The Drainage system in Columbia County must be kept clean or flood risks may increase. Debris (even grass clippings) in ditches, storm drains, and streams may obstruct the flow of water and cause overflow into streets, yards, and homes. Columbia County's Ordinance Section 34-148 makes it illegal to dump debris into any part of the county's storm sewer system, which includes storm drains, ditches and waterways. If you see any violations, please contact the Columbia County Customer Help Desk at 706-868-3375.
