Tucson seeking companies to design & build ‘toilet to tap’ facility
Tucson city officials are moving to advance a plan to turn wastewater into drinking water by seeking a company to design and build an advanced water purification facility capable of filtering 2.5 million gallons per day. … Last year, the Arizona Department of Environmental Quality passed new rules allowing municipal water officials to build so-called “toilet-to-tap” systems, treating wastewater to what officials called “very-high quality” water. In January, city officials and the U.S. Bureau of Reclamation officials signed an agreement to build the $86.7 million water-purification facility, scheduled for completion by June 2031.
