Scottsdale Water, Arizona, USA – Advanced Water Treatment Plant, Operating under permit (Demonstration plant) at Scottsdale Water Campus

In 2017, Arizona repealed its moratorium on Direct Potable Reuse, paving the way for advancements in water treatment technologies. Following this, the Arizona Department of Environmental Quality granted Scottsdale the first fixed facility operating Direct Potable Reuse permit in 2019, for small-scale demonstration purposes.

This permit encompasses the comprehensive Advanced Water Treatment processes of the full-scale water campus, augmented by a demonstration module that features additional advanced treatment methods.

Scottsdale Water utilises the Advanced Purified Recycled Water (APRW) to recharge local aquifers and plans to supply APRW directly to customers by 2032. Scottsdale is evaluating Advanced Water Purification as a potential long-term component of its diversified water portfolio. Staff is reviewing feasibility, infrastructure integration, projected demand, regulatory requirements, and budget considerations. A demonstration facility is being considered to support public outreach and process validation.

To facilitate public education and engagement, Scottsdale Water provides samples of advanced purified water at events and other community outreach initiatives.

Through extensive and innovative groundwater recharge practices (see Scottsdale Water Campus: 1 Operating), a diverse water supply portfolio, and a commitment to promoting conservation, Scottsdale Water is ensuring safe, reliable drinking water now and into the future.
