Newtown Creek Relief Sewer


Brooklyn/Queens, New York<br style='line-height:2px'>New York City Department of Environmental Protection

The New York City Department of Environmental Protection (NYCDEP) is working with the New York State Department of Environmental Conservation to plan, design, construct, operate, and evaluate combined sewer overflow (CSO) abatement projects in all 18 of New York City’s water bodies. 

HAKS, as a member of the project team, is providing surveying, civil/structural design and construction support services for a $200 million CSO project at Newtown Creek for the NYCDEP. The Newtown Creek facility plan will construct a relief sewer that can aid in reducing CSO discharges in an effort to eliminate odors, greatly reduce floatables, and improve dissolved oxygen concentrations to meet existing water quality standards. 

Project elements include design of a 72-inch-diameter relief sewer to the East River at the Bowery Bay Drainage Area near Dutch Kills; floatable controls for three Newtown Creek drainage area outfalls; and bending weirs for two regular chambers in the Newtown Creek drainage area. Building information modeling is being utilized to produce three-dimensional models of all designed facilities. 

The project began in September 2011 and is expected to take approximately 8 years to complete.
