Dual Flush & Sensor Based Toilets

Dual-flush toilets have been used in Europe for decades to conserve water and are quickly gaining popularity in the United States. Unlike traditional toilets that use 3.5 gallons of water per flush, dual-flush toilets use a full 1.6 gallon flush for solids and 1.1 gallons for liquids.

Dual-flush toilets can be found in around 25 locations on campus and throughout all 47 floors at 33 Harry Agganis Way (Student Village 2).

“We’re trying these out in our premiere Student Village dormitory on campus,” says Bill Walter, assistant vice president of Facilities Management & Planning. “We’re going to continue to evaluate this technology to see how we can integrate this as we go forward, how they’re received by the students, and how well they function.”

Sensor based, or auto-flush toilets, are ubiquitous around Boston University. They consistently use 1.5 gallons of water, are more sanitary as there are no handles to touch, and ensure that toilets are always clean for the next stall visitor. They operate using an infrared light.
