Summary
In partnership with Natural Systems Utilities, The New School implemented advanced water conservation measures and a state-of-the-art on-site water treatment and reclamation system at The New University Center on 5th Avenue. Designed to slash water consumption by 74% and reduce combined sewer discharge by an impressive 89%, this system captures and treats all wastewater—including “blackwater” from toilets, sinks, showers, and laundry—directly within the building.
In addition, stormwater collected via vegetated green roofs is incorporated into the reclaimed water supply, further enhancing sustainability efforts. At 40,000 gallons per day, The University Center boasts one of the largest in-building water recycling systems in New York City, setting a new standard for urban water efficiency and environmental stewardship.
Challenge
Across the globe, many communities are facing—or have already surpassed—the limits of their sustainable water supplies. In numerous regions, demand outpaces the natural availability of water, while traditional practices of diversion, consumption, and disposal continue to deplete vital resources and harm ecosystems.
To confront these urgent challenges, The New School adopted a “water fit for purpose” strategy—carefully evaluating every water source and identifying every opportunity to reduce consumption. This forward-thinking approach sets the foundation for smarter, more resilient water management that aligns use with need, minimizes waste, and protects precious resources for the future.
Solution
The University Center uses an advanced water recycling system that cleans and treats wastewater right on-site, so it can be safely reused. The process starts with a special filter system called a membrane bioreactor (MBR), which removes tiny particles and impurities from the water.
Next, the water goes through two steps to kill any remaining germs: first, it’s treated with ozone, which also helps remove any color or odors; then, it’s exposed to ultraviolet (UV) light for extra cleaning. This treatment makes sure the water meets very strict safety standards set by New York City—standards similar to the toughest ones used across the country.
The clean water is stored in a tank where it’s constantly circulated through the ozone and UV systems to keep it fresh and safe. Any leftover dirty water and sludge are sent to the city sewer system for proper handling.
To make sure water is always available, the system has automatic valves that add regular drinking water if needed—so even if the recycling system is being repaired, water service won’t be interrupted.
Everything is controlled by a computer that runs the system smoothly and alerts the NSU team if there’s a problem, ensuring safe, reliable water recycling around the clock.
Highlights
-
Among the first buildings approved to use recycled water for laundry
-
Compact wastewater treatment plant design helps preserve valuable open space
-
Design-build-operate approach reduces risk for the building owner by streamlining project delivery and management
Achievements
The University Center stands as one of the pioneering buildings approved to use treated recycled water for laundry operations. Beyond laundry, this reclaimed water is also used for toilet flushing, irrigating the green roof, topping up the cooling tower, and maintaining sidewalks.
Through a comprehensive water management strategy—including water-saving fixtures and an advanced on-site treatment and recycling system—the University Center earned all available Water Efficiency points under LEED certification. Additionally, it secured multiple credits in Sustainable Sites and Innovation in Design, setting a new benchmark for sustainable building practices.
