  • The gradual decline of farming activity during the 1950s and the importation of water to Southern California slowly transformed the Olivenhain area into a residential community

  • OMWD was Incorporated on April 9, 1959 in order 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 and the Metropolitan Water District of Southern California

OMWD: RECENT FACTSSunday, August 8, 2010 “NCT”LOCAL VIEW: Water district right on drought move

The Olivenhain Municipal Water District, which also serves residents in the city of Encinitas, recently reduced its drought response from Level 2 to Level 1. That board's decision was based in large part on the fact that it has a significant new supply of recycled water that will reduce its imported water use.

Residential and commercial customers served by OMWD do not pay less for water than SDWD customers, now that they are at Level 1. The assumption has been made that rates are now lower in OMWD.

SDWD's average residential customer's (bi-monthly usage of 30 units with a 3/4-inch meter) bill is $123.02. Our average customer would pay $124.86 if they were in OMWD.

Omwd recent facts


For commercial customers, OMWD's rate is $3.03 per unit and moves to $3.84 if the customer goes over the allotment (the allotment is based on meter size). SDWD has one rate for commercial customers ---- $2.92 per unit.

Even though SDWD will continue to charge a demand offset fee for new water meters, a meter does not cost more in SDWD than OMWD. As with rates, there are many factors that go into establishing a meter fee, so direct comparison with another agency doesn't always tell the whole story.

Comparisons between the San Dieguito and Olivenhain water districts and assumed that when Olivenhain went to a Level 1 and rescinded its "water demand offset fee" ($4,500 for a new single-family dwelling), that a new meter in OMWD would cost less. SDWD will continue to collect a potable water demand offset fee of $1,885 for a single-family dwelling and the base capacity fee for a 3/4-inch meter is $3,300, for a total of $5,185. OMWD's capacity fee ranges from $6,277 to $11,853.
