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 | 210,436,507 Gallons | 254,594,822 Gallons |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 132,253,880 Gallons | 178,604,822 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:
We adopted the 2007-2008 baseline year because of the availability of reliable data in that year and the alignment with the start of MSU Climate Action Plan the following year.

A brief description of the institution's water-related behavior change initiatives:
A brief description of the institution's water recovery and reuse initiatives:
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
MSU has actively been evaluating faucet and shower head flow rates. Our standard is 1.5 gpm for shower heads and .5 gpm for faucets. We have replaced shower heads and faucets with new showerheads and faucet replacements or aerators in all residence halls. We have also addressed faucets in most academic buildings as well as the installation of low flow flush valves in urinals and water closets where applicable. Our ongoing water conservation efforts include the assessment of water closet replacements, addressing water use in athletic and sports facilities and additional hardware replacements campus wide. All new buildings include low flow fixtures as standard features.
