Level of ”Physical Risk Quantity” for the institution’s main campus as indicated by the World Resources Institute Aqueduct Water Risk Atlas:
Total water withdrawal (potable and non-potable combined):
| Performance Year | Baseline Year | |
| Total water withdrawal | 1,736,757,696 Gallons | 695,680,350 Gallons |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 200,365,264 Gallons | 184,770,960 Gallons |
Start and end dates of the performance year and baseline year (or three-year periods):
| Start Date | End Date | |
| Performance Period | July 1, 2018 | June 30, 2019 |
| Baseline Period | July 1, 2004 | June 30, 2005 |
A brief description of when and why the water use baseline was adopted:
We have chosen to use 2005 as our baseline year for as many of the utility data credits as possible. Since we submitted our first STARS report in 2014 and used 2005 as our baseline year, we want to stick with it. This aligns with our GHG reporting as well.
Figures needed to determine "Weighted Campus Users":
| Performance Year | Baseline Year | |
| Number of students resident on-site | 2,418 | 2,762 |
| Number of employees resident on-site | 4 | 4 |
| Number of other individuals resident on-site | 0 | 0 |
| Total full-time equivalent student enrollment | 10,487 | 11,695.45 |
| Full-time equivalent of employees | 2,778 | 2,372 |
| Full-time equivalent of students enrolled exclusively in distance education | 1,144 | 0 |
| Weighted campus users | 9,696.25 | 11,242.09 |
Potable water use per weighted campus user:
| Performance Year | Baseline Year | |
| Potable water use per weighted campus user | 20,664.20 Gallons | 16,435.65 Gallons |
Percentage reduction in potable water use per weighted campus user from baseline:
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area | 3,780,036 Gross square feet | 3,724,191 Gross square feet |
Potable water use per unit of floor area:
| Performance Year | Baseline Year | |
| Potable water use per unit of floor area | 53.01 Gallons per square foot | 49.61 Gallons per square foot |
Percentage reduction in potable water use per unit of floor area from baseline:
Area of vegetated grounds:
| Performance Year | Baseline Year | |
| Vegetated grounds | 366.31 Acres | 366.31 Acres |
Total water withdrawal per unit of vegetated grounds:
| Performance Year | Baseline Year | |
| Total water withdrawal per unit of vegetated grounds | 4,741,223.82 Gallons per acre | 1,899,157.41 Gallons per acre |

A brief description of the institution's water-related behavior change initiatives:
The University of Montana really hasn't developed or implemented any water-related behavior change initiatives.
A brief description of the institution's water recovery and reuse initiatives:
UM uses non-potable water for all of our groundwater cooling systems. In Gallagher, the building that houses our College of Business, we use HVAC ground water (captured in a cistern) for irrigation. We also relocated a data center on campus that was using potable water for cooling to a new location that resulted in saving 8,409,600 gallons of water a year.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
Facilities services strives to remove all pump-and-dump cooling systems whenever possible and replace them with more water-efficient cooling options.

Data source(s) and notes about the submission:
Data for potable and non-potable water use is attached. Ground water cooling and irrigation are both non-potable and include the UM-owned golf course. The only potable water is water use in buildings.
