EXHIBIT 6-A
CAWD/PBCSD RECLAMATION PROJECT
PHASE II - SALINITY MANAGEMENT PROJECT (MF/RO)
DRAFT PROJECT SUMMARY AND CURRENT STATUS
The Carmel Area Wastewater District (CAWD) is undertaking a Project to improve the quality of recycled water for irrigation of golf courses and green space in the Del Monte Forest.
In 1994, CAWD completed the existing tertiary facilities at
it’s wastewater treatment facility located approximately 1/3 mile West of
Highway One on the South bank of the
In response, “Phase II” to the Reclamation Project has been initiated. Phase II is actually comprised of two separate projects. One project, administered/managed by the Pebble Beach Community Services District (PBCSD) consists of upgrading Forest Lake Reservoir and appurtenant treatment and connection facilities. This project will provide a substantial increase in the storage capacity of the Reclamation Project and allow the Project to meet the peak irrigation demand during the summer.
The CAWD portion of Phase II is consists of the decommissioning of certain components of the existing tertiary facility, modifications to the existing secondary treatment plant and the construction of advanced treatment facilities to include microfiltration (MF) and reverse osmosis (RO) that will replace the existing tertiary facilities. Through “blending” of MF treated water with MF/RO treated water, the final delivered product will have sodium concentrations of approximately 55 mg/l as opposed to the current recycled water concentration of approximately 150 mg/l. (By comparison, seawater has a sodium concentration of approximately 35,000 mg/l.) This higher water quality will meet the quality requirements of the Del Monte Forest golf courses and other open spaces.
The new facilities will be capable of producing an average of 1.5 million gallons of high quality recycled water per day and with storage at Forest Lake Reservoir, total annual recycled water available could be as high as 1,500 acre feet.
As of January 2006, Project design is proceeding with design completion scheduled for mid-February 2006. Project construction is scheduled to begin this summer with completion date estimated at November 2007.
