A brief description of the institution's water-related behavior change initiatives:

---

A brief description of the institution's water recovery and reuse initiatives:

The University installed two rainwater harvesting cisterns 2,500 gallons each using the student fee-funded Green Fund. The collected rainwater is used to irrigate annual plants in the summer and create brine mixtures in the winter. In addition to the cisterns, a non-potable water from wells is used for irrigating for a recreation facility (Piney Lake), and on-campus athletic fields (baseball and soccer)as well as the golf course. UNCG has installed sub-meters on irrigation and cooling towers to receive non-sewer credits for water that does not go into the City of Greensboro sewer system. All grass athletic fields now have automated sprinkler systems with rainwater sensors.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

UNCG has installed low flow toilets, showerheads and aerators in sink faucets to reduce the water consumption on campus. We are currently expanding the use of smart irrigation system and have trained staff to monitor the use of the system to eliminate potable water use.
