NJ I-Bank Project of the Week: North Jersey District Water Supply Commission Infrastructure Rehab and Security Upgrades. Commission receives $17,112,622 in Water Bank loans. Estimated savings to ratepayers of $4,260,98.

The North Jersey District Water Supply Commission (Commission) recently completed drinking water improvements that are being funded with approximately $17 million in loans from the NJ Water Bank, a joint low-rate funding program of the DEP and the NJ I-Bank. Including interest cost savings, total savings for this project is estimated to be $4,26 million over the 30-year term of the loan or 25% of the total project cost. In addition, this project created an estimated 205 direct construction jobs. 

The project included the analysis of existing lagoon conditions (such as sludge levels, concentrations of metals, disinfection by-products, organic components, etc.). A detailed design was prepared for the construction of a lagoon/decant treatment system. The decanted water will continue to be discharged to the reservoir and/or be recycled back to the head of the Water Treatment Plant (WTP). 

In addition, high flow clarifiers were upgraded into the footprint of existing Basins 5 & 6 at the Commission’s WTP. The residuals will either be piped to the Commission’s current Residuals Treatment Facility or dewatered at the point of generation. 

The project also involved a security component, including the upgrade and expansion of the closed-circuit TV, installation of an access control system to control and secure all entrance and exit points to the Administration building, and security gates at the Orechio Drive entrance. Fire alarm systems were installed in all Commission-owned buildings, as well as a system to integrate, map, and monitor security sensors on the Commission’s aqueduct. 

Michael Venezia, Mayor of Bloomfield Township, one of the municipalities that contract with the Commission, applauded its commitment to provide clean, affordable drinking water. “This project provided enhanced safety measures and demonstrated shrewd money management reflected by the 25% savings of the total project costs. The services provided by the Commission are essential to public health, fire protection, and quality of life. Working in partnership with the Water Bank contributed to economic growth in the communities served by passing on the savings to ratepayers.” 

The Basin Rehab component of the project and the Clarifier upgrades were designed and constructed by Stone Hill Contracting Co. The Basin was rehabilitated by 4RO Services. The security component was designed by Arcadis.
