Water reuse purification facilities are popping up all over the world and some communities have used reuse water for more than four decades. Potable reuse in the U.S. Locally, Aurora began using reuse water in 2010 with the installation of the Prairie Water project which supplies 50 million gallons of potable reuse water per day to Aurora and surrounding communities. (Some of our WISE water is from Prairie Waters.) It is estimated that by 2065 almost 30% of water consumed in all South Metro communities will be from reuse.
