40 Important Ways that Colleges Are Conserving Water

21. Using cisterns

Colleges are using cisterns to harvest rainwater. At Harford Community College, they capture rooftop runoff in an 80,000 gallon cistern to use in an evaporative cooling tower.

22. Leak reporting

Dripping faucets can waste more than 600 gallons a year, and running toilets waste more than 131,000 gallons. On many college campuses, students, faculty, and staff are encouraged to report any leaks that they see. Doing so can alert the maintenance staff to undiscovered sources of water waste that can be resolved easily.23. Hand sanitizer installation

Duke University and many others have cut down on water used for sanitation purposes by installing hand sanitizers in bathrooms and other common areas. For quick sanitation purposes, a full hand wash using water is not needed, and alcohol-based sanitizer can be used instead.

24. Smart flushing

In addition to low flow and dual flush toilets, schools are updating with automatic eye flushers. These toilets flush according to the length of time a person is sitting on it, with a 1.1 gallon flush for less than 65 seconds, and 1.6 for 65 seconds or more.

25. Laundry education

Tufts reminds students to practice sustainable laundry techniques. Using a flyer, students are educated on using cold water options for washing clothing.

26. Increased irrigation ponds

At Duke University, they are taking advantage of more natural water storage by increasing the size of irrigation ponds on their golf course. This water can be used for toilets, landscaping, and more.

27. Water free urinals

Many colleges, including Vanderbilt University, are installing water-free urinals, which do not flush. Instead, the urinals use liquid chemicals and gravity, saving up to 40,000 gallons of water each year.

28. Water use monitoring

Enhancing awareness of water usage can help conservation efforts, making those who consume water more careful in their usage. Several colleges, including UC-Santa Cruz, have shared water use data publicly and within their community to spotlight conservation of water.

29. Watering at night

At lots of schools, watering was completed manually during the daytime, but more recently, colleges have implemented smart irrigation systems that water during the evening or early morning hours, saving evaporation, as well as overspray.

  1. Saving water is great, but there is another less recognized benefit of these projects. By implementing more efficient systems, the students get first hand experience of how small changes really add up. In fact, just by immersing them in it, you influence their mindset and change their views. Who knows, we might see the next big innovation coming from a student who thought of an even more efficient method!
