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 | 82,240,505 Gallons | 94,660,635 Gallons |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 77,098,900 Gallons | 94,660,635 Gallons |
Start and end dates of the performance year and baseline year (or three-year periods):
| Start Date | End Date | |
| Performance Period | July 1, 2020 | June 30, 2021 |
| Baseline Period | July 1, 2007 | June 30, 2008 |
A brief description of when and why the water use baseline was adopted:
The baseline of the fiscal year 2008 for water usage was adopted to keep the numbers consistent with Bucknell's Comprehensive Environmental Assessment conducted and completed in 2008. This comprehensive report is the most recent document that measures all aspects of Bucknell's campus with respect to sustainability. It was also adopted to keep the baseline used for all other reporting sections consistent.

A brief description of the institution's water-related behavior change initiatives:
The University continues to invest resources into water conservation and efficiency particularly through the Green Fund revolving loan fund mechanism for sustainability projects. Water consumption is down approximately 15% over the prior performance year. The development of a comprehensive water conservation and efficiency management plan has been a part of the success story.
A brief description of the institution's water recovery and reuse initiatives:
Condensate from gas turbine inlet cooler is recovered and used in cooling towers.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
At the campus operations level, we continue to invest resources into water conservation and efficiency through the Green Fund revolving loan mechanism for sustainability projects. Water consumption is down approximately 23% from the baseline year 2008 while the student population and building SQT continue to grow. A comprehensive water conservation and efficiency management plan has been developed. Money from the Green Fund is used to implement specific projects. Fixtures were replaced in one residence hall (Smith) and one affinity house (SPE) in FY21.
