Working together, we are One for WaterTM
AMWUA’s membership consists of ten large municipalities in Maricopa County, Arizona. Collectively, the population of the AMWUA municipalities is 3.7 million people—more than 50 percent of the state’s population.

Conservation & Efficiency
Living in a desert, Arizonans recognize that water is a limited and precious resource. We know we need to conserve and protect the water we have, stretching and preserving it for the future. We have embraced a culture of conservation, and it’s paying off. That ongoing commitment will help us weather the impacts of climate change, extended drought, and shortage.

Drought & Shortage
Extended drought and a shortage on the Colorado River in 2022 are cause for concern, but they are not unexpected. Arizona has been visionary in water management planning and policy. The AMWUA cities have prepared and invested to ensure reliable, sustainable supplies for their communities. Continued innovative water management strategies, investment, and forward-thinking policy will enable us to meet the very real challenges ahead.
Where we stand on the issues
Smart water policy and careful planning, investment, and management have enabled AMWUA’s members to build robust, reliable water supplies that support our communities and economy. It is imperative that we continue to address the issues in front of us to ensure the future viability of those supplies. Learn more about some of the issues we are working on:
