Storm Water Management
Storm drains are separate from the sanitary sewer system and polluted waters flow directly into local creeks waterways. To protect the quality of our streams and public health, report illicit discharges. Anything entering the storm sewer system that is not 100% storm water is an illicit discharge and is expressly prohibited from entering the system by the City of Allen.

Under the authority of the Clean Water Act, the Environmental Protection Agency (EPA) developed a storm water permitting program with the goal of significantly reducing the pollution source. The City of Allen has been designated by the EPA as an urbanized area and therefore must make application to discharge storm water to waters of the United States.
