Description: Focus on Safety, Resiliency, and Effectiveness
The consultant, Gannett Fleming (Camp Hill, Pennsylvania), initially delivered a conservative conceptual design based on a conventional submersible pumping station footprint. This arrangement was selected initially because of the small site size requirements. With feedback from DELCORA, the design team also considered a self-cleaning trench submersible arrangement, which did not require as much...

With prior pump station EPS-1, DELCORA often received odor complaints from the community. Odor sampling revealed an average hydrogen sulfide level of 13 ppm and a peak concentration of 1,044 ppm. This level is extremely high compared to other areas within the sewer system — largely due to hauled-in waste — and demanded significant odor control measures. An odor control expert was...

The PS-6 site was extremely constrained — bounded by an active 76-cm (30-in.) force main to the north, a 137-cm (54-in.) force main to the east, an active hauled-in waste facility to the south, and an electrical duct bank to the west. The latter houses two 15 kV feeders for the WRTP, medium voltage service for the existing EPS-1 pumping station, and fiber optic cabling for the entire...

In addition to the technical factors detailed thus far, a critical part of the project’s success was strategic collaboration. Pumping station operators offered consultation throughout the project as the staff responsible for the daily operations. This collaboration ensured that the project was designed to achieve maximum results in real-world scenarios.
