Summary
Natural Systems Utilities (NSU) designed, built, and currently operates the wastewater and rainwater recycling systems within six Battery Park City Buildings. These systems have consistently achieved greater than 50% water consumption reduction and a greater than 60% reduction in wastewater discharge (compared to similar residential buildings in NYC). These water and wastewater 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.
Challenge
Battery Park City (New York) is a 92-acre redevelopment under the control of the Battery Park City Authority (BPCA) of New York City. They wanted to reach new heights in designing this sustainable urban development and needed innovative water system solutions to meet their sustainability goals. BPCA adopted a mission of sustainable urban development for the redevelopment of this land, including water reuse objectives, more advanced than LEED requirements. Working together we needed to find creative solutions, update regulations and fulfill our clients’ groundbreaking environmental impact goals.
Achievements
These systems have consistently achieved greater than 55% water consumption reduction and a greater than 65% reduction in wastewater discharge (compared to similar base residential buildings in NYC). These water and wastewater 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.
Achievements
- Combined Sewer Overflow Mitigation
- All buildings receive comprehensive water reuse program rates from NYCDEP
- Membrane Bioreactors
- Ultraviolet and Ozone Disinfection
Solution
NSU and BPCA worked together to develop six 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 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. 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.
