Tucson Water is committed to delivering safe, high quality water to our customers. Our extensive water quality program operates 24 hours a day, 365 days a year, to ensure that the water delivered to our customers is kept free from harmful contaminants.
An important part of our water quality commitment is the backflow prevention program. When a water line is connected to equipment containing a nonpotable substance, this is known as a cross-connection. Contamination may occur when water flows through a cross-connection from a nonpotable source, such as a sprinkler system or heating and cooling units, into the potable water system. This can happen through a process known as backflow.
There are more than 30,000 backflow prevention assemblies in use in the Tucson Water service area. The Arizona Department of Environmental Quality requires that each be tested annually. A list of Tucson Water-Approved Certified Testers is available on this website or by calling (520) 791-2650.
