The Passaic Valley Sewerage Commission recently rehabilitated 12 final clarifiers and installed a new scum removal system at its Newark Waste Treatment Plant using $22 million in loans from the NJEIFP program. This project was initiated to address removal of surface dirt, increase the lifespan of steel structures, enhance operational performance, and reduce maintenance. The executive director of PVSC noted that the organization has saved tens of millions of dollars in financing costs through loans from NJEIT since 1996. The clarifiers help settle solids prior to discharge and return activated sludge to treatment.

NJEIT Project of the Week: Passaic Valley Sewerage Commission (PVSC) Final Clarifiers
Community Receives $22,162,500 million in NJEIFP loans: Estimated Savings to rate payers over $10 million.
The Passaic Valley Sewerage Commission recently rehabilitated 12 final clarifiers and installed a new scum removal system at its
Newark Waste Treatment Plant. The project is being funded with $22 million in loans from the NJEIFP, a joint funding program of
the DEP and the NJEIT. This project was initiated to address the removal of surface-level dirt, increase the life span of the steel
structures, enhance operational performance, and reduce maintenance for the twelve final clarifier tanks. PVSC also qualified for
an additional $2.5 million in principal forgiveness funds.
PVSC Executive Director Gregory Tramontozzi recently noted: “PVSC greatly appreciates the long-term partnership we have
developed with the NJEIT and its low-interest Clean Water loan program. PVSC is proud to be one of NJEIT’s largest borrowers.
NJEIT has saved PVSC and its rate payers tens of millions of dollars in financing costs since our initial loan in 1996.”
The clarifiers provide inert conditions to promote the settling of biological solids prior to disinfection and discharge of final
effluent. They also provide for the collection and return of activated sludge to the oxygenation tanks for biological treatment as
well as the collection and removal of surface dirt and film. This project was designed by T&M Associates and built by Stone Hill
Contracting Co., Inc.
