Sanitary Sewer Utility

The Sewer Utility operates and maintains a 16 million gallon per day (MGD) advanced wastewater treatment plant, which currently has an average daily flow of 9 MGD. The Sewer Utility also operates and maintains approximately 370 miles of sewers and 28 pump stations which make up the Collection System. The Wastewater Treatment Plant and Collection System operate under permits issued by the New Jersey Department of Environmental Protection (NJDEP).

Sewer Plant

The highly treated wastewater, which meets all NJDEP Permit Requirement flows into the Rockaway River where it meets the Whippany River. The bio-solids (sludge) produced by the advanced treatment process are dewatered and sent to an out of state landfill.

FOG Facility

Septic tank waste, sewage sludge and gray water are accepted from the area for treatment at the Plant. A Fats, Oils and Grease (FOG) Facility operated by a private firm through a lease agreement with the Township also operates at the Plant and accepts food type FOG for treatment.

Operation & Maintenance

The Sewer Utility operates and maintains all sanitary sewers in the Township from the cleanout in front of homes and businesses to the Treatment Plant.

Wastewater Treatment Plant

The Parsippany-Troy Hills Wastewater Treatment Plant through agreement accepts and treats wastewater from Mountain Lakes, East Hanover, Montville and a portion of Denville.

The Sewer Utility develops plans and programs for the extension and improvement of public sewer services in the Township and at the Treatment Plant. The operation and maintenance of a Wastewater System is capital and maintenance intensive undertaking. Because of the nature of the material being handled and the ever changing NJDEP Permit Requirements the Sewer Utility must always be vigilant in its efforts to provide the level of service required by the NJDEP and demanded by the Citizens.
