Mayor Eric Garcetti and Councilman John Lee toured the recently completed Los Angeles Reservoir Ultraviolet Disinfection Plant in Granada Hills on Monday, May 2, which the Los Angeles Department of Water and Power said Angeles, will treat up to 650 million gallons of water every day, more than enough to twice fill the Los Angeles Memorial Coliseum.
The new plant will be the last step in a complex water treatment process. This is the second ultraviolet facility in the network, after the Dr. Pankaj Parekh ultraviolet disinfection facility in Sylmar, which treats water with ultraviolet light after it has undergone fluoridation, ozonation and filtration. City water undergoes the process before entering the Los Angeles Reservoir.
The newly completed plant will treat water that has already been stored in the Los Angeles Reservoir before it enters the city’s water distribution lines that carry water to homes and businesses in the city.
“The LA Reservoir UV Disinfection Plant Project is a critical step in ensuring that the water the Los Angeles Aqueduct provides to our region is clean and treated to the highest degree,” Lee said.
The $123 million project was financed by two state revolving funds for drinking water. The 30,000 square foot facility has 15 UV reactors, as well as complex mechanical controls and systems and uninterruptible power supply units, DWP said.
“In Los Angeles, we are taking steps to become more resilient and prepared for the drought years that are occurring with greater frequency due to climate change,” Garcetti said.
“This state-of-the-art facility will allow us to continue providing high-quality water as our state experiences a third consecutive year of drought.”
