District Energy & Heating Pipe Leak Detection in Surrey, BC

District energy systems distribute heating and cooling through buried networks of insulated pipes carrying hot water, chilled water, or steam. A leak in these systems is particularly problematic because the heated water accelerates ground erosion and the high-temperature flow can create dangerous surface conditions. Moreover, the water in district energy systems is chemically treated with corrosion inhibitors and antifreeze additives, making leaks an environmental concern. Detecting leaks in district energy piping requires specialized methods because the pipe insulation dampens acoustic signals and the continuous flow conditions mask leak sounds. We use a combination of tracer gas injection, thermal imaging, and acoustic correlation adapted for the insulated pipe environment to locate district energy loop leaks precisely.
