It’s been nearly a year since the L.A. DWP announced it was looking at temporarily draining the 800-million gallon Silver Lake Reservoir instead of digging up more than a mile of West Silver Lake Drive to install a new water pipeline. A final decision has yet to be made but DWP officials said the California Department of Public Health, which regulates public water systems, has tentatively approved the concept of constructing a double-wall pipeline within the reservoir as part of what’s called Alternative 4.
“The alternative currently being explored, namely Alternative 4, definitely requires draining the Silver Lake Reservoir for the installation of the water pipeline,” said Ruben L. Rosales with the agency’s Water Engineering and Technical Services division.
Rosales and DWP officials, however, emphasized that no final decision has been made as an environmental review is conducted. The results of the review and the latest project developments will be presented at a community meeting before this summer, Rosales said.
The idea of draining the reservoir instead of digging up West Silver Lake Drive would minimize the impact of pipeline construction. But some residents have objected to the plan, saying it would create a muddy, neighborhood eyesore for many months. Last year, the Silver Lake Neighborhood Council voted in favor of the installing the pipeline in the reservoir.
Even if the DWP decided to drain the reservoir, about 1,500 feet of West Silver Lake Drive would still have to be dug up to lay a pipeline, which would then turn into the bed of the reservoir just south of the dam that divides the Silver Lake and Ivanhoe reservoirs.
