View the 2018-19 Sustainability Year in Review for more in-depth data on water use.
Key water conservation activities this year included the following:
- Continued to work with campus groups including the School of Medicine, Athletics, LBRE Grounds Maintenance, and Residential & Dining Enterprise to continue water conservation projects throughout campus.
- WP&S continued to pilot new low water use technology, including a dual-setting aerator that used between 0.06-0.3 gallons per minute, a savings between 85-98% when compared to traditional faucet aerators!
- WP&S Partnered with Athletics to test three low flow shower head fixtures. While testing the shower heads, we gathered locker room occupancy to better understand facility use. The results showed that showers lasted an average of five to seven minutes, depending on the locker room.
- Stanford began operating a new stormwater capture system. The fields at Sand Hill act not only as an area of recreation, but also as a giant stormwater detention basin to collect excess stormwater during rain events, rather than overwhelming the local creeks with runoff. Once the stormwater is collected, it is filtered and pumped to Felt Lake. The non-potable water from Felt Lake is then used to meet the majority of campus’s landscape irrigation demands. By Stanford implementing more regional stormwater controls like this detention basin, it will free up space around buildings for other purposes and allow Stanford to diversify their water supply by adding an alternative water supply.
- Stanford’s annual Water Wise campaign, which raised awareness about Stanford’s water systems and infrastructure and encouraged the campus community to participate in local Earth Week service opportunities, resulted in over 500 water conservation actions taken by nearly 200 community members through the My Cardinal Green platform. Additionally, 50 people volunteered time in the Arizona Garden and Stanford Foothills in the annual Service Day. For the first time, Stanford Water Stewardship & Planning’s team led a tour group of participants through Stanford’s Arts District to learn about stormwater facilities.
- WP&S expanded its interactive Water Conservation Program Map, detailing water conservation retrofit projects since 2002. Users can explore over 300 indoor and outdoor projects and water-efficient equipment upgrades, as well as estimated water savings where available. The map also includes general water profiles for each new university building opened since 2007.
- Stanford’s annual Water Wise campaign, which underscored California’s statewide “water conservation as a way of life” initiative, resulted in over 500 water conservation actions taken by nearly 200 community members through the My Cardinal Green platform.
- In Spring 2018, WP&S partnered with the Bay Area Water Supply & Conservation Agency (BAWSCA) to host two classes on creating water-efficient and low-maintenance gardens through the use of native and drought tolerant plants.
- WP&S partnered with the Stanford Green Labs program to fund the installation of 37 aerators throughout campus, expected to conserve over 190,000 gallons of water per year.
- The School of Medicine, a champion of water conservation and stewardship, converted nine standard irrigation controllers to weather-based irrigation controllers at four sites. In the first year after the conversion, these sites saw a reduction in irrigation water use of 45% compared to 2013.
- Building off a successful initial collaboration, members of Stanford Campus Residential Leaseholders and the Water Quality, Efficiency, and Stewardship (WQES) team partnered with OnPoint EcoSystems and the Santa Clara Valley Water District to conduct Phase 2 of the Residential Smart Irrigation Controller Pilot Study. Participants in Phase 2 saw a 38% reduction in water use during the study’s first year.
- Together with the Department of Athletics, Physical Education, and Recreation (DAPER), the Water Efficiency Program sub-metered a selection of pools to track water use patterns to better understand evaporation rates.
- In 2016, Stanford irrigated almost all of academic campus with non-potable irrigation water, and the majority of irrigation controllers use weather-based controls.
- WQES expanded its interactive Water Conservation Program Map, detailing water conservation retrofit projects since 2002. Users can explore over 300 indoor and outdoor projects and water-efficient equipment upgrades, as well as estimated water savings where available. The map also includes general water profiles for each new university building opened since 2007.
