The Folsom Lake Intake supplies raw water from Folsom Lake to the El Dorado Hills Water Treatment Plant (EDHWTP) where it is treated and then conveyed to customers in El Dorado Hills. The water supplied through this system is critical to provide reliable potable water especially during the warmer months when water demands increase dramatically.
The original intake was constructed in 1958 and additional pumps were installed in 1994. Both systems have reached the end of their useful life as constructed and have become increasingly unreliable in recent years. A temporary third phase was constructed in 2010 however the temporary pumps have since failed entirely.
In addition to reliability issues, the facility must be modified to allow selective withdrawal of water based on temperature in order to preserve the cold-water pool in Folsom Lake to help enhance downstream habitat for anadromous fish (i.e., salmon and steelhead). The temperature control device (TCD) is a requirement of EID’s contract with the U.S. Bureau of Reclamation to allow EID to access its full allotment of water rights, which will be needed as demands in El Dorado Hills continue to increase.
The Folsom Lake Intake is a critical component to EID’s raw water supply. It is EID’s sole source of water from Folsom Lake, which makes up approximately 1/3 of EID’s water supply. Given its age and deteriorated condition, past pump failures, unnecessarily complex and outdated two stage pumping system, ongoing safety issues, and the difficulty in obtaining repair parts for 1958 vintage booster pumps, EID has made replacement of portions of the facility a high priority for the District.
The Folsom Lake Intake Improvements Project involves improvements to and the replacement of existing facilities associated with the raw water intake where water is diverted from Folsom Lake for delivery to EID’s drinking water system. A new intake consisting of stainless steel casings with temperature control withdrawal capability and new pumps will be installed along with other electrical and site modifications.
- Construct a temperature control device for EID’s intake facilities in order to preserve the cold-water pool in Folsom Lake to help enhance downstream habitat for anadromous fish species
- Replace selected existing pumps with more reliable and efficient equipment
- Provide adequate raw water supply to meet the El Dorado Hills Water Treatment Plant’s permitted capacity
- Maintain water delivery service during construction

Folsom Lake Intake Project - Update
Construction Starting June 15
EID is providing this courtesy notification for the Folsom Lake Intake Improvements Project located at the end of Planeta Way. A construction contract was awarded to Granite Construction Company (Granite) on February 24, 2020, and construction is now planned to commence on June 15, 2020.
During this first week of construction Granite will be mobilizing and clearing the site for excavation. Following this effort, Granite and their subcontractor will begin placement of temporary pumps to supplement the original A-side pumps that will then be removed to make room for the new permanent pumps, casings, and temperature control intakes. This initial pump work is scheduled for completion the first week of July.
Moving into July, Granite will continue site grading and excavation work and begin placement of the steel piles that will ultimately anchor and support the new intake structure. Heavy construction is planned through early Spring 2021 with pump commissioning and start up planned through late summer.
If you have questions regarding the project or this notice, please contact us at FLIntake@eid.org or call (530) 622-4513 and ask for a representative for the Folsom Lake Intake Improvements Project.
