Does the institution use non-potable water (e.g., harvested rainwater or graywater) for irrigation and/or other applications?:
Yes

A brief description of the source of non-potable water and how it is used:

A small amount of harvested rain water is collected in a rain barrel for application in a rain garden designed by Alive Structures, a Brooklyn garden design firm. Water runs from a 300-gallon rain barrel that collects water off the roof through a catchment system for the downspout that pours into the rain garden. The 400-square-foot garden stretches 80 feet across behind university buildings on 120th Street and Amsterdam Avenue. About 30,000 gallons of rainwater pass through the garden annually, most of it absorbed by plant roots.
