Inverted Pyramid Design

The landfill cell was constructed as an inverted pyramid, starting with a 14,000 square meter base. This inverted pyramid design, coupled with systematic layering, allows for greater holding capacity and a longer lifespan. To protect the land, the cell uses a multi-lining system that overlays a layer of gravel, sand, and clay, topped by a specialized liner. The cell has pre-installed gas vents to facilitate the safe release of accumulated gasses, and a pre-installed pipe system underneath the active cell to convey the leachate or waste fluid to the waste water treatment facility.
