EVALUATION OF SEAWATER DESALINATION PROJECTS
PROPOSED FOR THE MONTEREY PENINSULA
6.3 Sand City Desalination Project (SCDP)
The Sand City Desalination Project, proposed in 2002 by the Monterey Peninsula Water
Management District, was sized to provide a replacement supply to meet current water
production as limited by SWRCB Order No. 95-10 and to offset a portion of the overdraft of
the Seaside Groundwater Basin and is intended to serve only the CAW service area. Because
of the unique features of the well intakes, the project should be capable of expansion,
provided additional planning of the seawater intake system and distribution and collection
systems is performed, and providing trunk mains are constructed with this expansion in
mind.
Because the project would serve 40 to 70 percent of the supply contemplated for the
MBRSDP and the CWP, removing this large portion of the customer base could make the
other desalination projects uneconomic.
There are no disadvantaged communities in the project service area.
6.4 Seawater Desalination Vessel (SDV)
The Seawater Desalination Vessel (SDV) proposed by Water Standard Company is
envisioned as supplying water to the Monterey Peninsula, with the potential to serve a large
portion of northern Monterey County. Water from the project would be delivered to
MPWMD and CAW and to other customers within the Monterey Bay area. A limited
amount of proposed distribution system information has been provided by the project
proponents, and additional planning, analysis, and design would be required if the project
were to proceed.
The SDV, MBRSDP, and the CWP share the major customer base on the Monterey
Peninsula, and for practical purposes are mutually exclusive. That is, only one of these
projects would likely be built.
The larger contemplated projects could have beneficial water quality impacts to
disadvantaged communities in northern Monterey County.
