Stanford is responding to the drought by asking all water users to follow drought actions to achieve additional water savings.
- Irrigation on Faculty and Staff Housing ornamental landscaping and lawns may occur on Tuesday and Friday nights for even numbered addresses, and Monday and Thursday nights for odd numbered addresses (and those areas without an address), between the hours of 7:00 pm and 7:00 am. (except to ensure continued health of trees, perennial non-turf plantings and food gardens).
Irrigation of non-functional turf with potable water is prohibited in institutional and multifamily areas (unless supporting tree health). “Non-functional turf” is turf that is solely ornamental and not regularly used for human recreational purposes or for community events. Non-functional turf does not include sports fields and turf that is regularly used for human recreational purposes.
Irrigation (both domestic and lake water) on ornamental landscaping and non-functional turf may occur no more than two days per week. (for non-residential customers who irrigate via zone, irrigation of ornamental landscapes is permitted on more than two days per week, so long as each irrigation zone within an individual property is irrigated no more than two days per week.)
Asking that functional turf areas (both domestic and lake water) be stressed based on priority list as appropriate to achieve at least 15% reduction from 2019 use (e.g., non-varsity fields, fairways, lawns within malls/courtyards, etc.)
- Continue to comply with water waste prohibitions in place since 2014:
- Using potable water to wash sidewalks and driveways (except for health and safety needs);
- Allowing more than incidental runoff when irrigating turf and other ornamental landscapes;
- Using hoses without automatic shutoff nozzles to wash motor vehicles;
- Using potable water in ornamental fountains or decorative water features that do not recirculate the water;
- Irrigating turf and ornamental landscape during and within 48 hours following measurable rainfall.

Stanford Water History
Stanford has an extensive history of effective water conservation efforts. With different water supplies for campus, Stanford Water Resources and Civil Infrastructure is able to manage available resources to meet campus needs, while preserving ecological systems and vital resources for future generations. Majority of the athletic fields, the golf course, and campus landscaping are irrigated using the non-potable lake water system. Campus groups across the University have worked diligently to conserve water, achieving a 48% reduction in domestic water use from 2001 to 2021 even as campus grew.
Past and ongoing conservation projects include:
- Using lake water to irrigate majority of campus, conserving more than 1 million gallons a day of the limited, high‐quality potable water supply.
- Water efficiency standards in all new buildings
- Fixture retrofits throughout existing buildings
- Stanford Energy System Innovations reduced overall domestic water use by 18% in 2015
- Weather-based irrigation controllers installed throughout campus landscapes
- Stanford's two stormwater capture facilities captured 22 million gallons of stormwater runoff for non-potable irrigation during 2020-2021
- See more projects at our Fact Sheets and More page
Stanford Water Resources & Civil Infrastructure continues to accelerate multiple water conservation efforts:
- WaterSmart dashboard for detecting leaks and reaching top water users
- Outreach to the campus community through educational materials, webinars, and water use report cards
- New discount program for Rachio smart controllers
- Meetings with campus groups to identify additional savings, especially in outdoor landscaping
Drought in California
After two years of low precipitation, reservoirs across the state are at below average levels. Nearly all of California is now in severe to exceptional drought, according to the US Drought Monitor
California's climate is prone to large fluctuations in precipitation from year to year. Making water conservation a Stanford way of life ensures we are resilient to these inevitable water shortages and protects the ecosystems our water is sourced from.
Thank you for all your efforts to conserve water!
