Smoke Testing
Beginning Monday, City crews will be conducting sanitary storm sewer testing in the Harewood neighbourhood (between Bruce Ave, Seventh St, Sixth St and Park Ave) using smoke to detect if anything other than wastewater is entering the sewer system. Smoke testing is an efficient and cost-effective way to inspect the sewer system and works by having crews position a blower at a manhole and blowing smoke down into it. If there are any openings, some of the smoke will escape and be visible from holes in the ground or vent stacks on houses. Please note, the smoke is not toxic and is harmless to humans, pets, food and materials.
