Every time it rains, water runs off the land as stormwater. Other forms of precipitation, such as melted snow and ice also are stormwater. Stormwater flows over rooftops, lawns, driveways, streets, and into the nearest storm drains and/or drainage ditches.

Anything dumped or dropped on the ground or in the gutter can end up in the nearest body of water. Stormwater systems were originally intended to route rainwater quickly off the streets during a heavy storm. Unfortunately, these systems can carry pollutants through city streets and straight to our waters. Unlike the water that goes down a sink or toilet in your home, stormwater is untreated and flows directly into our local streams and rivers.

Examples of pollutants that threaten our waterways are fertilizers and pesticides, soaps and detergents, vehicle fluids (motor oil, gasoline, anti-freeze), silt and sediment, pet waste left on the ground, paints, grease, sewage, trash, and other debris. Stormwater pollution results from materials and chemicals washed into the storm drains from streets, gutters, neighborhoods, industrial sites, parking lots and construction sites.


In June of 2017, Hannibal’s City Council Members approved the Hannibal Board of Public Works to create a stormwater utility to address areas in which the storm sewers’ infrastructure is failing. Along with listing and prioritizing known issues to be repaired, the Stormwater Department is now responsible for state permitting requirements, system planning, and all future replacement and maintenance.

At the September 2017 Board meeting, The HBPW’s Board of Director’s approved a contract with the engineering firm Black and Veatch for designing a sustainable funding source.

The Stormwater Department is currently working diligently in formatting a new Stormwater Management Plan to submit for Missouri Department of Natural Resources approval. It will be due July 1st, 2018.  This plan will be subject to public review before its submission. Click on the links below to view the previous plan put in place by the city of Hannibal.

It is the department’s intent to keep the public educated and informed as this utility develops. A knowledgeable community is crucial for a successful stormwater management program. We will continually post updates, or you can email your questions to the Stormwater Department HERE
