This week’s #TimeLapseTuesday shows 1.4-million cubic yards of excavation and 20-acres of liner system geosynthetic clay liner overlain by a 60-millimeter HDPE geomembrane. The geocomposite leachate drainage layer is overlain by two feet of protective soil cover. Automated leachate collection system at each sump, the lowest area of each cell, conveys leachate through the force main system to the evaporation pond. Liner evaluation reports were approved by TCEQ and the City of Lubbock is currently placing waste in Cell 5.
