EVALUATION OF SEAWATER DESALINATION PROJECTS<br />
PROPOSED FOR THE MONTEREY PENINSULA<br />
2.3 Sand City <strong>Desalination</strong> Project (MPWMD)<br />
Project name:<br />
Proponent(s):<br />
Location:<br />
Purpose:<br />
Sand City <strong>Desalination</strong> Project<br />
Monterey Peninsula Water Management District<br />
The desalination plant would be constructed at one <strong>of</strong> three potential<br />
sites within the City <strong>of</strong> Sand City. <strong>Seawater</strong> collection wells would be<br />
located within the City <strong>of</strong> Sand City and on former Fort Ord lands.<br />
Brine disposal would be through beach wells (radial wells and/or<br />
horizontal directionally drilled wells) in former Fort Ord or via the<br />
Monterey Regional Water Pollution Control Agency outfall north <strong>of</strong><br />
Marina.<br />
To assist CAW with development <strong>of</strong> a legal water supply to meet the<br />
provisions <strong>of</strong> the State Water Resources Control Board Order<br />
No. 95-10, and to <strong>of</strong>fset a portion <strong>of</strong> the Seaside Groundwater Basin<br />
overdraft.<br />
Production volume:<br />
8,400 ac-ft per year (7.5 mgd)<br />
Key features: 1. <strong>Seawater</strong> collection through horizontal directionally drilled (HDD)<br />
wells and/or radial wells located along the beach in Sand City and<br />
the former Fort Ord.<br />
2. <strong>Seawater</strong> collection manifold pipeline through city streets.<br />
3. Return water discharge will return concentrated seawater brine to<br />
the ocean via beach wells or the Monterey Regional Water<br />
Pollution Control Agency outfall north <strong>of</strong> Marina.<br />
4. Reverse osmosis (RO) process<br />
5. Post-treatment process<br />
6. Treated water storage<br />
7. Treated water pumping station<br />
8. Treated water pipeline<br />
