Final cover systems are constructed when an area of the landfill has reached its final grade and is no longer accepting waste, or when the entire landfill is closed. This is a critical step in the landfill closure process, as the final cover is designed to manage the environmental impacts of the waste remaining in the landfill. It serves to minimize water infiltration, reduce landfill gas emissions, and limit exposure to potentially hazardous materials that could leach into the surrounding environment.

The construction of these systems is a regulatory requirement and is essential for ensuring long-term stability and environmental protection of the landfill site. By implementing a final cover system at the correct time, landfill operators can ensure that the site is properly contained and that any remaining environmental risks are effectively managed.
