By conducting building water audits, fixing leaks and installing low-flow fixtures, the university has reduced potable water use by nearly 29% — by 379 million gallons — since 2015. In 2021, the university increased its reduction target to 10% from the original 5% per capita by 2025.
Home to more than 100,000 students, faculty, staff and visitors each day, Ohio State is comparable to a medium-sized city. The university uses more than 1.3 billion gallons of water per year — enough to fill Ohio Stadium more than 3.5 times. Ohio State aims to further increase water efficiency by making infrastructure improvements and reducing water consumption.
Additional accomplishments and initiatives
- In fiscal years 2018 and 2019, the university used acoustic leak detection technology and fixed two leaks in its water main shutoff valves, resulting in an annual savings of 50 million gallons.
- The university conducts ongoing audits of water use in 10 to 20 campus buildings per semester.
- College of Pharmacy lab changes reduced once-through water, or water used only one time and then disposed of, resulting in a savings of 16 million gallons annually.
- Low-flow fixtures are being installed in restrooms across campus. Student Life replaced 4,788 showerheads and 225 faucets in the summer of 2019.
- Continued education and communication from Facilities Operations and Development helps the campus community learn about water consumption.
Water Consumption Baseline (2015):
