The Central Basin Division (Division) consists of three separate service areas. The Division serves approximately 26,600 customers in the Cities of Norwalk, Santa Fe Springs, Lynwood, Bellflower, Artesia, and Compton and in the unincorporated areas located in Southern Los Angeles County. Park does not expect any significant growth in number of customers.
Most of the water supply for the Division's three service areas is purchased from the Central Basin Municipal Water District (CBMWD), a subagency of the Metropolitan Water District of Los Angeles (MWD). The remainder is obtained from 15 company-owned wells.
Also, Park serves recycled water for non-potable purposes, primarily irrigation.
