Accounting for Every Drop and Minimizing Water Loss
Behind the clean, safe water that flows from your tap lies a vast, complex system—a network of technology, logistics, and engineering designed for reliability. Once your water provider treats that water to the highest standards, an essential part of the process begins: a sophisticated tracking system designed to monitor every single drop the utility produces. ...

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.

Colorado River Shortage
The river is producing less water due to drier and warmer conditions in the basin, which are reducing runoff from snowpack. In the last century, the river was allocated to deliver 16.5 million acre-feet among the seven Colorado River Basin States and Mexico. However, the river is now only producing 12.4 million acre-feet and could decline by an additional 20%.
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:
