Reservoir & Dam Seepage Detection in British Columbia

Seepage through reservoir liners, dam embankments, and dyke structures is a critical infrastructure concern. Undetected seepage can lead to internal erosion (piping), structural instability, and ultimately catastrophic failure. Traditional seepage monitoring relies on visual inspection and downstream flow measurement, which detect problems only after they have progressed significantly. We deploy drone-mounted thermal imaging to survey large reservoir and dam surfaces rapidly, identifying temperature anomalies caused by water migration through the structure. For targeted investigation of suspected seepage zones, we use acoustic methods and, where applicable, tracer gas injection into drain systems. Our drone surveys cover expansive areas that would require days of ground-based inspection in a single flight, providing comprehensive baseline data for ongoing monitoring programs.
