Located in northern Phoenix, the Cave Creek Water Reclamation Plant (CCWRP) Rehabilitation Project is going to bring a new and renewable source of purified drinking water to Phoenix water customers. Between​ 2000 and 2008, the plant delivered recycled water to parks and golf courses before being closed due to a drop in demand in the region. By 2027, the next generation of this plant will produce nearly 7 million gallons of purified water each day which is enough water to serve 25,000 households. The water will be used to supply the City’s recycled water customers for parks, schools, and golf courses, as well as to recharge groundwater. Groundwater recharge occurs when water seeps into the ground to replenish underground aquifers for later use. This project is setting the stage for similar projects planned in the region.

How AWP at the CCWRP Works

Reverse Osmosis and Ultraviolet Advanced Oxidation are added to the improved CCWRP water recycling processes to destroy pathogens, remove chemicals, and disinfect the​​ water to bring the water to drinking water standards.​

Why Advanced Water Purification (AWP) Matters for Phoenix​

Phoenix relies on surface water for approximately 98% of its supply, primarily from the Colorado, Salt, and Verde Rivers, delivered through an extensive canal system. While groundwater serves as a backup, the city has made significant strides in water conservation, reducing overall demand even as the population grows.

However, climate change and prolonged drought threaten the reliability of surface water supplies. To ensure long-term sustainability, Phoenix is investing in Advanced Water Purification (AWP) to create a local, renewable water source that is independent of river flows.

Benefits of AWP:
  • Diversify Phoenix’s water portfolio, reducing reliance on unpredictable surface water supplies.
  • Increase resilience against future drought conditions and shortages.
  • Provide a high-quality, purified water source using cutting-edge technology to meet or exceed drinking water standards.
With AWP, Phoenix is taking a proactive approach to water security, ensuring safe, reliable water for generations to come.
