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 possible shortage on the Colorado River as soon as 2019 are cause for concern, but they are not unexpected. Arizona has been visionary in water management planning and policy. Phoenix area 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.
