Project Scope

The project consisted of an upgrade to the Avenue “V” Pumping Station and two new force mains. Current pumping capacity is 30 mgd. The project was designed to upgrade the station with increased capacity to 80 mgd and allow unnamed operation, improve the appearance of the pumping station, and also to solve sewer capacity problems and eliminate CSO overflows into Coney Island Creek. The existing superstructure was constructed in 1917, with additions made in 1960 and 1973. 

The facility’s exterior appearance has been improved by demolishing and rebuilding a large portion of the structure, including the additions that were added to the structure after 1917. The original Beaux Arts architectural style was restored as part of this project. Presently, the pumping station capacity was inadequate to pump the entire wet flow to the Owl’s Head WWTP, and therefore, overflows occur into Coney Island Creek, causing hypoxia and environmental degradation. In addition, sewer backups occur due to the high wet well elevation. Solutions to these problems included lowering the wet well, additional pumping equipment and new force mains to diver pumped flow from the Coney Island Creek to the more open waters of outer New York Harbor through two separate CSO systems. After the upgrading, during dry weather, all sewage has been pumped to the Owl’s Head WWTP. The new station capacity will be 80 mgd. In addition, improvements have been made to the existing interceptor system, including lining a portion of the existing box sewer SE-133 and performing modifications to regulator OH 1. Landscape protection and restoration were performed along the Belt Parkway portion of the route. The pumping station and force main contracts included: PS- 17G, Structures and Equipment: PS-79H, HVAC; PS-79P, Plumbing; PS-79E, Electrical; and PS-79F, Force Main.
