EID employs highly skilled and trained professional staff to get the job done. Our service area covers more than 220 square miles and ranges from 500 feet to more than 4,000 feet in elevation. We have more than 1,245 miles of pipeline, 27 miles of ditches, 31 potable water storage tanks, seven potable membrane covered reservoirs, six raw water storage reservoirs, 37 pumping stations, and five water treatment facilities.

Meeting the ever changing and increasingly stringent regulatory requirements is a complex task that our staff achieves 24 hours a day, year round. Millions of dollars are invested in treatment plants and equipment to keep your water safe and reliable and meet those regulatory mandates.

Every year, in accordance with the State Water Resources Control Board and U.S. Environmental Protection Agency, EID provides a look into the testing and quality of your water.  You may go to our Water Quality Report webpage to learn more and view the reports for each of our three water systems.

With some water rights that date to just after the Gold Rush, EID has a history that starts before it was even officially formed in 1925. If you would like to learn more please read our history brochure.

Five of EID’s raw water storage reservoirs are utilized for recreation: Jenkinson at Sly Park Recreation Area, Caples, Silver, Echo, and Forebay. Jenkinson Lake, built in the 1950s, was purchased by EID in 2003 and allowed us to take control of the operational functions of the water reserve from the U.S. Bureau of Reclamation. Having this control gave EID the ability to save our water for our own communities’ use and paid off immensely during the recent historic drought.

EID also utilizes water to generate clean energy with a 21-megawatt hydroelectric powerhouse federally licensed as Project 184.  The powerhouse generates approximately six to eight million dollars in revenue each year. The project and its water come from four high-elevation raw water storage reservoirs/lakes: Caples and Silver lakes  along Highway 88 and Lake Aloha and Echo Lake located north of the Highway 50 corridor. The project also includes Forebay Reservoir where the water is transferred from the upper lakes before either being delivered to generate hydroelectric power, or for our Reservoir 1 water treatment plant for drinking water. Water that is utilized for power is then returned to the American River where it flows to Folsom Lake, at that point we can then pull the water again to be treated for drinking water at our El Dorado Hills water treatment facility—double the benefit to our customers.

The cost of a 12-ounce bottle of water at a local convenience store can be more than a dollar.  For that price you could drink 500 gallons of healthy tap water from EID! And , you know exactly where it came from and who's accountable for it's safety!
