Liner leaks in cooling ponds are typically detected through a combination of regular monitoring and advanced detection methods. One common technique is visual inspection, where workers carefully examine the surface of the liner for any signs of damage, such as tears, punctures, or gaps. For more precise detection, tools like water pressure testing or electronic leak detection systems are used.
These systems can pinpoint small leaks by measuring changes in water levels or using sensors to detect moisture underneath the liner. Once a leak is identified, it is repaired by cleaning the damaged area, removing any debris, and then patching the liner with a matching material, such as a piece of geomembrane. The patch is sealed using heat welding or adhesive bonding to ensure it forms a watertight seal. In some cases, the area around the leak may need to be reinforced to prevent further damage.
