LADWP will construct the 99th Street Water Treatment Plant in South Los Angeles to provide chloramine treatment to the groundwater supply distributed by the 99th Street Wells Pumping Station Complex.

The Fairmont Sedimentation Project would improve raw water quality through a reduction in sediment in the water delivered by the First and Second Los Angeles Aqueducts to the Los Angeles Aqueduct Filtration Plant (LAAFP), where the water receives additional treatment and disinfection before entering the City’s potable water distribution system.

Replacement of the floating cover for Green Verdugo Reservoir is a key capital improvement project and is crucial to maintaining the reservoir’s water quality and supply reliability.

The San Fernando Groundwater Basin (San Fernando Basin [SFB]) provides an important source of groundwater supply for the Cities of Los Angeles, Burbank, and Glendale. The SFB acts as a large, natural underground water reservoir.

LADWP completed construction of 25 groundwater monitoring wells in various areas of the easterly portion of the San Fernando Valley. These new wells, along with a network of more than 70 existing wells, are being used to characterize the basin’s groundwater quality and develop a complex of comprehensive groundwater remediation facilities for removing contamination from the city’s major well fields in the San Fernando Basin.

A 144-inch diameter pipeline approximately 125 feet long will bring the water into the inlet channel of the UV building with a second similarly sized pipeline delivering the treated water back from the outlet channel into the water distribution network.

The Lower Franklin Reservoir No. 2 (LFR2) is a major storage facility in the LADWP’s drinking water system. This reservoir is covered by an existing floating cover that was installed in 1989 to maintain water quality by minimizing exposure to the environment. The existing floating cover is reaching the end of its service life. Under this project, the existing floating cover will be replaced and additional modifications to the reservoir’s inlet and outlet facilities will be made to improve reservoir circulation, water quality, and operations and maintenance.

Mission Wells Chloramination Station Project will a new facility that will replace the current chlorine system and will provide chloramine disinfection to the groundwater supply distributed by the Mission Wells Facility.
