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

We've been routinely replacing fixtures with low flow equivalents in all renovation projects. We only irrigate athletic fields.


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

The campus garden collects rainwater for irrigation (although, due to the size of the garden, the majority of the water comes from a high-efficiency drip-irrigation system).
Detention areas use the physical features of the campus to store water. There are three detention areas on campus, one behind the Warch Campus Center, one at the end of Boldt Way and a third behind Hiett Hall and by the apiary.
There is also underground water storage under the Banta Bowl and it takes the water and runs it to the river. Only new plantings are watered on campus until they are well established.


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

Fixtures are replaced up to code during renovations.
