Water Quality

Tucson Water provides safe drinking water that complies with all federal, state, and local drinking water regulations. Our staff work together to monitor drinking water quality at 170 wells, 60 reservoirs, 271 sampling stations, and 125 selected homes across all our systems.

Hard water describes water with high levels of dissolved minerals. Between our local groundwater and the water from the Colorado River, the water we serve tends to be hard which can give it a different taste, however, it does not present any health risks. Learn some tips and tricks for managing Hard Water.

If your water looks cloudy, it may be due to millions of tiny bubbles mixed in with the water when it is released from the faucet. If it is discolored, it may be impacted by nearby construction.

Odors from your sink likely come from bacteria growing in the sink drain or water heater. “Chemical” smells may also be a result of the way Tucson Water disinfects water before it enters our system. Learn about water Odor for tips to prevent smell or learn about our water Disinfection.

Water Pressure can vary across our service area and even between nearby customers. It may be impacted by nearby construction, a malfunctioning pressure regulating valve, or leaks within the Customer Zone.
