Plumbing Manufacturers International (PMI) and the Alliance for Water Efficiency (AWE) today announced a joint partnership on a study to determine potential water savings that could be achieved by replacing older, inefficient toilets with high-efficiency models.

The “Saturation Study of Non-Efficient Water Closets in Key States” will focus on Arizona, California, Colorado, Georgia and Texas – all states that have recently experienced serious water shortages. The study will determine the number of non-efficient toilets that remain within the installed residential base of plumbing fixtures.

“We are pleased to partner with PMI on this important research project, which we hope will highlight the remaining number of inefficient toilets still in use in these five critically water-short states and how much water can be saved by their replacement,” said Mary Ann Dickinson, AWE’s president and CEO.

The study will be completed by the end of February 2017 and will be posted on the PMI and AWE websites.
