Project Description
The New York City Department of Environmental Protection (DEP) is proposing the rehabilitation and upgrade of the existing Glendale Pumping Station (PS) in Queens, NY. The existing PS is a subsurface structure located beneath the sidewalk of 71st Avenue near 75th Street and the project site includes a small portion of Block 3791, Lot 120. The proposed project would expand and rehabilitate the Glendale PS and increase its capacity from 1.2 Million Gallons per Day (MGD) to 2.4 MGD per pump to ensure that it could adequately serve the drainage area during wet weather events while providing redundancy. In addition, the proposed project is designed to provide a reliable, efficient, resilient, sustainable, and low maintenance operation in accordance with the 2014 Bureau of Wastewater Treatment (BWT) Wastewater Pumping Station Design. There has been a history of flooding in the Cooper Avenue underpass indicating that the pumping station capacity may need to be increased. In addition, the two pumps at the existing Glendale PS often operate during wet weather events leaving no redundancy. To accommodate the new electrical enclosure and space for portable emergency generator or portable emergency bypass pumping equipment, the proposed project would extend the footprint of the Glendale PS to the west where there are existing parking areas. The extended area would be surrounded by chain-link fencing to enclose the existing paved area, which will remain in its current condition. Bollards may be installed to protect the electrical enclosure from vehicles. The proposed project would maintain the existing piping layout and no new pump force mains, or stormwater drains are required. Once construction is complete, the project site would be restored to pre-construction conditions, including restoration of pavement, curbing, and sidewalks as necessary.
