Smoke Testing of the Sanitary Sewer System


For Immediate Release:      

 

Smoke Testing of the Sanitary Sewer System
During the First Three Weeks of September
August 29, 2019
3:30pm


Smithfield, NC -- Please be advised that the Johnston County Department of Public Utilities will be conducting smoke testing of the sanitary sewer system in the I-40/NC 42 Interchange area and the Cleveland Road/N Shiloh Rd/S Shiloh Road Intersection area during the first three weeks of September.  The testing areas are identified on the attached map.

The work will involve the opening and entering of manholes in the streets and public utility easements.  The County will use a non-toxic smoke designed specifically for this type of testing.  The smoke leaves no residuals or stains, and has no effect on plant or animal life.  The smoke has a distinctive, but not unpleasant, odor.  In areas of adequate ventilation, visible smoke and odor last only a few minutes. 

This testing will identify potential sources or areas of surface water or stormwater infiltration into the County’s wastewater collection system.  The County will use this information to make necessary corrective repairs, prevent infiltration into the wastewater collection system and improve sewer services in the area.    

Since some plumbing appliances in your house or building are connected to the sanitary sewer system, smoke could enter your home or place of business under the following circumstances:

  • Vents connected to your building’s sewer piping are inadequate, defective or improperly installed
  • Traps under sinks, tubs, basins, showers and other drains are dry, defective, improperly installed or missing
  • Pipes, connections and seals of the wastewater drain system in and under your building are damaged, defective have plugs missing or are improperly installed

Please be advised that if traces of this smoke or its odor enter your house or building, it is an indication that gases and odors from the sewer may also enter.  If smoke enters your home or business, please contact the Johnston County Department of Public Utilities at 919-209-8333. 

We sincerely appreciate your cooperation and apologize for any inconvenience.
