The Croton Water Filtration Plant exemplifies the contemporary trend of multi-use infrastructure with an emphasis on public space and sustainability programmed into a large-scale and complex program. This endeavor demonstrates environmental stewardship and best practice for storm water management on an urban scale. The project synthesizes disparate programs to produce a
high-performance multipurpose solution improving upon the urban environment. With the support of the city agencies, the design team has rigorously persisted to retain the integrity of an integrated approach to the buildings and surrounding natural landscape while striving to embed sustainable practices into a living and thriving environment. Inherent to this approach is the belief that sustainable design excellence can be realized as an integral work of urban infrastructure.
Functionally, the design provides habitat, park restoration, visual enhancement, facilities and, above all, site security for a multi- billion dollar public works facility. Located in an environmentally sensitive site of historic Van Cortland Park, the project includes riparian woodlands and wet meadows that are to be protected. The landscape program incorporates a sustainable 9-acre green roof within an 11-acre driving range, which is located over the subterranean water filtration plant. It is also driven by security requirements while creating a natural terrain at the driving range. The result is a landscape earthwork where there is nearly two miles of site walls that constitutes a moat surrounding the site and plant. This moat is also the wetland treatment cells of the stormwater treatment system.
Principal goals for the project were:
- To minimize the discharge of site water into New York City’s combined sewer through storm water and ground water detention on site beyond that of required city
- To minimize the use of potable water on site through the reuse of retained storm and ground
- To create native ecological habitat on
