Water Quality


Tucson Water sources its potable water from local aquifers and from annually refreshed water on the Colorado River. The factors that dictate the makeup of the water from your tap depend on this blend which can vary across our service area. For the safety of our community, Tucson Water employs a robust water quality monitoring program that goes above and beyond state and federal regulation, protecting the water we deliver every day.

Frequently Asked Questions

Is my water safe to drink?

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.

What is hard water?

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.

Why isn't my water clear?

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.

Why does my water smell or taste bad?

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.

Why is my water pressure low?

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.
