COLUMBUS CITY UTILITIES
COLLECTION SYSTEM
The wastewater collection system consists of over 200 miles of pipeline and 45 pumping stations. The pipelines consist of a variety of material including brick, clay, cement asbestos and PVC plastic.
Approximately one third of the system is of the combined type, handling both sanitary and storm flows. The system has three points of combined sewer overflow which prevent the overloading of the treatment plant during heavy rain events. These 'CSO's' are the subject of ever increasing regulations. For more information on how Columbus is responding to these new challenges check out our CSO page at www.columbusutilities.org/cso .
Many pipes within the system are over 100 years old and require vigilant maintenance. Our crews have vacuum and hydraulic cleaning equipment and well as an in pipe video system to pinpoint problems.
Through regular maintenance schedules (based upon need) they keep everything 'flowing'.
There is an ongoing effort that requires customer support. Downspouts and foundation drains (including sump pumps) are not allowed to be directly connected to the sanitary sewers. These 'clean waters' use capacity in our lines as well as our treatment plant. Customers who wish guidance on how to remove these improper connections should contact our office.
