Relocation of Sha Tin Sewage Treatment Works to Caverns

Commissioned in 1995, Stanley Sewage Treatment Works is the first sewage treatment works built in caverns in Hong Kong. It is a secondary sewage treatment works with design daily sewage treatment capacity of 11,600m³.
Latest cavern construction technology was adopted in the design and construction of this plant at that time. It was housed inside three large caverns, each about 120m long, 15m wide and 17m high together with over 450m of access road, ventilation tunnels and shafts.
Integrating with the Surrounding Community and Environment
Integrating with the surrounding environment, not easily visualised by the public
Live with the nearby community in harmony, not causing any adverse impact
The nearest distances between the ventilation shaft and St. Stephen's College Preparatory School, staff quarters of Correctional Services Department and the residential area are about 200m, 300m and 400m respectively
Examples of cavern sewage treatment works in Hong Kong and the Nordic countries can successfully integrate with the surrounding community and environment. We will not only learn from the successful experience of these examples, but also introduce other enhanced and innovative elements in response to the project situation and residents’ concerns, in order to further improve the overall planning of the relocation proposal.
