The Carlsbad “Bud” Desalination Plant is a water treatment facility located in Carlsbad, California, in San Diego County. Completed in 2015, it serves to deliver around 8-10% of the county’s total water supply, and some of the only water that is not imported.[1]

Narrative edit

In response to continual droughts in the region and growing concerns with regard to water security, several counties have experimented with water desalination since the 1990’s. Poseidon, the developer and manager of the Carlsbad “Bud” Lewis Desalination plant, first partnered with the San Diego Water Authority in 1998 with the plans of developing sustainable water security for San Diego’s future, with a few ideas for the plant.[2]

The RFP was first issued in 2006, and before bidding even ended, the project, as well as many other projects throughout the state, received massive setbacks in the form of fourteen different lawsuits placed against construction. This was before any of the many environmental and regulatory approvals could be processed.  Most of these suits were filed from the Surfrider Foundation’s San Diego chapter[3] with most of their and interested group’s main objections being environmental in nature. Even since the plant’s completion in 2015, groups such as Sierra Club have criticized the re-entry of brine extracted from the water back into the ocean, increasing the average salinity of the water, as well as putting in danger species which lay eggs and microorganisms which live where the water is extracted[4]. They have also echoed the popular expectation that the plant would account for more than just 8-10% of the San Diego water supply, not to mention that 90% of the remaining water balance is exported from the Colorado river.[5]

Trouble did not end at the lawsuits, however. The San Diego Water Authority broke away from planning and constructions obligations in 2006, leaving Poseidon to fend for itself in terms of construction. Poseidon did eventually find a site for construction, however, next to the Encina Power station in Carlsbad.

Despite these objections, the plant’s designs and concepts still eventually gained approvals and awards to begin construction in 2009. In 2011, after a lengthy legal battle, the California supreme court upheld lower-court rulings in favor of the plant’s construction. Objections among interest groups continue elsewhere for similar plants throughout California, but most recently, the California Coastal Authority overturned their long-standing refusal of such a facility in Orange County[6].

The plant finished construction in 2015, and on average, adds $5 to the cost of water in San Diego. While both the San Diego Water Authority and Poseidon have vowed to bring its cost down, as of 2021, it is still some of the most expensive water-per-gallon that exists[7]. Other outlets have also echoed the sentiments of the Sierra Club and Surfrider Foundation. A production shortage of 9,200 acre feet of water caused the SDWA to issue $3.5 million penalty in 2017. This is, however, coupled with the $97.5 million the SDWA owed to Poseidon from water that the county did actually receive[8]. That said, even the more critical outlets cite the plant’s ability to produce more water than designed, sometimes at 53 million gallons daily, compared to the 50 million target.

Desalination edit

Desalination is the process by which salt water, or otherwise salinized water, is converted into fresh water. The process by which the Carlsbad Plant achieves this is highly technical.

The process begins by extracting salt water from the ocean in the San Diego area. This used to be done by the Encina Power Plant next-door to the Carlsbad plant but is now done completely internally by the Carlsbad plant. The water is then filtered traditionally through filters to get out larger material and marine life, like algae and plankton, in addition to larger materials. After that, the water is then processed through a long series of membranes, through long tubes throughout the facility, in which the water flows. In these, “reverse osmosis” occurs, where the membranes have thin enough holes to where water can pass through, but salt cannot as easily. After many layers, the salt is eventually separated from the non-diluted water. These membranes also catch viruses and bacteria, further purifying the water. The leftover materials are then put back into the sea. The distilled water is then treated with minerals, chlorine and then integrated with the San Diego water supply[9].

Project Bonds[11] edit

The Project Bonds are being issued to fund the majority of the costs of acquiring, constructing and installing a desalination project (the “Project”) to supply potable water (“Product Water”) to the San Diego County Water

Authority (the “Water Authority”).

Bond issuer: The California Pollution Control Financing Authority to pay a portion of the cost of constructing a reverse osmosis desalination plant (The “Plant”) and a pipeline to connect a plant (the “Pipeline”), together the “Project”.

The Series 2012 Plant Bonds will be issued as term bonds in the aggregate principal amount of $530,345,000 and will mature as shown in the Table 2.

The Series 2012 Pipeline Bonds will be issued as term bonds in the aggregate principal amount of $203,215,000 and will mature, as shown in the Table 3.

The Project Bonds will be issued pursuant to separate trust indentures and the Issuer will lend (a) the proceeds of its Series 2012 Plant Bonds to the Company to pay a portion of the costs of constructing the Plant and (b) the proceeds of the Series 2012 Pipeline Bonds to the San Diego County Water Authority Financing Agency (the "Water Authority Financing Agency") to pay the costs of constructing the Pipeline pursuant to separate loan agreements. The Water Authority Financing Agency will make the proceeds of its loan available to the Water Authority under an installment sale agreement.

 
Construction Entity Structure

The Water Authority will make installment payments to the Water Authority Financing Agency, which will be the sole source of payment of the Water Authority Financing Agency's payments to the Issuer under its loan agreement. The Water Authority will not be obligated to make any installment payments unless and until the Project is completed. A capitalized interest account will be established for each issue of Project Bonds that will be funded from the related bond proceeds in an amount sufficient to pay interest on the related Project Bonds for six months after the date by which the Company's contractor has guaranteed to complete construction of the Project.

 
Outline of relationships to SPV for Carlsbad Plant

If the capitalized interest account for the Pipeline Bonds is depleted prior to completion of construction, the Company must pay delay damages to the Water Authority in an amount sufficient to pay debt service on the Pipeline Bonds until completion. The contractor will have a corresponding obligation to the Company up to a maximum amount. During operations, the Company must pay performance damages to the Water Authority for its failure to deliver Product Water to the Water Authority in accordance with the terms of their water purchase agreement. The Water Authority's obligations to make installment payments will be reduced by the amount of such performance damages, whether or not paid. The Water Authority Financing Agency's obligation to make loan repayments will be reduced by the amount of such performance damages, whether or not paid. The Water Authority has assigned its right to receive both delay and performance damages to the Water Authority Financing Agency to secure its obligations under the installment sale agreement, and the Water Authority Financing Agency has, in turn, assigned its rights to receive such damage payments to the trustee for the owners of the Series 2012 Pipeline Bonds. The Company's obligations under the loan agreement for the proceeds of the Series 2012 Plant Bonds and its obligations to pay delay damages with respect to the Pipeline will be secured on parity with the Collateral described herein. The Water Authority's obligations to make installment payments are unsecured but will have the benefit of certain covenants, including a rate covenant, made by the Water Authority in respect to its secured debt.[IVT1]

The Project Bonds are limited obligations of the issuer and neither the faith and credit nor the taxing power of the State of California. The Issuer has no taxing power, which means that the issuer promises to pay back the money they borrowed when they sell these bonds. But, State of California or any local government isn't guaranteeing that payment. So, if the issuer can't pay, the state won't step in to cover the bill. The issuer also can't raise taxes to gather the funds.

Takeaways edit

The Carlsbad “Bud” Lewis Desalination Plant has undergone a tremendous number of hurdles to achieve full operational capacity. It is an example of how lack of trust within technological infrastructure development can lead to delays for P3 projects, and how studying the success and full story of a P3 comes from a full understanding of the political context surrounding creation, rather than just financial analysis. However, its pioneering technology and essential nature brings its success under more scrutiny. Following Poseidon’s contract to its conclusion will prove essential for future, similar projects elsewhere in California especially, due to their continuing drought. Its lack of success in the eyes of its detractors and somewhat unaddressed environmental concerns has delayed other projects, like in Orange County, from State-Level authority. But if their eventual acceptance of a desalination project is anything to go by, even non-P3 endeavors will likely enter the news soon.
