Going Down: Silver Lake Reservoir will soon be left high and dry

Going Down: Silver Lake Reservoir being drained

SILVER LAKE — A giant bathtub ring has formed around the concrete banks of the Silver Lake and Ivanhoe reservoirs as they are being temporarily drained to build a new water pipeline.

Since August, about 100 million gallons of water have been drained from the Silver Lake Reservoir, the larger of the two bodies of water, according to Albert Rodriguez, a spokesman for the L.A. Department of Water & Power. The water has been “filtered, treated and served,” said Rodriguez. That leaves about 250 million gallons of water to go.

Enough water will have been drained by the end of the year to start construction of a bypass pipeline on the bed of the reservoir, Rodriguez said.  The reservoir will be refilled once the 66-inch wide pipeline, which is also being installed under a section of West Silver Lake Drive, is completed next year. Meanwhile, the Ivanhoe reservoir, the one covered with those black shade balls, is also being drained.  Once it’s taken out of service, the shade balls will be removed and recycled, he said.

Work on installing the pipeline under West Silver Lake Drive began earlier this year. The next phase will extend the same pipeline for about 3,000 feet across the bed of the reservoir and also involve the construction of a new water regulation station.

The pipeline project is, in general, on schedule but there have been some delays involving work under West Silver Lake Drive, a section of which has been temporarily turned into a one-way, northbound street during the construction. That construction was supposed to end this fall but now it looks like it won’t get finished until January of next year.

“The last section of in-street construction for this project, which is the pipe connection on Armstrong Ave at West Silver Lake Drive, will begin in November 2015 and last approximately 3 months,” Rodriguez said. “This portion of the work was postponed due to operational timing requirements for this complex connection work.”

The new bypass pipeline is part of a larger project that will see the Silver Lake and Ivanhoe reservoirs permanently removed from the city’s potable water system and replaced by a new reservoir buried north of Griffith Park. The project will allow the LADWP to meet  more stringent federal water quality guidelines and keep the Silver Lake and Ivanhoe reservoirs as open bodies of water.
