The landfill covers a total area of 350 hectares and has a capacity of 28 million m 3 when filled to the perimeter bund level with permanent capping. The bund is lined with impermeable membrane and a layer of marine clay to ensure that the water collected in the landfill due to rainfall and the filing of ash is contained within the area and treated at a wastewater treatment plant.
