Optional Fields

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

In the past two years, BHSU has been concentrating efforts to manage irrigation efficiently.

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

The campus uses irrigation water instead of potable water for much of our irrigation needs. When the main pump is running in the well house we are getting straight water from the aquifer.

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

High efficiency plumbing fixtures and low-flow aerators have been installed on most buildings in campus.
