Optional Fields

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

---

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

Numerous buildings on campus have storm water cisterns that allow rain water to be treated and used for laundry, flushing toilets, and irrigation.

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

Renovations that increase utility efficiency may be made using funding from the Green Fee Revolving Fund after approval from both the Student Environmental Initiatives Committee (SEIC) and the Facilities Services Oversight Committee. These renovations must have a return on investment of less than five years. Facilities Services performs regular assessments to identify buildings which are eligible for this funding.

Additionally, several smaller projects are currently in progress to increase water efficiency on campus. For example, all older water fountains are being replaced with energy-efficient water bottle refill stations.
