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 | 39,463,732 Gallons | 90,573,076 Gallons |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 39,463,732 Gallons | 90,573,076 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, 2017 | June 30, 2018 |
A brief description of when and why the water use baseline was adopted:
We selected fiscal year 2017-2018 because we have a reliable data set and 2020-2021 because it is the most recent complete data available at the time of reporting.

A brief description of the institution's water-related behavior change initiatives:
SF State's response to the California ongoing drought has changed how and what the campus plants. The campus chooses native and adaptive plants anytime a new area is planted as they usually only need to be watered for the first couple of years after they are planted. SFSU installed an evotranspiration based watering system across campus. Facilities responds to any leak reports from its water company immediately by assigning work orders to plumbers when a leak notice is emailed to campus staff. Most of the academic buildings and the housing buildings have been retrofitted with low flush toilets and low flow fixtures.
A brief description of the institution's water recovery and reuse initiatives:
The Mashouf Wellness Center is LEED Platinum and uses greywater recycling to water the native and adaptive plants around the building. The building also has purple pipes for greywater reuse.
Our campus has a strong commitment to onsite rainwater management. We are required by the City and County of San Francisco to keep 75% of rainwater on site. This is required at new construction sites. We have built and designed five buildings in the last 10 years and all adhere to this rainwater ordinance. We usually achieve this through rainwater gardens and bioswales. We have extended our bioswales projects across many areas of campus to keep water on site and to help support the groundwater aquifer.
The building is surrounded by bioswales and rain gardens that absorb rainwater, utilizing it for irrigation and groundwater instead of sending it into storm drains.
New buildings are required to have plumbing for greywater systems and SF State's Campus Master Plan includes an on-site water recycling plant and a target of net-zero potable water demand.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
Our campus standard for all new plumbing fixtures specifies low flow toilets, faucets, showers, and other equipment. The campus has undergone water efficiency audits and retrofits on some buildings.
