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
