The Refinery Recycled Water Exchange Project is a regional recycled water project with the Central Contra Costa Sanitary District and Contra Costa Water District. The project would consist of Valley Water partnering with the Sanitary District to design, build and operate a recycled water facility. The facility would provide Central Costa Water District with recycled water to for operations at two existing oil refineries. In exchange for providing recycled water for refinery operations, Valley Water would receive a share of Contra Costa Water District’s imported water from the Central Valley Project.
This project could provide up to 9,000 acre-feet* per year of water to Valley Water’s supply. However, this would increase reliance on imported water supplies. Valley Water and partners have been working on a feasibility study to evaluate the costs and benefits of this project.
*an acre-foot of water is 325,851 gallons of water, approximately the amount of water used by 10 people in a year
