A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:
---

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

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

$20,000 from the Facilities Fee was used to replace older plumbing fixtures with fixtures that require less water. Old toilets can use 5 gallons or more per flush, newer ones use 1.6 gallons per flush. Older urinals use 3 or more gallons per flush, and newer ones use 0.8 gallons per flush. The University is also experimenting with waterless urinals which need no water. Lavatory faucets use in excess of 1 gallon per minute, newer ones will use 0.5 gallons per minute, and be automatically controlled to lessen the likelihood of faucets being left open.
