Fake smoke testing of sewers planned

Staff

Engineering consultant KGS Group, which the town retained in the fall of 2009 to complete an inflow and infiltration investigation study on the sanitary sewer collection system, will be performing more smoke testing today through Friday (Oct. 11-14).
The following sections of the system will be charged with fake smoke during the week:
•Second Street East (Colonization Road East to Minnie Avenue);
•Frenette Avenue (mid-block north of Sixth Street to Kaitlyn Drive);
•Kaitlyn Drive (Frenette Avenue to Erin Crescent);
•Erin Crescent (Kaitlyn Drive to the north/south);
•Baeker Bay;
•Sixth Street East (Russell Bay to Banta Boulevard);
•Lyndy Place South (Lyndy Place North to Colonization Road West);
•First Street West (mid-block west of Holmes Avenue to Keating
Avenue);
•Keating Avenue (First Street West south to mid-block);
•Sixth Street East (Walker Avenue to Portage Avenue);
•Church Street (mid-block west of Crowe Avenue to mid-block east of Crowe Avenue);
•Crowe Avenue (Scott Street to Church Street);
•First Street East (Potage Avenue to Mowat Avenue);
•Biddeson Avenue (Colonization Road West to River Road);
•Williams Avenue (Nelson Street to Church Street);
•Church Street (mid-block east of Williams Avenue to the lift station);
•McKenzie Avenue South (north of Third Street East to the dead end); and
•Victoria Avenue South (between Third and Fourth Street East).
The fake smoke is discharged through a sanitary sewer manhole to determine all the paths where the system is connected to the storm sewer system.
For example, if a home has its roof downspouts tied to the sanitary sewer system, the fake smoke will discharge out through the roof eavestroughs, thus indicating a cross connection between the sanitary sewer system and the storm sewer system.
A bylaw has been in place since 1985 where these types of cross connections are unacceptable, and home owners must take steps at their costs to eliminate these cross connections on their property.
The sections of the sanitary sewer system listed above were selected by the consultant based on infiltration and inflow data collected by KGS.
There is an indication these sections are highly-impacted by infiltration or inflow flows.
The sanitary sewer system infiltration and inflow investigation study has been ongoing since August, 2009.
Four sections of the sewer system were tested with smoke last November.
