Water Reuse Controversy
Scottsdale abandons direct water reuse plans following political criticism over safety concerns.
Anonymous
Scottsdale, Arizona, abandoned plans to add highly purified wastewater directly to its drinking-water supply by 2027 after political criticism framed the proposal as unsafe “toilet to tap.” The city says its treatment process produces water that exceeds federal drinking-water standards, and less than 1% of its wastewater comes from toilets; the council instead shifted funding to a broad $100 million allocation for new water sources and supplies. The dispute has become an issue in a city council race, with one candidate backing reuse and two others raising safety and cost concerns. Water-reuse advocates warn the decision could undermine drought resilience as Colorado River supplies face cuts, and Scottsdale’s experience is seen as important to other Arizona communities considering similar facilities.
Key Points
1
Scottsdale already uses purified wastewater to recharge aquifers, which can later be drawn on when other water sources run low.
2
Scottsdale pioneered its wastewater recycling system in 1998, and the existing facility is large enough to serve 60,000 households.
3
Scottsdale’s experience is being watched by Arizona water officials considering at least four other wastewater-recycling facilities.
4
Bryan Cassens, an assistant senior director for Scottsdale Water, said, “It’s so important to protect and reuse water in the Southwest.”
