MIDDLESEX BOROUGH REHABILITATION OF SANITARY SEWERS

Middlesex Borough recently completed clean water improvements that are being financed with approximately $1 million in loans from the NJ Water Bank, a low-rate funding program jointly administered by the DEP and the NJ I-Bank. Including interest cost savings, total savings for this project is estimated to be $226,675 over the 30-year term of the loan or 23% of the total project costs. In addition, this project created an estimated 12 direct construction jobs. 

The Borough replaced aging equipment to rehabilitate its Greenbrook Road and Louis Avenue pump stations. The project addressed issues identified by an Infiltration/Inflow (I&I) Study conducted by the Borough which located where water was leaking into the conveyance pipes. These pump stations have submersible pumps, or wet pumps, and dry wells which have the following advantages: sewage flows into a collector and then passes through a dividing chamber with a self-cleaning separator of coarse solids before entering the retention module. Pumps and pipework are traditionally installed in a dry well which also houses electrical and control equipment. This configuration enables safe entry and operation of the pumps and pipework. Improvements included the rehabilitation of the dry wells, the replacement of submersible pumps and the installation of gate valves, check valves, and knife valves.

Leonard Vidal, Superintendent Certified Professional Waste Management of Middlesex Borough listed the benefits of the project. "We improved the efficiency of our sanitary sewer system which will be cost effective and benefit the environment. Borrowing from the NJ Water Bank helped us to save money on the project and the improved system will save us money in the future. Our ratepayers and the environment will benefit greatly, for very little cost."
