Nogales 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 no potable substance, this is known as a cross-connection. Contamination may occur when water flows through a cross-connection from a no potable 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 300 backflow prevention assemblies in use in the Nogales Water service area. The Arizona Department of Environmental Quality requires that each is tested annually. A list of Nogales Water-Approved Certified Testers is available on this website or by calling (520) 285-5733.
