System Wide Chloramination Trailer Improvement
Document Type
NOE - Notice of Exemption
Document Description
The System-Wide Chloramination Trailer Improvement Project proposes the installation of eleven chloramination containers or trailers at water tanks located in multiple locations within the City of Los Angeles. Each tank will have either a container or trailer on site. Each container and trailer will contain the necessary equipment to perform automatic chloramine boosting to maintain a consistent residual within a tank. The Containers and Trailers will be purchased pre-equipped with several components: storage and injection pumps for sodium hypochlorite and liquid ammonium sulfate, online analyzers, and tank mixer. Each Container and Trailer will be connected to its designated distribution tank where a residual control system will automatically inject chlorine and/or ammonia into the tank through a mixer when the residual falls below a set level. The proposed work will require the installation of piping and conduit to connect the containers and trailers, and two locations will require minor grading and concrete pads.
