs (roads, education, health care, energy, gas, etc.) we are treating the symptoms and not the problem. The problem is overpopulation. We have simply outgrown the ability to meet reasonable needs. Frankly, conservation efforts are counterproductive. The more we save, the more is available to fuel growth. The savers are the ones that suffer through more congestion and demand for reduced services and higher prices for their efforts. Business and industry must figure out ways to prosper without growth. Developers, with the government at all levels as its ally, are choking us . . . snuffing out the Califiornia Dream. We could start by modifying our current taxation system which currently rewards large families through deductions. We need to look at a "China" model that would reward small families and not the large ones. Then there are those religions who promote large families . . . but don't get me started on that one.
