Hanover Sewerage Authority Wastewater Treatment Plant

The Hanover Sewerage Authority was created by the Township in 1956 to provide wastewater collection and treatment service within Hanover Township. This action was taken in response to ongoing failures of septic systems and to plan and provide for future treatment needs. Planning and construction began in the mid-1950s. The plant began operation in November of 1961. At the present time, approximately 99% of the Township is sewered. The Authority also provides service to contiguous residential areas of Morris Plains, Morris Township, Parsippany-Troy Hills, and to industry in East Hanover.
