The Pleasure Bay Crossing and Main Pump Station Replacement Project entails construction of two new interceptors with 30-inch and 54-inch diameters, respectively, along with a new 50-mgd main pump station (MPS) with a 36" force main extending to the wastewater treatment plant's existing headworks facility. The project will also entail diverting the wastewater treatment plant's existing supernatant flow by gravity to the new MPS, as well as demolition of the existing supernatant pump station, which will no longer be needed. The new 54-inch Pleasure Bay Interceptor (PBI), approximately 3,250-foot long, will be installed by a 10-foot maximum diameter tunnel boring machine (TBM), and will cross Pleasure Bay at a depth of approximately 90-feet ± to avoid existing soft marine soils below the Shrewsbury River. The launch shaft for the PBI TBM (within the plant's fence line) will also serve as the location of new MPS deep wet well. The reception shaft for the PBI TBM will be located at Sommers Park in the Borough of Oceanport. A 30-inch diameter interceptor will connect the existing Monmouth Bay Interceptor (MBI) from its current location near the existing MPS to the new MPS constructed as part of this project. The Contract will also include the construction of a new Electrical Building and Odor Control System to service the new 50-mgd MPS along with associated site improvements.
