Southwest Water Treatment Plant Filter Rehabilitation Phases I & II

Manchac Consulting Group, Inc. was retained by the City of Lake Charles, LA to provide engineering design, construction management, and resident inspection services for rehabilitation of the existing filtration system at the Southwest WTP including, but not limited to, replacement of the filtering media and associated internal components, replacement of all pneumatic valves/actuators, installation of new backwash pumps with variable frequency drives, and upgrades to/replacement of the filtration system control scheme. The objective was to remediate water color concerns by improving the system’s ability to treat at varying service rates and backwash efficiently and effectively. Thus, extending the useful treatment life of the filtering media and reducing media attrition to mitigate water color concerns.
