Optional Fields
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.
New rain gardens were added with the construction of the new Theater building.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
In July 2019 we replaced (886) 2.0 & 2.5 GPM faucet aerators in buildings across campus with 1.0 & 1.5 GPM aerators.
In addition to the Leonard Center shower heads, in 2017 we replaced (266) 2.5 GPM shower heads in the residence halls and houses with 2.0 GPM shower heads
