Water Supply

To view the journey of CVWD's water, view our Where Your Water Comes From educational video. 

CVWD’s drinking water comes from two primary sources: local groundwater and imported water. CVWD manages its supply and demand with careful analysis regarding customer need and population estimates to ensure there will be an adequate supply of clean, reliable water into the future. CVWD, like most other agencies, creates a Water Supply Master Plan every few years that helps guide our operations and water supply investments.

CVWD has a diverse water supply portfolio that helps us decrease our dependence on imported water. Finding new sources of water is critical to ensuring water supply reliability for our customers. CVWD has been building a network of wells to take advantage of local groundwater supplies. This helps to ensure reliability at a reasonable cost. The District's diversified supply ensures a reliable water supply during times of drought, regulatory constraints and other emergencies. CVWD maintains 34 reservoirs with a total capacity to store 95 million gallons of water in our service area. Additionally, our diverse water supply portfolio helps to keep rates as low as possible.
