The purpose of this smoke testing is to verify the results of prior smoke testing, when smoke exited from several storm inlets in the roadway. This indicates there could be a cross connection between the storm sewer and sanitary sewer in this area, and BCWSA would need to locate this defect and repair it.

During the smoke test, the sanitary sewer pipe in the roadway will be filled with smoke that may exit through the vent stack located on the roof of your home or building.  As long as your home or building is plumbed correctly, the smoke will stay in the pipe.  If you do find smoke in your home, note the location and report it immediately to the personnel performing the test in the area of your property.  Any pipe that leaks smoke into the home can also leak dangerous sewer gases such as methane and hydrogen sulfide and should be repaired immediately.  The smoke is relatively safe, but exposure to it should be limited as it can cause nasal and respiratory irritation.

Any smoke irritation will be temporary and should quickly disappear when exposure has ceased. Persons with health and respiratory ailments should not be indoors during the test.  House pets will react in a manner similar to a prudent person and leave a smoky area.  If an exit is not available or the animal is in a cage, then the pet should be provided with proper ventilation.

To minimize the chance of smoke entering your home, please pour water into ALL drains, including floordrains, and verify that any washing machines or dishwashers have been operated within a few days prior to the date of the test.  If you have any questions or concerns before the date of the test, please feel free to contact Mark Yoder, Carroll Engineering, at (215) 343-5700, extension 505.
