General District Information
Western supplies water on both a wholesale and a retail basis to a region stretching 527-square miles in western Riverside County with an assessed valuation of $83 billion and a population of more than 880,000 people. This regional area includes the cities of Corona, Norco and Riverside and the water agencies serving Box Springs, Eagle Valley, Lake Elsinore, Temescal Valley and Temecula.
We are governed by a Board of Directors, elected to four-year terms by registered voters in the five election divisions.
Western is staffed by approximately 140 employees who represent a variety of divisions of the District - engineering, finance, operations, water resources and administration. The District is managed by Craig Miller, who also acts as its court-appointed watermaster, and the management team.
While most of Western’s business is in wholesaling of water to water agencies and municipalities, the District directly serves approximately 25,000 residential and business customers in the following areas:
- Riverside - home to Western’s largest grouping of direct customers. Areas served include a portion of the city of Riverside, Orangecrest, Mission Grove, El Sobrante, Eagle Valley, Woodcrest, Lake Mathews, portions of Mead Valley and Perris, and March Air Reserve Base.
- Murrieta - with the merger of the city’s water utility agency in 2005, Western now serves a 6.5-square mile section of western Murrieta, primarily in the historic downtown area of the city.
- Rainbow - Western’s most distant served community is an unincorporated area of southern Riverside County bordering San Diego County.
Western currently sells approximately 85,000 acre-feet of water annually. This is equal to about 28 billion gallons of water. One-quarter of Western's sales are to retail customers; three-quarters to wholesale. About two-thirds of the water Western sells is treated; the balance is untreated or raw water. About one-quarter of water sales are for agricultural uses; the balance is for domestic purposes. Nearly all water sold by the District for agricultural purposes is used to irrigate citrus and avocados planted since the 1950s.
