PS&S was tasked with providing a long-term solution for handling non-tidal storm events along Route 35 on the Barrier Island from Bay Head to Seaside Park.
The challenge for the project team was to design a stormwater pumping system to provide a drainage solution for the entire Route 35 corridor from Milepost 0 to 4 and 9 to 12.5; handle a 25-year storm event; create a robust, watertight storm pipe system; controll all aspects of the system within the street rights-of-way; allow tidal flooding to occur without affecting electrical components of the pump stations; and provide an aesthetic design for the residents.
THE PS&S SOLUTION
PS&S designed and administered, through construction, nine stormwater pump stations, which included conceptual design concepts as well as all mechanical, electrical, and architectural design coordination. Stations were able to handle between 14,000 gpm and 36,000 gpm. All electrical components were designed to be positioned two feet above ABFE via innovative residential-style gazebos. Facilities were designed for a 25-year storm event captured from the Route 35 corridor and pumped to the bay. Design facets consisted of upstream oil-water separators with bar screens, and MTDs (mechanical treatment devices). PS&S coordinated and reviewed all shop drawings and RFIs through construction, while also being responsible for overseeing station start-ups. Project funding was via FEMA grant monies as a result of Superstorm Sandy relief efforts.
