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:

Both the new Student Rec Center and the Clinical & Translational Research building (both LEED Gold) have large tanks for storage of rainwater and condensate from the air-conditioning system. This water is used for irrigation of the surrounding landscaping.


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):

Low-flow shower heads: 616 standard shower heads were replaced with efficient 2.0 gallon/minute heads. Reduces water use by an average of 11%, saving over $34,000/year.
Low-flow faucet aerators: Installed 20,426 pressure independent aerators. Reduces water consumption at sinks by an average of 58% for an annual savings of over $159,000.
