double leachate collection system
Quick Summary
A double leachate collection system is a crucial component of secure landfills used in waste management. These systems are designed to prevent hazardous waste from contaminating groundwater and the environment.1
In a secure landfill, a double leachate collection system consists of two impermeable liners with a network of perforated pipes placed above each liner. The upper system collects any leachate that forms within the waste, while the lower system acts as a backup to capture any leaks from the primary system. The collected leachate is then pumped to a treatment plant. This dual-layer approach ensures robust containment and monitoring of potentially harmful liquids produced by decomposing waste.12
