After reading this page, we hope you will have a clearer high-level idea of where your water comes from and how it travels from our water treatment plants to your home. If you are interested in even more detail, click some of the links below that take a closer look at the facilities and processes we use to get your water to you safely and reliably.

Let’s start with the basics first.

For people living east of Silva Valley Parkway in El Dorado Hills—in places like Cameron Park, Shingle Springs, Diamond Springs, Placerville, Camino, and Pollock Pines—your water comes from what we call our eastern supplies. Much of this water is stored in Jenkinson Lake (Sly Park) and is treated at our Reservoir A Water Treatment Plant near the lake in Pollock Pines, and then travels through 1,300 miles of pipes to reach your home.

If you live in El Dorado Hills, most of your water comes from Folsom Lake. This water is pulled from the lake using EID’s recently replaced Folsom Lake Intake to the nearby El Dorado Hills Water Treatment Plant where we treat it before it is distributed to the community. Sometimes El Dorado Hills residents get water from our eastern supplies, especially in summer when demands are high. It’s all part of our integrated, interconnected system.

All of this water starts as snow in the Sierra Nevada Mountains. EID’s supplies are all surface water. When the snow melts, it flows into rivers and we move some of it into reservoirs like Jenkinson Lake or our hydroelectric project (Project 184) that makes electricity. This hydro project not only produces electricity that we are under contract to sell to Pioneer Community Energy, it also provides one-third of our water supply.

Your water comes from pristine surface-water sources in the Sierra Nevada. State-certified treatment operators make sure it meets stringent water quality levels before it flows through EID’s intricate and interconnected system of pipelines and facilities to get to your taps.

However, there is much more to know about our water. We are excited to share with you additional details about:

• Treatment Processes: You can take a virtual tour through our Reservoir A and El Dorado Hills water treatment plants.
• Water Rights: This is why we’re allowed to take water and how much we can take. [Coming Soon!]
• Distribution System: Learn about our more than 1,300 miles of pipes and facilities that move the water through our beautiful, hilly landscape. [Coming Soon!]
• Integrated System: See how our entire water system works together to deliver water from one side of the area to the other, all powered by gravity. [Coming Soon!]
