Municipal Separate Storm Sewer System (MS4) Permit

The Stormwater Enterprise manages the City's Municipal Separate Storm Sewer System (MS4) Permit Program. The stormwater permit addresses stormwater quality with an emphasis on controlling and limiting pollutants to the City's drainage system through control measures. Maintenance of the City of Colorado Springs' stormwater drainage is performed by the City's Operations and Maintenance Division. Crews perform a variety of tasks including cleaning of inlets, catch basins, and pipes and removal of debris from inlets, culverts, and channels. In addition, crews repair and stabilize stream banks.    

“The City is required to meet the requirements of the MS4 permit. If you observe failures to implement the permit please notify the Stormwater Enterprise at 719-385-5980 or utilize the GoCOS! app.”
