Scottsdale halts purified wastewater recycling plan

The Scottsdale City Council has halted a plan to deliver purified recycled water directly to residents' taps following political opposition. The decision follows unproven claims by candidates regarding water contamination, which city officials noted marginalize the science of the treatment program. Water officials clarified that less than 1% of the city’s liquid waste originates from toilets.

In June, the council replaced specific funding for the recycling program and other water projects with a $100 million allocation for unspecified new water sources. This budget change effectively ended a plan to integrate purified wastewater that exceeds federal drinking water standards into the local supply by 2027.

The program has become a central issue in the upcoming November election for two city council seats. While one candidate supports wastewater integration, a conservative incumbent and a former Republican state lawmaker have expressed skepticism regarding the safety and costs of meeting new state regulations. Experts warn that reducing wastewater reuse could weaken regional water resilience as the American West faces ongoing drought and reduced flows from the Colorado River.
