Job Site Preparation Checklists :: Sanitary Sewer Smoke Blower Inspection

Below is a list of things which the client needs to confirm and have readily accessible for our testing:

Cost for using the power smoker system includes:

  • my travel time from the office to and from the site
     
  • my operator time to regulate and monitor smoke into the system, monitor the smoke blower in residential areas so the equipment is not tampered with and maintain a safety presence around the manhole
     
  • power smoker, 5.5 horsepower Cherni Smoke Blower Cherne Industries
     
  • oil and gas to operate power smoker

Liquid Smoke (click here to view MSDS) for smoke blower is charged extra based on the amount of liquid smoke used, which is dependant on the length of time it takes to run the smoke through the lines and the time it takes to detect leaks. Typically 2 hours of run time uses 1 gallon of liquid smoke. The fewer the number of house laterals connected to the lines between manholes, the less time to run the smoke. We recommend a smoke test of a minimum 10 to 15 minutes per manhole.

 If you require us to stay the night to save on travel costs, hotel and meals will be charged extra at cost.

Client's responsibility:

  • directions to site
     
  • before smoke testing can take place local police and fire agencies must be notified, as well as any potential residential or industrial connections to the line being tested
     
  • to conduct public notification of smoke testing work (it is recommended that you extend the notification beyond the scope of the study area as the smoke will travel outside the area, see linked sample advanced notification form)
     
  • confined space trained personnel and equipment
     
  • traffic control
     
  • manholes are to be dug up, provide equipment to remove covers and covers removed
     
  • clean soil or material around manhole to be made accessible for smoke blower
     
  • required to provide assistance to install and retrieve smoke blower over manhole
     
  • Municipal Services will be required to reduce flow in the lines if pipe plugs are required to be installed
     
  • client responsible to isolate lines with pipe plugs if required before test - lines plugged before testing can fill up with sewer and have the probability of sewer backup flooding residences; we prefer to conduct the test without plugging up the lines
     
  • once smoke is introduced into the system the clients test crew then checks buildings, roof vents, the street, and other areas that potentially could be a source of extraneous water and records those locations for corrective follow-up;
    approximately 2 kilometres per day can be usually completed based on previous work conducted
