Sewer Vapour Testing in Goulds


The City of St. John’s is currently conducting sanitary sewer vapour testing in Goulds, as part of the 2016 sewer assessment work. This work is currently ongoing and expected to continue until Friday, November 25.
During the testing staff from the Environmental Services Division place a large fan over manholes in the street to blow artificially produced vapor into the sanitary sewer system. Staff walk the street and onto all properties to locate and record locations where the vapour is observed exiting from the system, in order to locate deficiencies and areas of the sewer system that need updating.

Vapor testing is industry standard and is an efficient way to identify problem areas. The vapour looks like smoke but it is not smoke, and fire is not used to create the vapour.
There will not be any service interruptions as a result of the vapour test and although staff are accessing manholes and working on your street, we do not anticipate traffic interruptions or delays during the project. We ask that you be mindful of the work activities in your area at all times.
