Potential uses of an IR camera to detect and quantify lateral connections in sewers

Research output: Contribution to conferenceAbstractScientific

Abstract

Illicit connections are a major reason of the inefficiency of some separate sewers. Despite theirs costs, dye tracing and smoke test methods are common to investigate mis-connections. An infrared camera (FLIR, A35) was used to identify abnormal thermal finger prints (due to lateral connections) along a flume. The illicit connections were simulated by discharging warm or cold water through several types of lateral connections (variation of diameter, intrusion, depth, etc.). Data analysis revealed that the detection of both illicit connections and groundwater infiltration is possible, albeit under certain conditions.
