D&B Project Manager: Paul Antonio, P.E.
Project Cost: $20,000,000

  • Sludge Handling Facility
  • Maintenance of Plant Operations (MOPO)
  • Reconstruction of Final Tanks
  • UV Disinfection

Project Description

Project Overview

The project includes the upgrade and replacement of the existing 2.5 mgd treatment facilities including the replacement of the trickling filters with a new biological process that can remove nitrogen and phosphorus at reduced chemical cost (sequencing batch reactors), the addition of tertiary filtration and the installation of UV disinfection. The sludge handling will be replaced with gravity thickeners, aerobic digestion and belt filter press for dewatering.
Specifically, as it relates to the Wards Island project, the Port Jervis project includes reconstruction of the final tanks to raise the drives and tank sides above the current flood elevation. This project is similar in scope to the Wards Island project in that they will also be replacing the collector system. The Port Jervis project will also be replacing influent sluice gates to the trickling filters. This project follows the current EH&S policies of the NYCDEP, all engineers will have the ten hour safety training as required by the Department. Our Quality Assurance and Quality Control is following the Departments latest Standard Operating Procedures. We are at Draft Facility Design at this moment on this project.
