Railroad Construction completed the reconstruction of the 235th Street Pump Station in the Bronx, NY for the New York City Department of Environmental Protection (NYC DEP). The original facility, which required frequent maintenance and repairs, was fully upgraded to provide reliable, modern service.

To maintain continuous operations during construction, a temporary pump station was constructed adjacent to the existing building. This system included two below-grade concrete structures, an interim pump station and diversion valve manhole that was excavated approximately 30 feet deep and supported by soldier piles. Equipped with electrical systems, piping, a standby generator and pumps with guiderail access for maintenance, the temporary station ensured uninterrupted service throughout the project. The Interim pump station wet well remains in place with a connection for the owner’s mobile pumps for future use as needed.

The above-grade structure was demolished and rebuilt on the existing foundation, while the two basement levels were fully renovated. The new 1,600-square-foot facility features upgraded electrical, HVAC, and plumbing systems, along with a cast stone veneer, new fencing and landscaping.

Additionally, approximately 1,100 feet of new 20-inch force main and 4-inch water main were installed in the surrounding roadway.

This critical infrastructure improvement enhances the system’s ability to convey sewage and stormwater to the nearby treatment plant, delivering long-term reliability and resilience for the community.
