General District information

The San Dieguito Water District provides potable (drinking) and recycled water to over 38,000 citizens in the communities of Leucadia, Old Encinitas, Cardiff, and portions of New Encinitas. The remainder of the city is served by the Olivenhain Municipal Water District. The San Dieguito Water District is a subsidiary district of the City of Encinitas. The city council also serves as the board of directors of the District.

For potable water, the District receives local runoff water from Lake Hodges and imported raw water from the San Diego County Water Authority. Both sources are treated at the R.E. Badger Filtration Plant located in Rancho Santa Fe. Treated water from the San Diego County Water Authority may also be delivered directly to the District.

District recycled water is tertiary treated wastewater from the San Elijo Water Reclamation Facility in Cardiff. Currently recycled water is used for the Encinitas Ranch Golf Course, landscaped traffic medians, homeowner association common areas, and parks.
