Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Medium to High

Total water use (potable and non-potable combined):
Performance Year Baseline Year
Total water use 799,879,021 Gallons 986,745,387 Gallons

Potable water use:

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

FY 05/06 was adopted as the baseline for the majority of sections to be consistent with previous STARS reporting. For Water Use, data is reported by Calendar year to be consistent with regulatory reporting.

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:

The monthly AIR sustainability e-newsletter for Green Team members and others includes occasional tips on water conservation among its topics. In addition, the Green Paws office certification program includes water-related behavior change measures in Levels 1 and 4.


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

Penn State has masterplanned a Campus Reuse System for University Park that could reduce groundwater withdrawals by 300,000 to 500,000 GPD. It has started to install the distribution piping system one pipe section at a time as opportunities present themselves. And it is designing the interior plumbing systems of selected building projects for ease of reuse connection in the future. In summary, 24,000 feet of future reuse piping has been installed, nearly 5 miles, over the past 8 years.


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):

Retrofits that include high efficiency pluming fixtures and fittings are part of the Energy Program. Projects have been implemented at various locations on campus including many residence halls.

Vegetative grounds acreage derived from total campus acreage minus calculated impervious surface (using GIS).

Total water use comes from annual water withdrawal report. Potable water use comes from metered use.
