Croton Water Filtration Plant Awarded MENY 2016 Project of the Year
(NEW YORK, NY – October 7, 2016) – The Municipal Engineers of the City of New York (MENY) has selected the Croton Water Filtration Plant as the 2016 Project of the Year.
A formal presentation of the award was made at MENY’s Annual Dinner Dance held on November 18, 2016 in Queens.
The Croton water supply plays a fundamental part in New York City’s water supply system, providing up to 30% of NYC’s drinking water. In order to comply with more stringent water quality regulations, the City entered into a Consent Decree with USEPA and NYSDOH. The City obtained State approval in 2004 for construction of the facility. The AECOM/Hazen and Sawyer joint venture prepared conceptual designs, performed environmental impacts studies, prepared preliminary and final designs, and provided design services during construction and start-up operational services for this landmark plant, located under the Mosholu Golf Course, within Van Cortlandt Park.
Built entirely underground and requiring deep rock excavation and tunneling for the necessary conveyance tunnels, the four-story, 290-mgd plant will provide a safe and reliable water source for generations to come. A high level of innovation was demonstrated by this project, including: use of stacked dissolved air filtration/flotation (DAF) tanks (the largest in the world), followed by ultraviolet light (UV) disinfection (one of the largest in the world); state-of-the-art digital automation architecture and systems; and utilization of extensive Computational Fluid Dynamics (CFD) and physical modeling throughout the design. The plant is designed as two 50 percent capacity process trains, capable of independent operation, to provide added operational flexibility and redundancy. The plant ensures a safe and reliable Croton water source for the future, as the City shuts down other water supply sources for maintenance and to make necessary repairs.
The design of the massive facility features an impressive array of sustainability measures that minimize the facility’s impact on the environment and improve the quality of life in the surrounding community. The nine-acre golf course that covers the plant is said to be the country’s largest green roof. In total, the green roof and surrounding wetlands utilize natural processes to control and filter 40 percent of the site’s stormwater.
