How’s the water?

Ensuring the water Denver Water delivers to 1.5 million people across the metro area every day is clean and safe is a quest the utility takes seriously. 

Denver Water collects water from across 4,000 square miles of mountain watershed and cleans the water at its three drinking water treatment plants for delivery to customers. 

The utility's teams regularly test the water at every step along the way — from the mountains to points around the city. 

Travel with Denver Water teams in the video below as they access remote mountain areas to collect and test water samples. 

Last year, Denver Water collected more than 58,000 water samples and conducted about 128,000 tests.

Those samples and tests are part of a year-round effort monitored by the Environmental Protection Agency and the Colorado Department of Public Health and Environment.

Denver Water’s 2026 Water Quality Report shows that your drinking water is safe and meets — or goes above and beyond — requirements set by the EPA and state health department.

The report also contains important information about the source and quality of your drinking water, including data from the dozens of sites we monitor across our collection system.
