Background
The Green Verdugo Reservoir is an LADWP drinking water storage facility located in the Sunland area of the San Fernando Valley. The reservoir is formed by an earth fill dam and was first placed in service on September 28, 1953.
The previous floating cover at the Green Verdugo Reservoir was installed in 1989. As a result of damage sustained in the September 2017 La Tuna Canyon fire, the 31,000 million gallon reservoir was taken out of service until the replacement of the floating cover and related reservoir improvements were completed. The reservoir was returned to service in April 2024.
Two water quality regulations mandated by the United States Environmental Protection Agency necessitate these critical infrastructure improvements and are described as follows:
- Stage 2 Disinfectants and Disinfection Byproducts Rule (S2DDBPR)
Addressing risks from microbial pathogens, disinfectants, and/or disinfection byproducts, S2DDBPR requires compliance with new disinfection byproduct standards. - The Long Term 2 Enhanced Surface Water Treatment Rule addresses covering existing reservoirs and/or providing increased protection from microbial pathogens.
