The Morongo Basin Pipeline is a 71-mile underground pipeline built by the MWA that brings water from the California Aqueduct in Hesperia to the Rock Springs Recharge site at the Mojave River in south Apple Valley and to percolation ponds in the Hi-Desert Water District (HDWD) in Yucca Valley. Water flowing through the pipeline is diverted to recharge ponds in an effort to reduce overdraft in the Warren Valley Basin. The Morongo Basin Pipeline was completed in 1994 and deliveries began in 1995. The pipeline was financed by MWA, the HDWD, the Joshua Basin Water District, the Bighorn-Desert View Water Agency, and the County of San Bernardino. Pipeline turnouts exist to eventually serve other areas in the Morongo Basin in addition to HDWD.
