A leachate collection system is designed to manage the leachate generated within a landfill to prevent environmental contamination. It typically consists of a series of drains, pipes, and collection ponds. The system collects leachate at the base of the landfill through a network of pipes and channels, which then direct it to a treatment facility. Properly designed collection systems are crucial in minimizing the release of toxic substances into the groundwater and surrounding ecosystems.
