LADWP – Aqueduct Plant UV Disinfection Facility, and LAR UV Disinfection Facility

ProjectLine provided electrical, instrumentation and control systems design for the new 600 million gallons/day UV Disinfection Facility for LADWP’s Los Angeles Aqueduct Water Treatment Plant. ProjectLine was subconsultant to ARCADIS (formerly Malcolm Pirnie) for the project. The facility has 14 UV reactors, each with a maximum flow of 60 MGD, controlled by an Allen Bradley PLC provided by the reactor manufacturer. A redundant Controlnet network links each local control panel to a master PLC/ HMI in the facility control room. The master PLC communicates with both the Plant Control Room SCADA, and the City’s LAWSDAC. ProjectLine also provided point to point wiring diagrams, and cable and conduit schedules in accordance with LADWP design standards. LADWP was responsible for installing the equipment. Projectline subsequently provided similar services for a second UV disinfection facility treating water from the LA Reservoir prior to entering the City water distribution system. ProjectLine was subconsultant to the MPAC Consulting team for this project, which is a joint venture between Arcadis and Carollo Engineers.
