Olivenhain Municipal Water District (OMWD) is a member of the San Diego County Water Authority (SDCWA), and thus purchases all of its water supply from the SDCWA.  SDCWA in turn purchases its water from the Metropolitan Water District of Southern California (MWD). MWD is a wholesaler that provides water to over 17 million people living in Southern California . 

MWD imports its water from two sources: a 242 mile-long aqueduct which transports Colorado River water from Lake Havasu to Southern California and a 444 mile-long aqueduct that transports water from the Sacramento-San Joaquin Delta in Northern California to Lake Skinner located in Riverside Country.  The potable water is treated at the Robert A. Skinner Filtration Plant at Lake Skinner before delivery into the OMWD distribution system.

The David C. McCollom ultrafiltration membrane water treatment plant allows OMWD to purchase less expensive raw water and treat it locally. About 75% of OMWD customers receive a blend of water treated at the Skinner Filtration Plant and water treated locally.

OMWD is committed to protecting its water sources, and continually looks for ways to increase its local supply. Programs include groundwater basin studies, recycled water, watershed outreach and education, and joint projects such as the Olivenhain Water Storage Project.

We take great pride in providing quality water with quality service.  Whether its establishing new water services or checking for leaks, our friendly and courteous staff is available to serve you.  Stop by our offices or give us a call at 760-753-6466.
