The Santa Margarita Water District imports its domestic water supply and is committed to its customers to plan and develop water infrastructure facilities to protect and enhance local supply reliability.
In response to this commitment, SMWD has constructed the Upper Chiquita Reservoir to provide the region with substantial new water reserves to meet customer demand during disruptions of water deliveries to the District. These interruptions can be unanticipated, like the break of the District’s primary supply pipeline in 1999, or planned, like the recent shutdown of the Diemer Filtration plant in Yorba Linda.
The Upper Chiquita Reservoir is located on the western slope of Chiquita Canyon, just north of Oso Parkway in the City of Rancho Santa Margarita. Completed in October 2011, the 244-million gallon Upper Chiquita Reservoir is the largest domestic water reservoir built in south Orange County in nearly 45 years.
