About Mesa
Mesa is a city in Maricopa County, in the U.S. state of Arizona. As a suburb located about 20 miles east of Phoenix, it is the third-largest city in Arizona by population.
Water Situation
Mesa's tap water comes primarily from the Salt River Project and the Colorado River, which are treated at local water treatment plants. The city's water generally contains minerals like calcium and magnesium, but it's treated to meet federal safety standards. Over time, the city has invested in advanced purification processes to maintain high water quality standards.
