Internal Property Assessments and Smoke Testing – Port Dover September 30-October 18 - September 20, 2024

Norfolk County has retained Civica Infrastructure Inc. (Civica) to complete the County Wide Inflow and Infiltration Program. The study’s objectives are to identify sources of stormwater or groundwater entering the sanitary sewer system.

Inflow and infiltration occur when water enters the sanitary sewers through pipe network cracks or other undesired connections such as catch basins or roof downspouts. Rainwater and groundwater can fill the pipes and reduce the capacity of the sanitary pipe network and the wastewater treatment plant. This increases the risk of overloading the pipe network and potential basement flooding.

To identify sources of inflow and infiltration, the County has contracted Civica to conduct sewer smoke testing in neighbourhoods on the southeast side of Port Dover (New Lakeshore Road to Hwy 6 from Woodhouse Avenue to Lakeview Avenue.)

Smoke testing is a safe and easy way to locate sources of inflow and infiltration into the system. It consists of blowing harmless visible vapour into the sewer manholes and pipes and observing where the smoke exits from the system. The smoke is expected to exit primarily out of manholes on the street and the sewer plumbing stack at the top of houses.
