Smoke Testing

Although CCTV video inspection is  an important component of an infiltration inflow survey, smoke testing is a quick way of inspecting both the sewer mainlines and laterals. Smoke travels throughout the system, identifying problems in all connected lines. This type of sewer line testing is becoming more relevant due to being quick, cost effective and proactive.  As a result, it’s a great way to look after assets that are continually aging and deteriorating.

Smoke testing sewer lines is a relatively simple process that consists of blowing non-toxic smoke mixed with large volumes of air into the sewer line. The smoke travels the path of least resistance and quickly shows up at sites that allow surface water inflow. Smoke will identify broken manholes, illegal connections including roof drains, sump pumps and yard drains.
