Highlights
The Yuen Long Barrage Scheme is Hong Kong's first large-scale barrage project and features the largest stormwater pumping station in Asia, comparable to other world-class flood prevention projects. Upon completion, the scheme will have a stormwater pumping capacity of 300 cubic meters per second, equivalent to draining six standard swimming pools of water per minute.
The construction works include the installation of an automatic flood barrier, the establishment of a stormwater pumping station, modifications to the Yuen Long nullah, drainage improvement works, enhancements to flood walls, revitalization of the Yuen Long nullah, and the implementation of a dry weather flow (DWF) interception system.
During the visit, participants will initially gather at Long Ping Station and then be transported by coach to the site office. The visit will begin with an experience-sharing session where the project's works and challenges will be discussed. Following this session, the organizer will conduct a site tour for the attendees.
Safety Requirements
Participants should prepare their own safety gears (including safety shoe, reflective jacket and safety helmet) and hold a valid safety Green Card.
Registration
The number of participants is strictly limited. Priority will be given to members of the AGS (HK). The number of attendees will be limited to 20 and the applications will be accepted on a first-come, first-served basis.

Recap of the Day
On October 26, 2024, AGS organized a technical site visit to the Yuen Long Barrage, with support from the Drainage Services Department, Binnies Hong Kong Limited, and China State Construction Engineering Corporation Ltd. This project marks Hong Kong's first large-scale barrage initiative and features the largest stormwater pumping station in Asia.
Participants gained insights into the necessity of the barrage system for protecting the Yuen Long area from flooding during heavy rainfall seasons. The project plans include the construction of a stormwater pumping capacity of 300 m³ per section upon completion, an automatic flood barrier, a stormwater pumping station, a master control center, and associated electrical and mechanical facilities in the Yuen Long Nullah, as well as modifications to the Nullah and drainage improvement works.
The hosts also discussed the foundation work for the pumping station and master control system, emphasizing the use of socket H piles. They elaborated on the design of socket H piles for tension anchoring and detailed the construction work carried out on-site.
Overall, the visit provided participants with valuable insights into the barrage system and its critical importance.
