Water Quality

Water is our most precious resource. As the largest private water utility in Arizona and New Mexico, we understand the obligation we have to protect our more than 360,000 customers.

We test water in our systems daily, and adhere to stringent federal and local guidelines, including checking at various stages of its cycle from wells and canals to the tap itself to ensure that you and your family are drinking safe water. It's a process our skilled analysts and scientists repeat 21,000 times a year to make sure water meets our standards.
