Hi-Desert Water District was established in 1962 to provide drinking water for a growing population in the Mojave Desert community, just north of what is now Joshua Tree National Park. In an area of 57 square miles, the District operates 16 storage tanks and 13 wells and maintains about 300 miles of pipeline to provide water and sewer service for nearly 24,000 people in the Town of Yucca Valley and an adjacent unincorporated area of San Bernardino County, California.
