Several elected leaders recently joined the Los Angeles Department of Water and Power (LADWP) in celebrating the completion of their second UV disinfection facility.
The Los Angeles Reservoir Ultraviolet Disinfection Plant (LARUVDP) is located in the San Fernando Valley and is the last stop in LADWP’s complex network of water treatment processes at the Los Angeles Aqueduct Filtration Plant.
This second UV facility supplements the LADWP’s Dr. Pankaj Parekh Ultraviolet Disinfection Facility which treats water with ultraviolet light that has already undergone several treatments– including Fluoridation, Ozonation, and filtration– before it enters the LA Reservoir. The new UV plant treats the water with ultraviolet light once again, at the outlet of the Los Angeles Reservoir, before it enters LA’s water distribution pipes that transport water to LA’s homes and businesses. The LARUVDP can treat up to 650 million gallons of water per day.
The approximately $123 million project was funded by two Safe Drinking Water State Revolving Fund awards. Based on the bond rate available at the time of project inception the estimated total interest savings for LADWP ratepayers, is close to $16.5 million.
The LARUVDP consists of a 30,000 square-foot structure that houses 15 UV reactors, intricate controls and mechanical systems, and uninterruptable power supply units. The project also features over 50 large valves with varying sizes between 32 to 144 inches, a 3-leg flow control station, five seismic resiliency vaults, and one 2,500-kilowatt diesel generator.
