Hannah Street Pumping Station Maintenance and Protection of Traffic

The Hannah Street Pumping Station (HSPS), originally constructed in 1977, is located on Front Street south of Hannah Street in the northeast sector of Staten Island and is the largest DEP pump station in Staten Island with a conveyance capacity of 37.5 MGD. It is within the Port Richmond WPCP drainage area. 

The pumping station has numerous deficiencies, and the facility needs a comprehensive upgrade. The project is also mandated under an NYSDEC Administrative Consent Order. 

This $50M project required the rehabilitation of an existing 36-inch 2000LF± force main and the construction of 30-inch above/under ground 1500 LF± force main between HSPS and existing intercepting manhole located north of Victory Boulevard. 

The project includes the replacement of all existing mechanical equipment in the pumping station, architectural and structural modifications, mechanical upgrades, HVAC and plumbing, and the construction of an interim pump station to serve during the improvements. A new ConED building will be constructed to feed the new electrical building and the generator that were raised above the 500-year Critical Action Floodplain.  Site layout, grading, and drainage improvements were addressed to meet storm water requirements. The existing force main was rehabilitated using CIPP.   

IEI assisted NYCDEP in the stormwater/drainage design within the site, grading, rehabilitation of the 2000 LF 36-inch Force Main located within the NYCDOT Right of Way. IEI provided QAQC and led the design for the maintenance and protection of traffic (MPT) and staging for the construction of the 36-inch and 30-inch force main located within the NYCDOT ROW.
