The Los Angeles Wastewater Integrated Network Systems (LAWINS) project is a significant capital improvement program initiated by the City of Los Angeles. It will integrate the city’s entire wastewater control system, conveyance system, and all four treatment plants. The DRC team is supporting the 15-year, $88.6 million Honeywell Control System Replacement Program, critical portion of LAWINS. The program is overhauling or replacing the existing control system with Honeywell’s state-of-the-art Distributed Control System (DCS). DRC is supplying instrumentation and control systems engineering and CAD services to Honeywell International, the system supplier. Work is underway on-site at the Terminal Island wastewater treatment plant in San Pedro and the Hyperion plant in El Segundo. Our team’s tasks include field validation, process and instrumentation drawings, and process engineering. The team also is developing an Input/Output (I/O) list, instrumentation database, and piping and instrumentation drawings. DRC engineers are developing control narratives based on reverse engineering extracted from existing PLC codes. This facilitates DCS’s programming. Replacing the control system will allow Los Angeles to link its four wastewater treatment plants with pumping stations located across the city. The wastewater treatment system controls 6,700 miles of sewer lines serving more than four million residential and commercial customers in Los Angeles and 29 surrounding cities.
