Olivenhain Municipal Water District (OMWD) is a public agency providing water, wastewater services, recycled water, hydroelectricity, and the operation of Elfin Forest Recreational Reserve.
OMWD is a municipal water district organized and operating pursuant to Water Code Sections 71000 et seq., and was incorporated on April 9, 1959, to develop an adequate water supply for landowners and residents. On June 14, 1960, residents of OMWD voted to become a member of the San Diego County Water Authority, thus becoming eligible to purchase water transported into San Diego County via the massive aqueducts of SDCWA and its wholesaler, Metropolitan Water District of Southern California. At over 48 square miles, OMWD serves approximately 86,000 customers in Encinitas, Carlsbad, San Diego, San Marcos, Solana Beach, and neighboring communities.
