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 | 66,918,431 Gallons | 77,226,164 Gallons |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 66,918,431 Gallons | 77,226,164 Gallons |
Start and end dates of the performance year and baseline year (or three-year periods):
| Start Date | End Date | |
| Performance Period | July 1, 2019 | June 30, 2020 |
| Baseline Period | July 1, 2007 | June 30, 2008 |
A brief description of when and why the water use baseline was adopted:
We are using updated data provided by the Town of Middlebury who supply our water. We do not have data available to distinguish potable from non potable. Facilities estimates that in any given year about 2 to 5% of the water we use is for irrigation depending on the weather and any projects that require revegetation work. Potable water is used for human consumption and hygiene, food prep, cooling equipment, steam production, etc. A relatively small portion of the total is for direct human use.
