On May 30, 2018, the Santa Fe Irrigation District and the San Dieguito Water District celebrated the San Dieguito Reservoir Dam’s 100 year anniversary and the dedication of the new San Dieguito Reservoir Pump Station.
Jointly owned by the Santa Fe Irrigation District (SFID) and the San Dieguito Water District, the San Dieguito Reservoir Dam (SDRD) and the San Dieguito Reservoir Pump Station (Pump Station) are important assets providing local water for over 60,000 customers in the North Coastal region of San Diego County.
Built in 1918, the SDRD was constructed in a mere four months in conjunction with the Lake Hodges Dam. Water was gravity fed from Lake Hodges through a flume to the SDRD to provide irrigation water to customers within the Rancho Santa Fe and Solana Beach areas.
Today, the San Dieguito Reservoir (Reservoir) continues to receive water from Lake Hodges, and is used to pre-treat the local water before being pumped to the R.E. Badger Filtration Plant (Plant) for treatment into drinking water for customers in the cities of Solana Beach and Encinitas, and the communities of Rancho Santa Fe and Fairbanks Ranch. The SDRD was evaluated in 2015 and found to be in very good condition and just reaching its mid-life with another 100 years of useful life.
The Pump Station was originally built in 1964 to convey raw water from the Reservoir to irrigation customers. It was upgraded just a few short years later, in 1967, at the same time that the Plant was being constructed. The Plant is a conventional drinking water plant that went into operation in 1970. At that time, the Pump Station began pumping the local water from the Reservoir to the Plant for filtration and delivery to customers. By 2015, the Pump Station had reached the end of its useful life and required replacement. The new Pump Station was completed and began service in September 2017.
“The pump station at the reservoir is a part of our local water supply system that we have continued to improve throughout the years,” said SFID Board President, Michael Hogan, “and it has been an important asset from the beginning for ensuring customers of our two districts have high-quality water.”
The celebration on May 30th included both the recognition of the SDRD’s 100 year anniversary and dedication of the new Pump Station with a ribbon-cutting.
