A brief description of when and why the water use baseline was adopted:

Before 2018 we did not have sufficient data to satisfy this category. We now have the ability to get accurate data in regards to all water used, (Excluding Irrigation) but do not have a way to segregate system makeup water.

Optional Fields

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

The campus does a lot of xeriscaping in the new/renovated areas on campus. The plants thrive in desert like ecosystems and are more efficient for water use.

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

Not applicable at this time.

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

All equipment associated with all systems gets replaced by high efficient replacements.
