Water Quality

Fort Collins Utilities does not solicit water quality testing at homes or businesses, though some private companies do. Utilities' treated drinking water consistently surpasses state and federal standards.

If you have questions about water quality, read our 2019 Water Quality Report. You also can call Utilities' Water Quality Laboratory at 970-221-6863.


Fort Collins Utilities monitors water quality in three areas:

  • source waters (Upper Cache la Poudre River and Horsetooth Reservoir) — where our water comes from
  • treated drinking water
  • treated water that is returned to the environment and the Lower Cache la Poudre River above and below the water reclamation facilities

The watersheds where our water comes from consist of the large areas of land that drain snowmelt and rainfall waters to the Poudre River and the Big Thompson River, Horsetooth Reservoir and other components of the C-BT project. Watershed monitoring and protection involves minimizing the negative impacts to the quality of these waters from activities on both land and water.

Fort Collins' drinking water comes from the Cache la Poudre River and Horsetooth Reservoir and is treated at the Water Treatment Facility. It is distributed to homes and businesses in Fort Collins through 525 miles of water mains.

After wastewater is treated at the Water Reclamation Facilities to meet or exceed all state and federal pollution control standards, it is returned to the environment where it is collaboratively monitored to protect the Cache la Poudre River downstream.
