New York Completes Wastewater Plant Reconstruction

The New York Department of Environment Protection, US, has completed a $25.6m project to reconstruct the odour control system of the Coney Island Wastewater Treatment Plant and replace its fire alarm system.

The reconstruction included the replacement of 11 carbon absorbers and two wet scrubbers, a new supervisory control and data acquisition system, and a new gas detection system for the primary settling tanks.

The project was launched in 2004 to prevent hydrogen sulphide from escaping into the surrounding area.

The department replaced the plant’s obsolete fire alarm system at a cost of $11.8m. The new system will improve safety for workers, safety responders and the local community.

The Coney Island Wastewater Treatment Plant is designed to treat 110 million gallons of wastewater a day during average conditions and can increase to 220 million gallons a day when required.
