MF/RO Facility

The CAWD/PBCSD Reclamation Project (the project) is a cooperative effort involving the Carmel Area Wastewater District (CAWD), the Pebble Beach Community Services District (PBCSD), the Monterey Peninsula Water Management District (MPWMD), and the Pebble Beach Company (PBCo). This cooperative effort did not create a new or separate legal entity. Therefore, the Project is a proprietary (enterprise) fund of Monterey Peninsula Water Management District, the issuer of the Certificates of Participation which financed the Project’s first construction project.

The Project provides treated wastewater to irrigate golf courses and open space areas in Pebble Beach, which freed up potable water previously used for irrigation. The original Project involved the construction of a new tertiary treatment plant and laboratory facilities located on the site of the existing CAWD secondary wastewater treatment plant, the construction of a new reclaimed distribution system, including a 2.5 million gallon storage tank, and irrigation system improvements. Construction of the original Project began in January 1993 and was completed in October 1994. The tertiary treatment plant produces water which meets Title 22 standards specified by the California Department of Health Services, which is a quality acceptable for human contact

The Microfiltration/Reverse Osmosis (MF/RO) phase of the project, located at the CAWD plant site, began design in 2006 and construction was completed in 2009. The intent of the MF/RO phase is to reduce the sodium content of the tertiary reclaimed water from 150 mg/l to less than 55 mg/l to reduce the stress on the golf greens and eliminate the need for flushing the courses with potable water. The design capacity for the MF/RO is 1.5 million gallons with an expected blend of 80% MF/RO water and 20% MF water. The cost of the MF/RO phase was approximately $20 million.

The cost of the Expanded Project was financed through the sale of water entitlements owned by PBCo to residential property owners within Pebble Beach, currently at $250,000 per acre foot, which is subject to change. At June 30, 2009 approximately $26 million had been raised through these sales and interest. The funds from the sales were deposited in a restricted escrow account where they were invested in short-term federal government securities before being spent for the Expanded Project. All project costs in excess of those raised through the sale of Water Entitlements are being covered by the PBCo.
