Providing High-Quality Services Since 1964
Santa Margarita Water District provides safe, reliable drinking water, recycled water and wastewater services to over 200,000 residents in nine unique communities: Mission Viejo, Rancho Santa Margarita, San Juan Capistrano, and the communities of Coto de Caza, Las Flores, Ladera Ranch, Village of Sendero and Esencia, and Talega in San Clemente. The District is the second largest retail water agency in Orange County, by area, and third largest by customers served.
Nearly all the District’s drinking water supply is imported from hundreds of miles away. Santa Margarita Water District is committed to reducing its dependence on imported water by investing in local, reliable, sustainable, and cost-effective water supplies for today and generations to come.
- Recycle 100% of the District’s wastewater by the end of 2019
- 30% of drinking water supply from local sources by 2030
- 6 months of drinking water storage by 2030
The Santa Margarita Water District provides our customers with quality water and wastewater service – maximizing human, environmental, and financial resources – to help guide South Orange County’s water and wastewater needs into the next century.

The Santa Margarita Water District (SMWD) was formed in 1964 as a landowner district (Section 35306 of the California Water Code) by a group of ranchers who wanted to create a reliable source of water for their cattle. The first neighborhoods of Mission Viejo had not been built yet, and SMWD provided water to more cows than people.
