Scottsdale can do it. Phoenix is studying it. But no water provider in Arizona is actively cleaning up wastewater to include in drinking water it is supplying to homeowners and businesses.
The reason is because there is not a set of government guidelines in place for the setup and process. However, that could soon change.
The Arizona Department of Environmental Quality is undergoing a rulemaking process that will create a set of guidelines for the state’s water providers. This process, with a staff-stated goal of having rules in place by June 30 of next year, will guide providers through the process of purifying wastewater for drinking.
