FAQ: Bathroom water savings
Q. Exactly how much water do I save by using the new green-handled low-flow toilets and urinals correctly?
A. Old style toilets use anywhere from 2.8-3.5 gallons of water with each flush. Frequently, this wastes water without serving any real purpose. With the new dual-flush toilets installed in buildings around campus, each low flush (pushing the green, anti-bacterial treated handle up) uses only 1.4 gallons of water per flush. This saves from 1.4- 2.1 gallons per low flush.
The new pint-flush urinals save even more water than the dual flush toilets. An ordinary urinal uses one gallon of water per flush. These new urinals cut water use by 87.5 percent compared to traditional urinals.
In addition to these new toilets and urinals, the university also widely employs low flow shower heads. These shower-heads use only 60 percent of the water of regular flow shower heads, without impacting the quality of the shower at all.
