Wastewater containment systems are tested for leaks using various methods, including visual inspections, leak detection sensors, and other high tech tools. One common approach is the visual inspection of the containment structure and liner for any signs of cracks, tears, or damage. Another method is the use of leak detection technologies, such as electronic sensors or soil probes, which can detect the presence of moisture or changes in moisture levels that may indicate a leak.
Pressure testing involves pressurizing the containment system and monitoring for pressure drops, indicating potential leaks. Tracer tests involve introducing a non-toxic dye or tracer substance into the system and monitoring for its presence outside the containment area. Additionally, geophysical surveys, such as ground-penetrating radar or infrared imaging, can help identify potential areas of leakage.
