Water Quality - Permits


Welcome to the Permits Section web page. We issue permits for discharges
of pollution to waters of the state, including groundwater. Our job is to
ensure that the permits we write and issue are protective of the uses of
those waters, like drinking water, aquatic life, agriculture, and recreation.

Here is a quick overview of how permits work in Colorado.
