Founding Members

The Inland Empire Garden Friendly program was developed by the four major water suppliers of western Riverside and San Bernardino counties in California with cooperation from a university institute, conservation district and local botanic garden.

Eastern Municipal Water District

Since its formation in 1950, Eastern Municipal Water District has matured from a small, primarily agricultural-serving agency, to one whose major demands come from domestic customers.

Inland Empire Utilities Agency

Inland Empire Utilities Agency originally named the Chino Basin Municipal Water District (CBMWD), was formed in 1950 to supply supplemental water to the region. Since its formation, the Agency has expanded its areas of responsibility from a supplemental water supplier to a regional wastewater treatment agency with domestic and industrial disposal systems and energy recovery/production facilities.

San Bernardino Valley Municipal Water District

The San Bernardino Valley Municipal Water District was formed in 1954 as a regional agency to plan a long-range water supply for the San Bernardino Valley. It imports water into its service area through participation in the State Water Project (SWP) and manages groundwater storage within its boundaries.

Western Municipal Water District

Western was formed by the voters in 1954 to bring supplemental water to growing western Riverside County. Today, the District serves roughly 24,000 retail and eight wholesale customers with water from the Colorado River, State Water Project and groundwater.

Chino Basin Water Conservation District

Since its establishment in 1949, the Chino Basin Water Conservation District has actively protected and replenished the Chino Groundwater Basin with natural area rainfall and storm water discharge from the San Gabriel Mountains. The District’s service area includes the cities of Chino, Chino Hills, Montclair, Ontario, Rancho Cucamonga, and Upland.

Rancho Santa Ana Botanic Garden

Rancho Santa Ana Botanic Garden promotes botany, conservation and horticulture to inspire, inform and educate the public and the scientific community about California’s native flora. The Garden is devoted to the collection, cultivation, study and display of native California plants and to graduate training and research in plant systematics and evolution. Through all its programs, the Garden makes significant contributions to the appreciation, enjoyment, understanding and thoughtful utilization of our natural heritage.

Water Resources Institute

The Water Resources Institute is an academic partnership with the Southern California communities we serve driven by the vision that sustaining water resources rests on sound research, analysis and public policy collaboration.
