- Document Description
- Currently, the City's primary sources of untreated water are the San Joaquin River (River) and water purchased from the Contra Costa Water District (CCWD) via the Contra Costa Canal. The City currently pumps River water to the City's municipal reservoir then to the water treatment plant (WTP) located at 401 Putnam Street, Antioch. Because the Antioch WTP does not reduce chloride concentrations, the City stops pumping River water when the chloride concentration in the municipal reservoir approached levels that are too high for public consumption, typically around 75 milligrams per liter (mg/l). The City purchases water from CCWD when it is unable to utilize River water. Generally, the City is able to use River water from January to July, and relies on water from CCWD for the Remainder of the year. The City proposes to construct, operate, and maintain the Project which includes a 6 million gallons per day (mgd) desalination facility within the City's existing WTP. The goals of the project are to improve water supply reliability and water quality for its customers, especially during droughts and future changes in Delta water management, and to provide operational flexibility for the City. The project meets these goals by constructing facilities that allows the City to withdraw water from the River year-round under its pre-1914 water rights, even when the chloride concentration is above the 75 mg/l limit normally treated at the WTP.
