Delta Water Supply Project

Delta Water Supply Project

The Delta Water Supply Project (DWSP) is a new supplemental water supply for the City of Stockton Metropolitan Area (COSMA). The City seeks to secure a long-term supplemental surface water supply to use conjunctively with its local groundwater resources and other existing surface water sources. The City has applied to the State Water Resources Control Board (SWRCB) for a water rights permit to divert water from the Sacramento-San Joaquin Delta. The City's water rights application addresses a long-term planning horizon through the year 2050, requesting an ultimate diversion to 125,900 AF/year. Proposed DWSP facilities include: a new water intake facility on the southwest tip of Empire Tract on the San Joaquin River, transmission pipelines along Eight Mile Road and other city streets to connect to the existing water distribution system, and a water treatment plant (WTP), located on Lower Sacramento Road just north of the current City boundary. The DWSP would be implemented in phases as the need for additional treated water supply develops. This environmental document provides a project-level evaluation of the initial DWSP (30 million gallons per day (mgd) or 33,600 acre-feet per year) and a programmatic review of the entire DWSP program, with an ultimate treatment capacity of XXX mgd (125,900 acre-feet/year). After the initial phase the City will consider the need to include an Aquifer Storage and Recovery (ASR) component in the DWSP to actively recharge the groundwater aquifer and optimize use of Delta water in periods when supply exceeds demand. The first phase of the DWSP is designed to meet the treated water supply needs of full urban development (build-out) under the City's current 1990 General Plan, which is anticipated to occur by about the year 2015.
