Landfill Construction, Repair, and Closure
While most people see landfills as nothing more than places where waste is discarded, the fact is that these are very complex engineered locations.
Landfill construction normally takes many months, and consists of a variety of stages that must be meticulously planned – sometimes over the course of several years – to meet environmental standards.
Specifically, landfill cell construction consists of excavation and soil removal, liner installation, leachate pipe installation, methane gas collection system installation, monitoring well construction, along with other supporting infrastructure.
Over time, landfill repair is inevitable. One of the most common landfill repairs is to leachate pumping systems or pumping stations, a critical component that keeps built up water in landfills from reaching the municipal water supply. Other repairs to address stormwater management and soil erosion are routinely necessary.
Finally, at the end of a landfill’s serviceable lifetime, it’s not uncommon for closure to occur so that the land can be redeveloped for other purposes. According to regulations, landfill closures must include the installation of a cover system that keeps solid waste below the ground surface, minimizes erosion and infiltration, and allows for vegetation growth.
