Summit County Sanitary Smoke Testing

Project Description

The Environmental Design Group and C&K Industrial Inc., on behalf of the Summit County Department of Sanitary Sewer Service (DOSSS), will be conducting a smoke testing investigation of the sanitary sewer during the next several months near East Streetsboro street between East Main Street and Hayden Parkway, South Oviatt Street, and a portion of Ravenna Street. See the full map of the smoke testing area here. Testing is expected to begin Tuesday, September 4, 2018.

An important task of the testing will be to locate breaks and defects in the sewer system. The smoke will also reveal sources of where storm and other surface water enter the sewer system.The information gained from this testing will be used to improve the sewer services and may reduce the eventual cost to utility customers.

Homes that will be affected will receive a letter and door hanger prior to the work with instructions. See the map for the general testing area. Workers will be present in the street near the homes and may traverse yards around the homes in that area while inspecting for smoke. Workers will have a copy of the letter and personal identification with them while performing the inspection.

The testing procedure introduces smoke into the underground sewer main while workers monitor above ground for visual indications of smoke. The appearance of smoke above ground can indicate a sewer defect, leak, or clean water connection to the sewer system. During the test, you may see smoke emanating from vent stacks on building roofs, gutter downspouts, storm drain catch basins, or from the ground. Do not be alarmed; this is a normal part of the test. The smoke has no odor, is non-toxic, non-staining, does not create a fire hazard, and will dissipate in a few minutes.

The smoke has no odor, is non-toxic, non-staining, does not
create a fire hazard 
and will dissipate in a few minutes.

Because the plumbing appliances in your house or building are connected to the sanitary sewer system, some smoke may enter your home or place of business if the:
  • Vents connected to your building's sewer pipes 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 buildings are damaged, defective, have plugs missing, or are improperly installed.
To limit the possibility of smoke entering your premises during the testing, please:
  • Fill traps on any unused drains (floor, sink, shower, etc.) by pouring ½ gallon of water into each unused drain.
  • If remodeling or constructing new drain lines, make sure that open lines are temporarily plugged between work sessions.

All residents are 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 also may enter. These can be both unpleasant and dangerous, as well as a health risk to the occupants. Should smoke enter your home or business, please contact a member of the smoke testing crew working in your area or call 330-926-2501.

The crew member will be able to help and check with you as to where the smoke has entered your building. Location, identification, and correction of the source of smoke that enters your building is urgently advised. Your cooperation will be appreciated.
