NJ I-Bank Project of the Week: North Hudson SA CSO Abatement Solids & Floatables Screening Authority receives $14,511,749 in Water Bank loans. Estimated savings to ratepayers of $10,493,045.

NJ I-Bank and NJDEP Helping to Improve New Jersey's Environmental Infrastructure, One Project at a Time

The North Hudson Sewerage Authority (NHSA) recently completed a CSO Abatement project that is being funded with approximately $14.5 million in loans from the NJ Water Bank, a joint low-rate funding program of the DEP and the NJ I-Bank. This project qualified for principal forgiveness totaling $5 million‬ as it improved conditions for combined sewer overflows. Including interest cost savings, total savings for this project are estimated to be $10,493,045 over the 30-year term of the loan or 72% of the total project cost. In addition, this project created an estimated 174 direct construction jobs.  

As part of the New Jersey Pollutant Discharge Elimination System (NJPDES) permit for the NHSA Adams Street Wastewater Treatment Plant, the NHSA must implement measures that will capture, remove and prevent the discharge of Solids and Floatables (SF) which cannot pass through a bar screen of 0.5 inches from all CSO points. The W1234 SF screening facility is 100 feet long x 75 feet wide and designed to remove solids and floatables 0.5 inches or greater, screened through replaceable nets at the point where the outfalls discharge into the Hudson River. The facility includes two parallel hydraulically connected, cast-in-place concrete chambers, approximately 20 feet below the water surface with flush-mounted access doors at grade, for access to replace nets and other maintenance. Construction of the facility required dredging and pile-driving within its footprint and was constructed along the alignment of the existing W1234 outfalls, extending into the river from the existing bulkhead. A platform was also constructed above the netting chambers for maintenance and to provide a public viewing deck. 

Richard F. Turner, Mayor of Weehawken, one of NHSA's major customers, applauded the NHSA for their dedication to improve the impacts from the combined sewer system. "This project brings the NHSA's NJPDES permit into compliance, reduces impacts to the environment and provides open space for residents to enjoy all with a hefty savings of 72% which will be passed on to our ratepayers." 

This project was designed by Mott MacDonald and constructed by Weeks Marina Inc.
