Currently, about 5 million tonnes of waste are disposed each year at the three strategic landfills in Hong Kong, including the West New Territories (WENT) Landfill, the South East New Territories (SENT) Landfill and the North East New Territories (NENT) Landfill.
In order to maintain the continuity of landfill capacity for disposal of wastes, the Director of Environmental Protection commissioned a study CE45/99 on “Extension of Existing Landfills and Identification of Potential New Waste Disposal Sites” in 2000. The study (CE45/99) was completed in early 2003 and proposed a Strategic Plan for the development of landfill extensions and new sites for the disposal of solid wastes in the next 50 years.
The WENT Landfill Extension forms an integral part in the Strategic Plan in maintaining the continuity of landfill capacity in the West New Territories . The project is to develop the WENT Landfill Extension (about 200 hectares with capacity of 81Mm3) lying between the existing WENT Landfill and the Black Point Power Station at Nim Wan.
The site is located in Tsang Kok Valley which is a hilly terrain site sparsely vegetated with grass and limited patched of shrubs. The easterly ridge forms a boundary with the existing landfill. The northern part is the CLP Tsang Tsui Ash Lagoons and the former BBC Relay Station. The southern area is bounded by the natural topography, with ridgelines rising southwards from the coastline to meet the major east-west trending ridgeline at about +290mPD. The southern part of the site will also encroach onto the Tsing Shan Firing Range .
