Mole Constructors successfully completed the excavation of 1,600 linear feet of tunnel for the Valley Belt Gravity Sewer Project. This project involved jacking two 800-foot runs of 42-inch diameter, 8-foot-long Reinforced Concrete Pipe (RCP) Class V jacking pipes, using a 42-inch Microtunnel Boring Machine (MTBM) for the excavation.
The purpose of the Valley Belt Gravity Sewer Project was to construct a new gravity sewer to bypass a section of the Brooklyn Heights Branch of the CVI. This section contained an aging pump station and force main located on Valley Belt Road, beneath the First Energy high tower transmission lines. By constructing the bypass, the District planned to decommission the outdated pump station and force main. The District estimated that replacing the pump station and force main with a gravity sewer would be more cost-effective in the long term, reducing maintenance costs and eliminating the risk of service disruptions due to pump station failure.
