IID effectively delivers its annual entitlement of 3.1 million acre-feet, less water transfer obligations, to nearly one-half million acres for agricultural, municipal and industrial use. As part of its operating system, the district maintains an extensive gravity flow drainage system and 11 regulating/interceptor reservoirs. IID’s water service area contains seven cities (Brawley, Calexico, El Centro, City of Imperial, Holtville, Westmorland and Calipatria), three census-designated places (Niland, Seeley and Heber), the Naval Air Station El Centro & two state prisons (Calipatria and Centinela).  Except for Niland, Calipatria and Calipatria State Prison, which receive treated water from Golden State Water Company and Heber which is served by the Heber PUD, each municipal area operates its own water treatment plant.
