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

2005 was the year we've used in past reports.

We don not have solid numbers for the 2005 "Vegetated grounds" acreage. We imputed a conservative estimate.

A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

Every water bottle refill station has an education sign on it designed by students.
The Eco-Reps (sustainability liaisons in each resident hall) dedicate at least one month a year to water conservation


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

The University taps into the City of Flagstaff's reclaimed water system for the majority of its landscaping irrigation and some of its toilet water usage.


A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

Most of campus water fixtures were changed out in 2012. Low flow toilets, shower heads and aerators were installed and are now our campus standard.
