Warren Township Sewerage Authority (WTSA) - Stage V Sewage Treatment Plant

The WTSA's primary responsibility is to plan for, construct, operate and maintain wastewater facilities within the Township. The Authority’s sewerage system is divided into five sewer service areas, denoted by the Stage I and II service area, the Stage IV service area, the Stage V service area, the Middlebrook service area, and the Berkeley Heights service area. These areas are each served by a separate sewerage treatment plant. Sewage from the Middlebrook area discharges through the Township of Bridgewater (“Bridgewater”) and is eventually treated at the sewerage treatment plant operated by the Somerset Raritan Valley Sewerage Authority (“SRVSA”). Sewage from the Berkeley Heights area discharges through the sewerage collection system and is eventually treated at the sewerage treatment plant operated by Berkeley Heights.
