Regional Seawater Desalination Project

Document Description: NOTE: Joint Lead Agencies. Extended review to end on January 10, 2011. The City and the SqCWD have partnered to implement the scwd2 Desalination Program. This program proposes a seawater desalination project to provide up to 2.5 million gallons per day of water. This water would help the SqCWD meet its water needs as it reduces its groundwater withdrawals of the overdrafted Soquel-Aptos area to prevent seawater intrusion, consistent with its Urban Water Management Plan Update and its Integrated Resources Plan, and would help the City of Santa Cruz Water Department (SCWD) meet the water needs of its service area during drought periods, as contemplated by both its Integrated Water Plan and its Urban Water Management Plan. The proposed desalination project would consist of: (1) a seawater intake structure, associated pump station, and conveyance piping; (2) a seawater desalination plant that would provide for pretreatment filtration, seawater reverse osmosis, post-treatment conditioning and disinfection, and solids handling processes and their associated support facilities; (3) a brine disposal and conveyance system; and (4) water supply delivery system improvements.
