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:

Where low flow aerators were installed, there are small cards drawing attention to the fact that the aerators were installed to reduce water consumption.

One resident hall and one house owned by the College have water consumption metered and is accessible to occupants.


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

We capture rainwater from a parking lot then hold it in a rain garden while it is being filtered, which eventually waters trees and other 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):

The majority of sink faucets have been converted to use 1.5 GPM aerators.
Low flow shower heads were replaced at the College's athletic facility the Leonard Center.
