Programme Highlights
We are thrilled to
invite you to an exclusive site visit to the Community Liaison Centre of Sha Tin Cavern
Project!
To promote sustainable
development, the Drainage Services Department (DSD) has been relocating the Sha
Tin Sewage Treatment Works (STSTW) into caverns since 2014. This
large-scale project, set for completion by 2031, will:
·
Release 28
hectares of land for beneficial use
·
Address landscape
and odour issues
·
Modernize sewage
treatment facilities for efficiency and sustainability
The
visit will include:
·
Briefing session
·
Photo and video
showcase
·
Q&A session
Participants
will:
·
Gain insights into
planning, design, and engineering challenges
·
Learn about
excavation and construction techniques
·
Understand the
project's role in Hong Kong’s sustainable development
·
Explore on-site
construction activities and safety measures
Best Reporter Award
Participants
are invited to write an activity report after the visit and compete to win the
best reporter award, with a prize of $500 for the winner.
This
visit provides a valuable opportunity to engage with industry professionals and
enhance understanding of cavern engineering, sewage treatment, and sustainable
urban planning.

ReportTechnical Visit to Relocation of Sha Tin Sewage Treatment Works
By Mr Marco WONG
The
relocation of the Sha Tin Sewage Treatment Works (STSTW) marks a groundbreaking
milestone in Hong Kong’s infrastructure development. As the largest secondary sewage
treatment works in the city, STSTW currently serves nearly one million people
with a daily treatment capacity of 340,000 cubic metres. The ambitious
relocation project to caverns at Nui Po Shan not only enhances operational
efficiency but also serves as a paradigm shift in wastewater management for
Asia and beyond.
A
key highlight of this project is its transformative land-use strategy. By
relocating STSTW, approximately 28 hectares of prime land will be freed up for
housing and other beneficial developments. This initiative aligns with
sustainable urban planning principles, demonstrating how infrastructure can
coexist with environmental and societal needs. Moreover, the new cavern-based
facility will reduce the overall footprint of the plant by half, making it the
largest sewage treatment works in Asia to be housed underground.
Environmental
considerations are at the forefront of this relocation. One of the major
challenges of sewage treatment is odour control. The cavern setting provides
natural barriers, significantly improving odour containment. In addition, all
odour sources will be enclosed and equipped with state-of-the-art
de-odourisation systems. This innovative approach will enhance the surrounding
environment and set a new benchmark for sewage treatment facilities worldwide.
The
construction methodology also incorporates cutting-edge technology. The main
cavern complex, covering approximately 14 hectares with a total volume of 2.3
million cubic metres, is a feat of modern engineering. To ensure worker safety,
the project has adopted the Smart Site Safety System (4S), which leverages
real-time monitoring and data analytics to mitigate risks effectively. This
proactive approach underscores the commitment to maintaining the highest safety
standards.
The
relocation of STSTW exemplifies a forward-thinking solution that balances urban
development, environmental sustainability, and technological innovation. It not
only enhances Hong Kong’s sewage treatment capabilities but also serves as an
inspiring model for cities worldwide. The visit provided invaluable insights
into how engineering ingenuity can redefine infrastructure for a smarter,
greener future.
