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 | 172,330,242 Gallons | 189,312,943 Gallons |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 67,358,148 Gallons | 156,000,015 Gallons |
Start and end dates of the performance year and baseline year (or three-year periods):

A brief description of when and why the water use baseline was adopted:
As a campus, we've been using 2010 as a baseline to measure our water reduction since 2013.

A brief description of the institution's water-related behavior change initiatives:
Since 2010, SJSU has undertaken several major projects to maximize the use of recycled water on campus.
- 2010 SJSU developed the Landscape Master Plan to convert campus plant palate to less-thirsty landscaping
- 2011 SJSU connected the Main Campus irrigation system to the recycled water system
- 2016 the Student Union and Campus Village 2 was connected their dual plumbing to the recycled water system
- 2016 SJSU converts the Central Plant Steam make-up water to recycled water.
In total, SJSU converted 60% of its previous potable water usage to recycled water, saving more than 100 million gallons of potable water a year.
A brief description of the institution's water recovery and reuse initiatives:
SJSU is a customer of South Bay Water Recycling (SBWR), a City of San Jose program. The University currently has 3 recycled water accounts with SBWR and uses the recycled water for Irrigation of South Campus Athletic field and Main Campus, Main Campus cooling towers, and uses for industrial applications. All toilet flushing in King Library uses non-potable water via dual plumbing. All new buildings have been constructed with dual plumbing to be recycled water connected ready.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
