BTSL is designed as a Level 4 sanitary landfill based on USEPA standards. Level 4 is the highest standard achievable and ensures maximum protection to the environment.
The base of the landfill phases are compartmentalized into various cells to achieve optimum storm water control to minimize leachate production. The cells are progressively filled until they reach full capacity of 120 million tonnes.
The landfill cells are designed with a multi-layer base liner to prevent any leachate from infiltrating into the ground.
An integrated leachate collection system collects leachate from the liner into a chamber to be conveyed to the leachate treatment plant.
