HBPW Smoke Testing

Throughout the next several weeks the Hannibal Board of Public Works will be performing Smoke Test inspections of the sanitary sewer system.  Smoke Testing is performed periodically throughout the year to help identify areas where unauthorized water is entering the sanitary sewer system.  Unauthorized water can cause an unnecessary load on the Wastewater Treatment Plant and could potentially cause sanitary sewer overflows (SSO).  The information gained form this study will help to improve your sewer services. 

During the testing, the contractor inspection crews will be accessing manholes in order to Smoke Test sewer pipes and locate defects in the sewer system.  Smoke is forced into the sewer lines where it will identify broken manholes, cross connections, and cracked mains.  The smoke vapor blown into the manholes and sewers is NON-TOXIC, HARMLESS AND CREATES NO FIRE HAZARD.  This kind of smoke leaves no residuals or stains and has no effects on plants or animals. 

To help ensure smoke does not enter your homes or business through the sewer connection, please pour 1 quart of water into each sink and floor drain to fill the trap.  Please do not close the stopper or drain, as water needs to enter the drain to fill the trap.  If smoke does enter your home or business, it is generally the result of faulty or damaged plumping connections.  Please move outside and alert the contractor staff on the street or call the number at the bottom for immediate assistance. 

SCADA After-Hours:  (573) 221-0955

We anticipate the smoke testing will require a few days in your neighborhood, but the test for your specific sewer will take approximately 30 minutes.  A few days before the smoke test is performed in your neighborhood you will be notified via door-hanger with additional instructions.  At no time will field staff need to enter your business or residence. 

Check back weekly for up-to-date testing locations. All testing will begin at 8:00am each business day.
