Inflow & Infiltration (I&I)


Sanitary Sewer Smoke Testing Program

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.

Rainwater that enters the sanitary sewer system causes two (2) main problems:

  1. The waste water is conveyed to the Annacis Island Waste Water Treatment Plant for treatment before it is discharged to the Fraser River. The City pays for this treatment, so the extra rainwater that enters the sanitary system means that the City will be spending extra tax dollars for its share of treatment and conveyance costs.
  2. Sanitary sewers, pump stations and treatment plants are sized to accommodate only sanitary sewer effluent and are not sized to accommodate extra rainwater that enters the system. These systems may potentially overflow because of this excess volume of water, and may result in property damage or negative impact to the environment. In addition, increased pumping results in premature wear in the pumps and excessive power costs.
