The Coplay Whitehall Sewer Authority (CWSA) operates the sewage service to the entire areas of Coplay and Whitehall, as mandated by agreements with the Council and Commissioners of both municipalities in April 1963.
CWSA owns and operates a collection and conveyance sewage system that consists of manholes, mains, interceptors, pump stations, metering devices and sanitary service laterals originating at the main and terminating at the street curb line or edge of easement whichever is applicable.
It currently services over 13,500 customers with approximately 120 miles of pipe. Wastewater is conveyed to the Allentown treatment facility where harmful components are removed prior to discharging Into the Lehigh River. CWSA flows in 2006 were approximately 2,200,000 gallons/day, representing 60% of the 3,700,000 gallon treatment capacity allotted to CWSA by City of Allentown.
CWSA is overseen by a seven member Authority board, four members are appointed by Whitehall Commissioners and three members are appointed by the Coplay Council. Each member is appointed for five year terms.
