The City of Burlington recently completed drinking water improvements that are being funded with approximately $919,021 in loans from the NJ Water Bank, a joint low-rate funding program of the NJDEP and the NJ I-Bank. Because the project serves a population of 10,000 or less, it qualified for a Water Bank NANO loan which includes principal forgiveness totaling $485,474. Including interest cost savings, total savings for this project is estimated to be $634,083 over the 20-year term of the loan or 69% of the total project cost. In addition, this project created an estimated 11 direct construction jobs. 

The project entailed the replacement of the dual filter media at each of the four filters at the City’s water treatment plant to address degradation of the Wheeler Bottom Underdrain System. 

Existing media was vacuumed out of the filters with Vactor sewer cleaning trucks and new wheeler filter bottoms were inserted into the bottom of the filter and filled with a layer of ceramic balls. Additional layers of sand and anthracite media were added. The filter headers were reinstalled, and the piping under the filter bay was modified. 

Barry W. Conaway, Mayor of Burlington City, commended the project. “This was a critical project as it enhanced drinking water for the community and brought us into compliance with NJ DEP regulations. By financing the project through the NJ Water Bank, we were able to achieve these results while saving our ratepayers almost 70% of the total project costs.”

This project was designed by Environmental Resolutions, Inc., and constructed by Level-1 Construction.
