Challenge

Sustainable urban development reaches new heights in downtown Manhattan with Battery Park. Battery Park City is a redevelopment area of 92 acres under the control of the NYC Battery Park City Authority (BPCA) of New York City.

Highlights

Combined Sewer Overflow Mitigation
All buildings receive comprehensive water reuse program rates from NYCDEP
Membrane Bioreactors
Ultraviolet and Ozone Disinfection

The Solution

“This was a very important partnership for us. They not only implemented the plant for us but they maintained it, they monitored the water and made sure it was ran efficiently.” – Miro

Summary

Natural Systems Utilities (NSU) designed, built and currently operates the wastewater reuse systems and rainwater recycling systems within six Battery Park City Buildings.

These campus utilities systems have consistently achieved greater than 50% water consumption reduction and a greater than 60% reduction in wastewater discharge (compared to similar base residential buildings in NYC). These water recycling project savings are the direct result of wastewater reuse and water conservation. Battery Park City has been developed as a model for scaling water conservation and reuse projects in urban redevelopment and campus-scale settings.

Solutions

“Building Sustainability” BPCA adopted a mission of sustainable urban development for the redevelopment of this land, including water reuse objectives, more advanced than LEED requirements. Currently, there are six existing residential water reuse systems in Battery Park City which service eight buildings: The Solaire, Tribeca Green, Millennium Tower, The Visionaire, Riverhouse, Liberty Luxe, Liberty View, and The Verdesian.

“Systems” Systems include treatment with hollow fiber micro-filtration membranes, ultraviolet light disinfection, and biological nitrogen removal to comply with New York City Department of Buildings direct water reuse standards. The total design flow for these systems is 165,000 gallons per day (gpd).”

“The Solaire” The first project in NYC to incorporate wastewater reuse was the Solaire Building, which began operation in 2003 The treated water is reused for flushing toilets in the 293-unit apartment building, cooling tower make-up, and green roof irrigation.
