Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Total water use (potable and non-potable combined):
| Performance Year | Baseline Year | |
| Total water use | 655,457,000 Gallons | 818,738,000 Gallons |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 655,457,000 Gallons | 818,738,000 Gallons |
Start and end dates of the performance year and baseline year (or three-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2017 | June 30, 2018 |
| Baseline Year | July 1, 2016 | June 30, 2017 |
A brief description of when and why the water use baseline was adopted:
Water baseline is from fiscal year 2016-2017, this was adopted because it was the most recent year without a focus on water sustainability and had comparable number of campus users to this recent year. This was also the fiscal year before a full-time sustainability coordinator was hired in 2018.
Figures needed to determine "Weighted Campus Users":
| Performance Year | Baseline Year | |
| Number of students resident on-site | 2,689 | 2,671 |
| Number of employees resident on-site | 24 | 26 |
| Number of other individuals resident on-site and/or staffed hospital beds | 14 | 22 |
| Total full-time equivalent student enrollment | 3,918 | 4,195 |
| Full-time equivalent of employees (staff + faculty) | 845 | 842 |
| Full-time equivalent of students enrolled exclusively in distance education | 0 | 0 |
| Weighted campus users | 4,264.50 | 4,474 |
Potable water use per weighted campus user:
| Performance Year | Baseline Year | |
| Potable water use per weighted campus user | 153,700.79 Gallons | 182,999.11 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 | 2,511,298 Gross square feet | 2,438,268 Gross square feet |
Potable water use per unit of floor area:
| Performance Year | Baseline Year | |
| Potable water use per unit of floor area | 261.00 Gallons per square foot | 335.79 Gallons per square foot |
Percentage reduction in potable water use per unit of floor area from baseline:
Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):
Area of vegetated grounds:
| Performance Year | Baseline Year | |
| Vegetated grounds | --- | --- |
Total water use (potable + non-potable) per unit of vegetated grounds:
| Performance Year | Baseline Year | |
| Total water use per unit of vegetated grounds | --- | --- |
Percentage reduction in total water use per unit of vegetated grounds from baseline:
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:
Signage is posted in bathrooms, laundry rooms, residential areas and others promoting limited and smart water use.
A brief description of the institution's water recovery and reuse initiatives:
Our irrigation system is set on a timer and controlled in Facilities to ensure there is not over-watering or flooding. Only lawned areas are irrigated, primarily during the dry summer months.
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):
There have been major renovations to the cooling towers that significantly decreased overall college water use. Retrofits are constantly being done in bathrooms to update plumbing fixtures to efficient technologies.
