Study: 170-billion-gallon water savings per year via water-efficient toilets

The "Saturation Study of Non-Efficient Water Closets in Key States" focused on Arizona, California, Colorado, Georgia and Texas. 40 out of 50 states anticipate water shortages in the coming years, according to a Government Accountability Office survey. The AWE/PMI study demonstrates that current plumbing technology can make a tremendous water-saving impact.

CHICAGO, IL — Water-efficient toilets could potentially save up to 170 billion potable gallons of water per year across five states facing water scarcity, according to new research released today by the Alliance for Water Efficiency (AWE) and Plumbing Manufacturers International (PMI). The “Saturation Study of Non-Efficient Water Closets in Key States” focused on Arizona, California, Colorado, Georgia and Texas – all states that have experienced serious water shortages.

The savings projected by the study (170 billion gallons of potable water yearly or 465 million gallons saved per day) could be achieved if non-efficient toilets in residential properties are replaced with water-efficient ones. This five-state savings can be extrapolated to an estimate of up to 360 billion potable gallons of water per year saved nationally. This research produces important direction for water managers nationwide, as 40 out of 50 states anticipate water shortages in the coming years, according […]
