Western Municipal Water District

What Western Municipal Water District does

Western Municipal Water District (operating as Western Water) is a California special district and public municipal water utility founded in 1954 and headquartered at 14205 Meridian Parkway in Riverside, California. The district provides integrated water supply, wastewater disposal, and recycled water services across a 527-square-mile service area in Western Riverside County, serving nearly one million customers directly and indirectly through regional partnerships. As a public agency, it is governed by a five-member elected Board of Directors and operates on a non-profit cost-recovery basis under California Proposition 218 rate-setting requirements.

The district's core offerings include water supply distribution, wastewater collection and treatment, water resource management (groundwater desalting, regional water rights), and customer-facing digital services such as the My Western Water Portal, Water Budget & Cost Estimator, GIS Developer Map Portal, and a Virtual Tour of the water treatment journey. Technology infrastructure spans conventional water distribution and wastewater treatment networks, groundwater management systems, and an ongoing Smart Water Meter Replacement Program for improved metering accuracy. Operational scale and supply diversity are reinforced through the district's representation on the Metropolitan Water District of Southern California Board and partnerships with adjacent agencies including Eastern Municipal Water District, Elsinore Valley MWD, and Rancho California Water District.

Western Water's business model operates on a regulated public-utility basis, generating recurring revenue from tiered water service fees, sewer service fees, one-time connection and meter fees for new development, and grant-funded conservation rebate programs. The customer base spans residential households, commercial and industrial users, developers, contractors, and vendors, with dedicated service paths for educators and students through outreach programs including the Lois B. Krieger Grants and Solar Cup competition. Distribution of services occurs via the westernwaterca.gov website, in-person service at headquarters, phone-based customer support, and developer/contractor channels, supported by a 24-hour emergency response capability.

Direct peers

• Eastern Municipal Water District: Adjacent Riverside County water district explicitly named as a joint-committee partner. Serves the same general region with the same municipal water-and-wastewater model, making it the closest operational peer to Western Water.
• Elsinore Valley Municipal Water District: Riverside County municipal water district that Western Water actively funds through the Lee Lake Wells project. Operates the same integrated water-supply model and serves overlapping customer geography in the Lake Elsinore / Murrieta corridor.
• Rancho California Water District: Southern California municipal water district identified in Western Water's partnership list as a joint-committee partner. Provides water supply and wastewater services with a comparable service-area footprint and customer profile.
• Inland Empire Utilities Agency: Multi-purpose wholesale water agency serving the western San Bernardino County portion of the Inland Empire. Closely comparable regional wastewater and recycled-water operator with overlapping service-area dynamics.

Regional players

• San Diego County Water Authority: Wholesale regional water supplier with whom Western Water announced a 'landmark regional water partnership.' Same public-utility governance model and shared regulatory environment under California law.
• Orange County Water District: Southern California groundwater management and water-reuse district operating under California special-district law. Comparable mission (groundwater, recycled water, water reliability) without direct service-area overlap.
• Calleguas Municipal Water District: Ventura County wholesale and retail municipal water district serving Southern California under the same California Public Utilities Code framework. Comparable governance, rate-setting process, and integrated water/wastewater service model.

Broad incumbents
