Santa Margarita Water District

Santa Margarita Water DistrictSanta Margarita Water District serves as the second largest retail water agency in Orange County. The District provides safe, affordable, reliable water and wastewater services to over 155,000 customers in Mission Viejo, Rancho Santa Margarita and the unincorporated areas of Coto de Caza, Las Flores, Ladera Ranch, Rancho Mission Viejo, and Talega.

Like many water districts in south Orange County, nearly all of the District’s water supply is imported from Northern California via the State Water Project and from the Colorado River via the Colorado River Aqueduct. Given that our region lacks a natural aquifer, the District continues to challenge itself to be resourceful and innovative about local supply and reliability. The District is engaged in a number of pioneering initiatives to diversify SMWD's water portfolio and reduce the community's dependence on imported supplies.

Santa Margarita Water District is committed to helping customers create and enjoy beautiful landscapes that accentuate their lifestyle and enrich our community. The District offers classes on landscape design and outdoor efficiency, rebate programs, custom landscape design services, and resources, like, for the do-it-your-self types.
