Optional Fields

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

Behavior change initiatives are focused on reduction of hot water usage. For managed lands, the focus is on using river water or rain cistern water whenever possible.

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

Ecodorm harvests rainwater from its roof and stores it in a 10,000 gallon underground railroad car. This water is used for toilets in the dorm as well as watering the garden in front of the dorm. Irrigation used in the College research and plant demonstration greenhouses is from a rain cistern.

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

Every dorm on campus has been retrofitted with more efficient water heads.
