Investing in water infrastructure secures our future

Published May 14, 2024

Water systems are the most fundamental infrastructure within our communities as they ensure safe and clean water delivery to households, industries, and businesses. Millions of gallons of water move daily through miles of pipes buried under our feet. The water circulates through treatment plants, tanks, pumps, and miles of service lines that deliver water to our water meters and is there whenever we need it. All of which is not a simple feat.

Accomplishing this requires vast infrastructure systems that have been methodically built over the course of decades. Within the ten AMWUA municipalities, the collective infrastructure consists of 30 water treatment plants, over 18,000 miles of water lines, 142,000 fire hydrants, and more than one million water meters. All of which highlights the extent of infrastructure needed to deliver water every day of the year.

Clean and safe water is a precious commodity, and investing in pipelines, canals, treatment plants, recharge projects, and countless other technology upgrades is critical for securing our water future. Such investments ensure that Arizona’s water supplies remain clean and reliable. This is even more important than ever as water utilities face pressures on their water supplies impacted by our 30-year historic drought and Colorado River shortages.

Like transportation, telecommunications, and power - water infrastructure ages over time and eventually must be replaced. That is why maintaining and upgrading infrastructure is a continual priority for the AMWUA cities and all water providers. This includes making the financial commitment to invest in their water infrastructure's maintenance, replacement, and expansion, which has experienced rising costs impacted by the same inflation and supply chain issues that have affected other aspects of our economy.  

Maintaining aging and expansive water distribution and collection systems is an ongoing and growing expense for your city and is a significant component of your city’s water rates. Your city water professionals are continually fine-tuning how best to plan and fund for the timely replacement of this critical infrastructure so that expensive emergency repairs and customer service disruption are avoided as often as possible.

As we recognize Infrastructure Week - a national week of advocacy and education that brings together business, labor, and elected leaders to spotlight the need to revitalize, modernize, and invest in infrastructure – it’s essential to understand and appreciate infrastructure's critical role in the desert. Prioritizing investments in the rehabilitation or replacement of aging water and wastewater systems and building new infrastructure ensures the reliability and resiliency of our water now and for future generations.
