Project Map
Project Background
LADWP is in the process of converting its water supply to chloramine disinfection to ensure compliance with new and more stringent water quality standards modified under the Federal Disinfectants/Disinfection Byproduct (D/DBP) Rule which were promulgated in January 2006. Conversion to chloramine disinfection will be achieved with a controlled feed of aqua ammonia with chlorine solution into the water supply.
Although the Water System is serving some areas being served exclusively with chloraminated supplies from the Metropolitan Water District (MWD), chloramination and ammoniation facilities must be developed to convert the entire water distribution system to chloramine disinfection to ensure compliance with the D/DBP Rule.
The development of the Van Norman Chloramination Stations 1 & 2 (VNCS 1&2) will allow a major portion of the City’s water supply to be converted to chloramine disinfection. In addition to improved water quality, conversion to chloramines will improve the reliability of the water supply by allowing the unrestricted use of chloraminated MWD supplies.
Scope of Project
VNCS 1 & 2 included the construction of two single story buildings, averaging 7,200 sq feet each, to be used for water treatment. Control systems within the buildings will permit aqua ammonia solution will be fed with chlorine solution into the water supply to produce a chloramine residual of 3 parts per million (ppm). Both treatment facilities are located within the LADWP owned Van Norman Complex, which includes approximately 1,260 acres and includes many existing major water and power facilities.
Status
Construction of both chloramination stations was completed in February 2012.
