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

The university is working to increase the proportion of irrigation water that comes from non-potable sources. Portions of the campus are served by the South Boise Water Company, which delivers irrigation water from the Boise River through a network of canals and culverts. BSU is working to extend this network to convert additional builidngs from potable to non-potable irrigation service.


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

Sawtooth Hall, a residential dorm, has a greywater reclamation system that diverts greywater for irrigation purposes.


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

Current water billing practices do not provide insight into which water meters are associated with irrigation use vs. non-irrigation use. Conversations are underway with the water utility to make the billing more transparent.

Additionally, considerable portions of the campus are irrigated with non-potable water sourced from the Boise river through a local canal company. This water is not billed on volume, but rather based on the amount of land & water rights held by the university. This non-potable irrigation water is not currently metered and is excluded from the reported totals. Diverted water that is not used by irrigation district shareholders is returned to the Boise river.

The university does not currently track total acres of vegetated grounds, but intends to begin tracking this metric.
