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 has three drinking water treatment plants that clean the water for delivery to customers. (Click here to check out the construction on the utility's newest plant.)

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 55,000 water samples and conducted more than 200,000 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 2024 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.
