The city of Phoenix provides drinking water to more than 1.5 million people within our 540 square-mile service area. On average, about 95 percent of Phoenix's water comes from surface water (lakes and rivers). The remaining water comes from groundwater (wells). Phoenix is committed to providing the highest quality drinking water and service to our customers.
More than five million tests and measurements are conducted each year to ensure high quality tap water in Phoenix. It is tested for more than 100 substances. It is monitored throughout the year. Monitoring ensures water meets rigorous standards. The standards are set by the U.S. Environmental Protection Agency, Arizona Department of Environmental Quality, and Maricopa County Environmental Services.
Each May, the city distributes and posts to the web a Water Quality Report. It contains important information about the quality of your water.
