THREE VALLEYS MUNICIPAL WATER DISTRICT

What THREE VALLEYS MUNICIPAL WATER DISTRICT does

Three Valleys Municipal Water District (TVMWD) is a wholesale water agency established by voter approval in 1950 (originally as Pomona Valley MWD; renamed in 1981) and headquartered at 1021 E. Miramar Avenue, Claremont, California. The district operates as one of 26 member agencies of the Metropolitan Water District of Southern California (MWD), supplying imported water — sourced via the State Water Project and the Colorado River Aqueduct — and treated water to 13 member agencies (cities, water districts, water companies, and educational institutions including Cal Poly Pomona and Mt. San Antonio College) across a 133-square-mile service area in eastern Los Angeles County, ultimately serving 525,000+ end consumers. Core assets include the 100% State Water Project-dependent Miramar Water Treatment Plant (treating over 20,000 acre feet per year, approximately one-third of treated-water needs), the 1987-built Miramar Water and Hydroelectric Facility with five generators (constructed for $30 million under a three-way partnership with the City of La Verne and Golden State Water Company), and an ELAP State-certified microbiology water quality laboratory. The district employs approximately 25 staff.

TVMWD's revenue model is anchored in wholesale water rates quoted per acre foot (325,851 gallons): untreated water at $912/AF and treated water at $1,395/AF effective January 1, 2025, scheduled to rise to $1,016/AF and $1,560/AF respectively on January 1, 2026 (with a $32 TVMWD surcharge embedded). Revenue is supplemented by annual fixed charges (based on historical imported water use, connected capacity, and meter count) and pass-through capacity charges imposed by MWD. Distribution is exclusively wholesale — TVMWD does not serve retail customers directly. Capital planning is conducted through an active Capital Improvement Plan, a five-year-cycle Regional Urban Water Management Plan, and a USBR-approved Regional Drought Contingency Plan. Governance rests with a seven-member elected Board of Directors, with executive leadership led by General Manager/Chief Engineer Matthew Litchfield, P.E. (since January 2019), and a leadership team including a Chief Administrative Officer, Chief Finance Officer, Chief Operations Officer, Chief Water Resources Officer, IT Manager, and HR/Risk Manager.
