Coney Island Wastewater Treatment Plant

Coney Island Wastewater Treatment Plant


The Coney Island Wastewater Treatment Plant is located in Sheepshead Bay Brooklyn, New York. Its borders are located at Avenue Y to the North, Voorhies Avenue to the South, Coyle Street to the West and Shell Bank Creek to the East. The plant has been in operation since 1952. The plant site is approximately 30 acres, of which 8 acres are dedicated to recreational facilities for the adjacent community.

To comply with the Clean Water Act, beginning in 1983 until completion in 1993 the plant was upgraded from a modified aeration plant to a full secondary plant. Because the site is limited, the upgrading was performed in a series of 12 construction phases and construction contracts at a cost of over $600 million. Today it provides treatment for 110 mgd of wastewater at average conditions and has a maximum capacity of 220 mgd of wastewater for the 684,569 New Yorkers it serves.


Project is scheduled to be completed in December 2011.


Cost of the Coney Island Wastwater Treatment Plant project is $48 million.

Community Issues

Because of the close proximity to the neighborhood, odor control is an on-going issue at the plant. To alleviate any odor issues, the plant is equipped with an extensive odor control system and the primary and aeration tanks are covered.
