According to Tom at Water Desalination Report, Auaguest 23, 2010:
San Diego County Water Authority – at an emergency session last Thursday heard Poseidon say:
Representatives from Poseidon, the company planning to build the plant, said the project was “not financeable” at the moment, because there wasn’t enough money in the deal to pay off debts and to attract investors. The deal already includes a subsidy from Metropolitan worth $250 per acre-foot of water for 25 years. There are also certain triggers that allow Metropolitan to withdraw from giving the subsidy by a vote of its board.

Don’t be so desperate for water (meaning, green lawns, because we can easily conserve 50 MGD) that we saddle taxpayers with 30 to 40 years of immense expense when new desal technology will be so much more affordable in the next few years.

There is much interest, but little clarity on the cost of desalinated seawater in California and how it compares to other urban water management options.
To address this issue, this investigation collected general information along with costs and production records and cost projections for many prominent seawater desalination facilities and proposed projects in North America and California.
Along with many others, this included Tampa Bay, Carlsbad, Santa Barbara, and Marin. These four projects are described and evaluated as case studies in this paper.
Seawater desalination for $800 to $1,000 per acre-foot? Or more like $2,000 to $3,000 per acre-foot?
Some advocates of seawater desalination suggest marginal costs of $800 to $1,000 per acre-foot are now possible in California. However, despite a thorough investigation, this study found no evidence of seawater desalination facilities in North America producing water in that cost range. This study also found no credible evidence that new seawater desalination projects in California, given local conditions, could produce water in that cost range.
Given the best presently available technology, this investigation found realistic estimates of the marginal costs for seawater desalination in California will range from a minimum of about $2,000 to $3,000 or more per acre-foot of water produced. This compares to typically much lower marginal costs of well under $1,000 per acre-foot for most urban water conservation measures.
The Carlsbad project, at 50 MGD design capacity, is the largest presently proposed project in California and the most progressed within the permitting process. It is proposed by a private corporation, Poseidon Resources, and is subject to less cost transparency than public projects.
Since Poseidon Resources is seeking publicly subsidized funding and financing, and indicates a willingness to match the cost of existing water supply options, much interest is presently focused on the realistic cost of water produced by the proposed Carlsbad facility. This analysis evaluates the realistic cost of desalinated water for the proposed Carlsbad and other desalination facilities from which adequate cost records and projections could be obtained.
What Will Large-Scale Seawater Desalination Realistically Cost in California?
With limited exceptions, water agencies and private interests involved in seawater desalination appear reluctant to release verifiable marginal costs analysis for their seawater desalination projects. This has troubled many observers since marginal costs analyses form the basis of integrated water resources planning and rational decision making for water management plans and infrastructure investments.

I doubt that “cheap desal” will ever be an operative term; there are reasons why such things are empty phrases, like “the hydrogen economy” and “secondary treatment is not a perfect process”.
The reason water is the “universal solvent” is the extreme electric potential of its covalent bonding, asymmetrical due to the famous 108 degree angle of the H-O-H molecule. The relatively small water molecules surround and, literally, tear apart many organic and inorganic compounds that have weaker bonds.
Water is much more stable than other compounds due to the enormous energy given off in its formation:
2H2+O2=>2H2O+lots of heat energy (that’s why creating hydrogen is so expensive).
Ex nihilo nihil fit: There is nothing “for nothing” in nature!
Con men play on the gullible in propounding the glories of Hydrogen, whining that there aren’t enough fuel stations, for example, for this “amazing fuel”. But to get the powerful fuel, you have to run that equation in reverse; you need to put about 60 kWh of energy into making each 35 kWh of H2, not counting compression and storage, leakage and inefficiency.
Similarly, the dream of “undoing the universal solvent”, or making fresh water out of dirty water, requires undoing a powerful force, that binding power of the asymmetrical water molecule, which defines water chemistry. A microwave, for example, heats substances by intense vibration of the water molecule based on varying magnetic fields of that asymmetrical molecule.
About the only way to ensure pure water is the hydrologic cycle, where the sun evaporates water via heat, and the purified water vapor recondenses into rain.
