Providing high quality water and first class customer service have been at the core of our mission since we were established in 1955, and will continue to guide us in our operations. It’s why the Cucamonga Valley Water District (CVWD) was created 60 years ago: to provide a high-quality, reliable source of water to a growing region. The District provides drinking water to more than 190,000 residents in a 47 square mile service area. Water is a vital resource, requiring careful management to ensure the needs of present and future generations are met.
Since our inception, CVWD has been committed to not only water delivery but also to providing high value in all we do. CVWD takes ownership to look for innovative solutions-based ideas to improve our effectiveness and service to customers. From providing high quality water, to diversifying our water portfolio, and planning today for the water needs of tomorrow, we believe in going above and beyond to work efficiently and cost effectively while practicing good stewardship of natural resources.
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 36 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.
Approximately 48 percent of our overall supply comes from local groundwater wells in the Chino Groundwater Basin and the Cucamonga Basin, located hundreds of feet below the earth’s surface. Groundwater is pumped out through a system of wells maintained by CVWD, disinfected, flows into storage reservoirs, and ultimately makes its way into the distribution system to consumers. CVWD currently operates 20 groundwater wells throughout our service area.
