Water & Wastewater Treatment

Water Treatment

Scottsdale’s Water Resources Division works around the clock to ensure safe, reliable drinking water is there for you whenever you need it. We operate three state-of-the-art water treatment facilities that meet or surpass all federal, state and local water quality standards. 

Scottsdale’s water supply comes from both surface and groundwater sources, depending on the time of year; you may receive water from a single source of water or a combination of water sources.

The main water supply is the Colorado River which is transported to us from the Central Arizona Project (CAP) Canal to our Water Campus. Our Chaparral Water Treatment Plants receives water from the Salt and Verde rivers through Salt River Project (SRP) canal system. Scottsdale also uses a small amount of groundwater to supplement our water supplies from time to time.  

Scottsdale also operates the Central Groundwater Treatment Facility (CGTF) to treat water that comes from the North Indian Bend Wash, an EPA designated Superfund site.

No matter where your water comes from, it is all treated to levels better than what the federal and state mandate for drinking water standards.

Although the water treatment process varies slightly at each of our facilities, the basic process is the same.  

Wastewater Treatment

Scottsdale has one of the most sophisticated water reclamation systems in the country and we work around the clock so everything that goes down the drain - stays down the drain.  The highly treated effluent that leaves our reclamation plant is reused to irrigate more than 22 different golf courses in the central and northern part of the city.

Operators for both our Water and Reclamation Services are required to be certified by the Arizona Department of Environmental Quality, and are required to obtain thirty hours of Professional Development training to renew their certifications, which is required every 3 years.
