FPUD became a charter member of the SD County Water Authority when it was formed in 1944, making it eligible to receive a portion of the Colorado River diverted by The Metropolitan Water District of Southern CA. Significant expansions of FPUD's service area took place in 1950 when it annexed the last remaining portion of the Fallbrook Irrigation District and in 1958 with the annexation of the area to the north of town. In 1968 an agreement was signed with the Federal Government to develop a two dam and reservoir project for the benefit of FPUD and the U.S. Marine Corps Base Camp Pendleton. The federally sponsored project was known as the Santa Margarita Project. In 1978, FPUD began getting water from the CA State Water Project. To meet growing demand, Metropolitan began delivering water to SD County from the State Water Project as well as the Colorado River. In 1990, the registered voters in the DeLuz Heights Municipal Water District dissolved their district and its entire service area was annexed to FPUD, adding 11,789 acres to FPUD's service area. In 1994, FPUD’s operations grew once more when the Fallbrook Sanitary District was dissolved and FPUD took over sewer service responsibilities within a 4,200-acre area of downtown Fallbrook. Today, the District provides imported water and sewer service to 35,000 residents living on 28,000 acres, with approximately 40% of the water used for agriculture. The District also produces about 1.5 million gallons of recycled water daily. FPUD's mission is to provide for the community of Fallbrook, now and in the future, a reliable supply and delivery of high-quality retail potable water service. And to see to the collection, and disposal, of wastewater and solids, consistent with the optimal use of recycled water in the most efficient and economical means possible.
