About El Dorado Irrigation District
El Dorado Irrigation District can trace its history back to the first hand-dug ditches that transported water to prospectors in the mid-1800s, but the District was not formally organized until 1925 under the Irrigation District Act (Water Code §§ 20500 et seq.). We still hold water rights that date from the gold rush days (Pre-1914), and we continue to work on securing and maintaining reliable water supplies. Through negotiations with the U.S. Bureau of Reclamation and an Act of Congress, the District acquired Jenkinson Lake at Sly Park Recreation Area in late 2003. We have water service contracts with the Bureau and a water right for diversion from Folsom Lake that was awarded by the California State Water
Resources Control Board. Our customers’ needs are as broad-ranging as the area’s stunning natural diversity. We provide drinking water, wastewater treatment, and recycled water for homes, schools, churches, vineyards, orchards, parks, and businesses. We
own and operate a 21-megawatt hydroelectric power project that includes dams, four reservoirs, and 23 miles of flumes, canals, siphons, and tunnels. And we manage several outdoor recreation sites, including the Sly Park Recreat...ion Area
and a campground at Silver Lake. Today, the District’s facilities and delivery infrastructure serves our 40,000 water accounts and includes more than 1,200 miles of pipeline, 27 miles of ditches, 5 treatment plants, 36 storage reservoirs, and 38 pumping stations. The wastewater system, with nearly 20,000 accounts, operates 61 lift stations, 390 miles of pipeline and 4 treatment facilities. El Dorado Hills and Deer Creek wastewater plants produce an average of 2,500 acre-feet of recycled water for use in front and backyard irrigation at 4,900 homes, commercial entities, and public spaces. With just over 200 employees, we are one of the largest employers in El Dorado County. We serve a population of over 115,000 that has been steadily growing for many years.
