The North Street Pump Station is a 6 MGD facility that serves the Port Jervis Wastewater Treatment Plant located on the border of New York and Pennsylvania in Orange County, New York. Recent improvements to the pump facility, which includes manual bar screens, a comminutor, a flight and chain type grit removal system, and grit washing, had included the replacement of pumps. However, the supporting equipment was not included as part of the initial upgrades. Due to health and safety concerns with regard to the condition of the equipment and flooding conditions at the pump station during storm events and high flows, Savin Engineers was retained by the New York City Department of Environmental Protection to perform a fast-track design of the screening and grit removal equipment.

The design called for the removal of the existing flight and chain elevator type grit removal equipment and replacement with grit auger screws with grit pumping to a new grit washer/classifier, and replacement of the comminutor and manual bar racks with relocated automated screens and screening washer. To accommodate the new equipment and maintain motors above the existing flood level, a new intermediate floor was constructed within the existing pump station. The work was completed while the pump station remained in operation.
