    The City's Role in Water Efficiency

    City of Phoenix water treatment plant.

    For more than 117 years, the City of Phoenix has strategically planned for current and future water needs, taking a multi-pronged approach to secure an efficient and reliable water supply for all its customers and for generations to come.

    Phoenix’s water portfolio is diverse and exceeds the State of Arizona's water conservation requirements, reducing its reliance on groundwater to a minimum. The City has worked hard to develop sustainable water management practices and has been designated by the State of Arizona as having a 100-year assured water supply, affirming that at least 100 years of water is physically, legally and continuously available to serve the City's existing customers and additional growth.

    Additionally, the City of Phoenix maintains a Water Resource Plan that is regularly updated and revised every five years to make sure that optimal water supplies and infrastructure are available to meet current and future demands, especially in times of drought.

    In Phoenix, every drop counts. The City effectively recycles nearly 100% of its highly treated wastewater for use in agriculture, energy production, urban irrigation, aquifer recharge and riparian wetland maintenance. Sustainable growth and water conservation are part of Phoenix’s strategic planning.

    ​​​​​​​​​​Effective supply management, a well-diversified portfolio, and significant conservation achievements over the years have enabled Phoenix residents to enjoy a lifestyle abundant with high-quality water for drinking and other important uses. The City is prepared for the future and remains dedicated to delivering the water needed to meet demands.
