Programme Highlights

The Drainage Services Department (DSD) is conducting a feasibility study on relocation of the Sha Tin Sewage Treatment Works (STSTW) into caverns with a view to releasing the existing site of about 28 hectares for housing and other beneficial uses.  STSTW is the largest secondary sewage treatment works in Hong Kong with a designed treatment capacity of 340,000 cu.m/day.  DSD engaged AECOM as the consultants for the feasibility study.


This is a joint presentation by DSD and AECOM.  The talk will introduce the work of the feasibility study and the latest progress.  Furthermore, the speakers will present the local and overseas experience on cavern sewage treatment works, selection of the relocation site, and the results of preliminary technical assessments on odour, traffic and blasting vibrations generated from the project.  Lastly, the speakers will also share their experience in public engagement conducted throughout the feasibility study.
