Ensuring Water Resilience in the Desert: Inside Phoenix’s Treatment and Delivery System with Troy Hayes

Troy Hayes, Water Services Director for the City of Phoenix, Arizona, shares insights into the city’s water treatment and distribution system. Phoenix operates five water treatment plants, with two in North Phoenix (Union Hills and Lake Pleasant) utilizing Colorado River water delivered by the Central Arizona Project (CAP), while three central plants treat Salt River Project (SRP) water. CAP water can also be redirected to any plant during maintenance or drought. Troy details the city’s treatment process, robust water quality monitoring, and its 6,000-mile interconnected pipe system, which delivers an average of 264 million gallons of water daily. Deliveries are adjusted monthly to meet customer demand, influenced by factors such as weather, tourism, and usage patterns.
