NORTH HUDSON SA ADAMS STREET WWTP PHASE 2 IMPROVEMENTS

he North Hudson Sewerage Authority (NHSA) recently completed waste-water treatment plant improvements that are being funded with approximately $1.4 million in loans from the NJ Water Bank, a joint low-rate funding program of the DEP and the NJ I-Bank. Total savings for this project are estimated to be $664,817 over the 30-year term of the loan or 47% of the total project cost. In addition, this project created an estimated 17 direct construction jobs. 

The events of Superstorm Sandy demonstrated the need for upgrades at NHSA's wastewater treatment plants and within the collection system. This project includes various improvements to increase the resiliency of NHSA facilities for future emergency events. 

The secondary/tertiary treatment process at the Adams Street WWTP consists of a dissolved air floatation and combined sand filter process (PURAC) followed by ultraviolet disinfection. The PURAC Flo-filter process system was installed over 20 years ago. It is a critical secondary and tertiary treatment process which is required to keep the plant in compliance with its NJPDES permit. The system is nearing the end of its useful life and beginning to show signs of failure. Additionally, the system needs a new and more flexible SCADA computerized control system. Restoration work will include new underdrains and sand media for each PURAC cell, replacement of instruments and valves, replacement  of nozzles for introducing dissolved air, new chain and flight mechanisms for float removal and all associated work related to the replacement of pumps, motors, valves, piping, etc. 

According to Jennifer Gonzalez, Director   of Environmental Services for the City of Hoboken, "This project benefits Hoboken and many surrounding communities in Hudson County in several different ways. It is an excellent example of the NHSA's dedication to provide efficient wastewater treatment. The project elevates the plant's compliance, provides resilience in the case of future storms, alleviates street flooding during wet weather events, and with NJ Water Bank financing, saves ratepayers half of the total project costs.
