Scottsdale, an affluent suburb of Phoenix, has paused efforts to expand its water recycling program amid political and public debate, especially during the current election season. The city has long used purified wastewater to recharge underground aquifers, particularly during periods of water scarcity. However, concerns over the program’s safety and cost have led the city council to shift funding from the recycling initiative and other water projects to a more general $100 million allocation for new water sources. This decision has sparked controversy, particularly in the race for two city council seats, where differing views on wastewater reuse are shaping the campaign. The debate has become a major issue in the three-way race for the council seats. One candidate supports expanding the use of purified wastewater into the city’s drinking water supply, while a former Republican state lawmaker and a conservative incumbent have raised doubts about the program’s safety and cost. They have questioned new state regulations, which some water officials argue are unnecessarily complicating the process. The city has criticized claims that the program involves "toilet to tap" water as misleading, emphasizing that the treatment process is scientifically rigorous and that less than 1% of the city's wastewater comes from toilets. Scottsdale has been a pioneer in wastewater recycling since 1998, with a facility capable of serving 60,000 households. This expertise is valuable for other Arizona cities trying to implement similar systems. The city relies heavily on the Colorado River for 70% of its water supply, more than any other similarly sized city in Arizona or California. Water officials say this dependence, combined with population growth, has made recycling essential for managing drought risks. However, the recent budget shift and a council majority skeptical of wastewater reuse may weaken the city’s preparedness for future water challenges, especially as the West faces prolonged drought and significant reductions in Colorado River water allocations. Despite the political tension, Scottsdale’s water recycling facility continues to operate normally. The city plans to present new options to the council in October. Former state lawmaker Michelle Ugenti-Rita, a vocal opponent of the program, has used campaign ads to challenge her opponents, while incumbent Councilman Barry Graham has called the program costly and an overreaction to drought. Officials in Scottsdale, Phoenix, and Tucson have also criticized new state rules that require tracking non-federally regulated contaminants in purified water, saying they increase costs. The Arizona Department of Environmental Quality is working to simplify these rules but won’t finish until early 2027. As the Colorado River continues to decline, with Lake Mead and Lake Powell reaching record lows, the debate over water recycling in Scottsdale highlights a broader challenge across the West. Federal plans for the river system call for significant water cuts affecting over 25 million people through 2036. While federal agencies are investing in advanced water purification projects, public confidence in Arizona’s water future remains divided, with nearly half of voters expressing uncertainty about the state’s ability to meet future water needs.
