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

The campus conducts outreach and education about water conservation and efficiency through a variety of media, including the use of Green Screen public display monitors, annual sustainability reports, social media assets, and presentations to classes. Each of these methods are used to advertise ways to conserve water on campus and at home.


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

Recycled water is used for all irrigation on campus.


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

All toilets on campus are now at most 1.6 gpf and plans are in place to potentially convert all to at most 1.28 gpf. All urinals are waterless and student housing employs high efficiency showerheads and low-flow faucet aerators. The standard for bathroom faucets is 0.5 gpm and kitchen is 1.5 gpm or less. Additionally, about 40% of academic buildings utilize sensored faucets in bathrooms.
