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).
In accordance with New Jersey Department of Environmental Protection Administrative Order 2021-2025, the Township of Parsippany-Troy Hills Sewer Utility will hold a public hearing for the purpose of receiving oral and/or written comments on its Title V Air Permit Renewal Application submitted to the New Jersey Department of Environmental Protection on October 15, 2018. The hearing will be held on September 22, 2022, from 6:00 pm to 7:00 p.m. at the Township Municipal Building, Council Chamber located at 1001 Parsippany Boulevard, Parsippany, NJ.
7-22-2022 Pump Station #4 Redirection Project
The Township of Parsippany-Troy Hills owns and operates the sanitary sewer collection system and wastewater treatment plant. The Lake Hiawatha area of the Township is served by Pump Station No. 4.
Pump Station No. 4 is the largest wastewater pumping station in the Township’s Sewer Service Area, and conveys wastewater to the Township’s Wastewater Treatment Plant via an 8,900 linear foot, 24-inch diameter, PCCP force main. This Pump Station and its force main, constructed around 1963, are at the end of their useful life. The Force Main has in the past required emergency repairs. The Pumps Station is approaching its flow capacity and needs rehabilitation and upgrades. Also, should a major failure of the Pump Station or Force Main occur, it will be necessary to convey the wastewater from the north side of Routes 46 and 80 to the south side. This will be challenging during emergency situations.
After an Engineering Study, redirecting the flow from this area via a gravity sewer to the existing 72-inch Troy Meadow Interceptor was identified as the preferred and most feasible alternative. Construction of this Project will commence soon and should be completed by the beginning of next year. This redirection will be accomplished by directional drilling a 60-inch casing pipe and then the insertion of a 48-inch carrier pipe, under Routes 46, 80 and 280. Upon completion of this proposed gravity sewer connection, the Pump Station will be taken out of service providing considerable energy savings and the reliability of providing wastewater conveyance will be greatly enhanced.
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.
Septic tank waste, sewage sludge and gray water are accepted from the area for treatment at the Plant.
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.
