This smoke testing program is part of the City’s objective to alleviate Inflow & Infiltration into the sanitary sewer system to meet Metro-Vancouver’s initiative.
If during the test, smoke does enter the premises, please contact the Mar-Tech Underground Services field crews working in your area; they will help you find the leak and help prevent further incidents of smoke entering the building. The crews can also assist you in extracting any smoke. The crews can be approached outside or by calling at (604) 857-2200. As an alternative, you may call the City’s Sewer Foreman at (778) 846-0633.
As a sewer system ages it is in constant need of inspection and repair. Cracked and broken sewer lines and manholes can allow ground water to enter the sewers system. In additional to groundwater, illegal storm water connections and roof downspouts add rainwater to the sewer system. This additional water volume is called inflow and infiltration. During a rain event this additional water can overburden the sewer system and cause overflows. Disconnecting downspouts and other fixtures that collect storm runoff, found connected to the sanitary sewer system, lessens the chances of pipes being overloaded and causing system problems.
