Charles County, MD — If you see smoke rising out of the sewers in Charles County, don’t be alarmed. It’s all part of a planned test.  Charles County hopes to help prevent flooding and save money on its sewer maintenance costs by locating all of the storm water services connected to its sanitary sewer system.

The county has hired Flow Assessment Services to perform a study of the county’s sewer system, starting on Monday, Sept.30.

Connections such as catch basins, roof drains, area drains, broken sewer pipes, and open pipe joints will be located through a method called smoke testing.

The testing is performed on sewer manholes that are typically located in the streets or near your residence. Non-toxic and non-staining white smoke is inserted into the sanitary sewer system by means of a smoke generating device. During the test, it is normal to observe smoke emitting from the manhole covers on the street, vent pipes located on the homes, and local business establishments. 

It’s unlikely, but possible that some smoke might creep into your home.

Homes and businesses will receive fliers when testing will be performed within 24 to 72 hours. Heavy rain or weekends could possibly shift the testing beyond the 72-hour time frame. It is not necessary for you to be home while the testing is being performed.

This study will conclude after all sewer systems in the Indian Head Manor and Piney Branch area have been tested.
