Municipal Separate Storm Sewer System (MS4)
Stormwater from our community is transferred directly from our inlets and ditches to our lakes, streams, and rivers. Stormwater effectively accumulates and transfers pollutants. Most of these pollutants are efficiently stopped by following preventive measures and avoiding these sources of stormwater pollution:

• Changing motor oil on impervious driveways
• Improperly disposing leftover paint and household chemicals and lawn chemicals
• Leaking trash containers
• Littering
• Operating vehicles that leak fluids
• Pet waste
• Washing cars on pavement

Citizen cooperation is necessary to ensure that the City of Columbus is doing its part to make our nation a beautiful and safe place for future generations.
