Silver Lake Reservoir Complex Storage Replacement

Background Information


The Los Angeles Department of Water and Power intends to build a new Reservoir Storage Facility at the Headworks spreading grounds, a 43-acre site adjacent to the Los Angeles River and between the City of Burbank and Griffith Park.

In January 2006, the U.S. Environmental Protection Agency promulgated the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectants and Disinfection Byproducts Rule. These stringent water quality regulations resulted in the LADWP’s decision to remove some open reservoirs from service because they are open to the environment and subject to contamination. To comply with the aforementioned regulations, these reservoirs must either be covered, have their water treated prior to use, or be bypassed. Compliance with the regulations requires removal of the Silver Lake and Ivanhoe reservoirs from potable water supply service and construction of two underground reservoirs and a large-diameter pipeline located at the Headworks property, replacing the operational function of Silver Lake and Ivanhoe. The replacement storage will be below grade and consists of two water storage facilities, the Headworks East Reservoir and the Headworks West Reservoir. In order to take advantage of the renewable energy source developed by the flowing water, a four-megawatt hydroelectric plant will be built on site to generate power. After the completion of these projects, the ecosystem will be developed to establish environmental habitats and recreational facilities for community use.
