The配套渗滤液调节池 project at a certain waste landfill in Longyan City, Fujian Province features a 7,400 cubic meter capacity regulation pond. It is lined with double-layer geomembrane for waterproofing. Integrity testing of the geomembrane was conducted prior to commissioning, using the electric-heat method. One mechanical damage was found, which was repaired through geomembrane extrusion welding and passed retesting.
