  • Knowlton Township, New Jersey


In 2012 the Town of Phillipsburg, NJ was putting into place the process by which they would expand their existing wastewater treatment facility to 4.3 mgd capacity. This facility serves approximately 28,000 residents in the Town of Phillipsburg, the Borough of Bloomsbury, and the Townships of Alpha, Greenwich, Loptacong and Pohatcong. In providing the facility’s operations, NSU was challenged with adapting the Philipsburg sewer utility facility’s existing staff into the operations plan.


  • Long Term Operations Contract


In 2013 NSU, under a long-term operations contract, and in partnership with the town of Philipsburg NJ, was named the operator for the existing 3.5 mgd facility and the expanded facility once in operation. NSU is responsible for the overall operations of all the facilities with the associated management support services, all maintenance and repairs, sludge management and disposal, and all wastewater analysis required by the Authority’s NJDEP permits. Working with the town of Philipsburg, NSU provides recommendations for capital improvements with a goal to optimize operations and reduce cost while providing safe reliable operations. In the end, NSU was able to retain existing staff and bring on additional labor from within the community.

One solution for the primary Philipsburg waste services treatment process was an Intermittent Cycle Extended Aeration System (ICEAS) modified sequencing batch reactor (SBR) system, which operates as somewhat of a hybrid SBR and extended aeration plant. One of the unique features is that the system does not require control of the influent flow and therefore does not require separate fill cycles.
