What is stormwater?

Stormwater is water from rain or snowmelt events that does not infiltrate into the ground and flows across the land. Stormwater drains into a combination of underground pipes, inlets, drainage ditches, and ponds designed to collect, convey, and discharge directly into our local creeks and rivers (for example: South Platte River, Big Dry Creek, Clear Creek). Unlike indoor sanitary sewage drains, stormwater does not enter a wastewater treatment plant to be treated.

Stormwater may wash and carry pollutants such as trash, sediment, oils, antifreeze, heavy metals, bacteria, and fertilizers from sidewalks, streets, and parking lots, discharging them directly into our creeks and rivers. Stormwater pollution may pose an adverse toxic effect on aquatic life, plants, animals, and people. That is why Adams County Illicit Discharge Ordinance No. 11 makes it unlawful for any person to intentionally or accidentally allow any liquid or solid waste to enter the storm drainage system.

Please report any unauthorized substance entering the storm sewer system to: 720.523.6400 or e-mail [email protected] (call 911 for emergencies).
