Morgan City runs annual sewer clean-out

Residents urged to take precautions


Morgan City has contracted with Twin D to clean the City’s sanitary sewer system.

Starting October 31st, 2017 and running for approximately the next three weeks Twin D will be in neighborhoods performing this task.

The sanitary sewer lines are cleaned using high performance sewer cleaning equipment. A cleaning nozzle is propelled from one manhole to the next using water under high pressure. The nozzle is then pulled back to the starting manhole. As the nozzle is pulled back, water scours the inside of the sanitary sewer pipe. Any debris in the pipe is pulled back with the water. The debris is removed from the manhole with a vacuum unit. If roots are found, they are cut with a root cutter. This process is repeated on every sewer line cleaned.

During cleaning of sanitary sewer lines, air occasionally vents into a home through the sanitary sewer service line and ventilation system. When this happens, water in the toilet bowl can bubble or surge or, in rare instances, splash out of the bowl. We remind you that the water that could come from this type of incident is from the bowl itself. Therefore during the three week period it would be beneficial to make sure to keep the lid of your toilet bowl down to minimize the water splashing from your toilet.

The common causes of air venting into homes during sanitary sewer cleaning are: air movement from normal cleaning operations, the use of higher pressure needed when cleaning sanitary sewer lines that have a steep slope, sewer lines running close to the building, a plugged roof vent, and the size and complexity of the home’s waste and ventilation system. To minimize water splashing out of your toilet bowl, keep the lid down.
