Heading to Griffith Park through an equestrian tunnel under the Ventura (134) Freeway, horse riders emerge to see an unusual sight: huge yellow earth movers chomping into 15 acres of dirt between the freeway and the park.
Los Angeles Department of Water and Power is deep into building underground reservoirs that will hold 110 million gallons of water and help eliminate the city’s reliance on open-air reservoirs, including Silver Lake. When complete, the two side-by-side Headworks reservoirs will be hidden beneath an open-space recreation area along Forest Lawn Drive near the intersection with Zoo Drive.
The $230-million project was set in motion by federal regulations several years ago requiring upgraded open-air reservoirs, said Marty Adams, DWP’s director of water operations.
The laws call for reservoirs to be covered, replaced, or to have additional filtration systems built on-site, he said.
The 2007 discovery in Silver Lake Reservoir of bromate — a contaminant formed by the combination of sunlight, chlorine and the naturally-occurring mineral bromide — exacerbated the effort to enhance drinking water safety, Adams said.
