BELLEVILLE, IL-- The city of Bellville Illinois will begin smoke testing of sanitary sewers on Monday, 21st of February and will continue for about a month. The smoke will not enter your home if your plumbing is good and water traps intended to keep out sewer gases contain water.

The city will be opening manholes and forcing smoke into the sewer lines in a couple of sections of east Belleville to see where it comes out. The testing identifies defects in the sewer lines, including any fresh water drainage still getting into the system.
