Croton Water Filtration Plant Wetland Design

Bronx, NY

The Croton Water Filtration Plant is a landmark water infrastructure project in Bronx, NY built 80-feet underground and topped with a nine-acre green roof, the largest in the United States. Great Ecology served as the ecological consultants on the Grimshaw Architects team for the planning and design of a green infrastructure project to treat stormwater and groundwater onsite for irrigation use. The resulting design features multiple constructed wetland habitat cells around the perimeter of the facility that utilize native plants to naturally improve water quality. The wetland habitat designs were influenced by the natural landscapes of the Bronx and surrounding New York region. In addition, Great Ecology provided design support and plant palette recommendations for swale located around the site.
As part of this work, Great Ecology produced construction drawings, participated in value engineering and construction scheduling, designed an operations and maintenance program for the client, and interfaced extensively with the NYC client stakeholders.
Construction of the wetland cells began in 2020 with Great Ecology providing oversight and, as of January 2024, continued post-construction monitoring to ensure the wetland cells meet success criteria.
