1. Scope of the Project
The scope of the project included:
- Revitalization of the existing King Yip Street Nullah, comprising resurfacing of the channel, installation of a smart water gate, provision of water-friendly features, provision of a water supplement system (including modification of two underground stormwater storage tanks near Anderson Road and On Sau Road and provision of a seawater circulation system), installation of three dry weather flow interceptors, provision of a smart surveillance and weather forecast system, riverside lighting, and in-stream plantation, etc.;
- Dredging at the existing channel for about 800 metres in length and reconstruction/strengthening of existing nullah structures for about 740 metres in length;
- Construction of riverside walkways, six cross-river walkways and six landscaped decks; and
- Modification of an existing footbridge across Lei Yue Mun Road.
2. Objectives of the Project
|
Revitalizing the River To revitalize the river channel through various environmental, ecological and landscape upgrading works, so as to provide a green riverine corridor and improve living environment for the community. |
Enhancing Pedestrian Environment & Connectivity To improve riverside walkways and provide cross-river footbridges and landscaped decks, in order to enhance the walkability and connectivity of the river with the surroundings with reference to the sustainable development concept of a “walkable city”. |
|
Creating Vibrant Riverside Public Spaces To create a green riverine corridor with water scenery and amenity for the community. This coupled with the adjacent Tsui Ping River Garden and other amenity and recreational spaces in the vicinity offers synergy and adds diversity to the Kwun Tong District. |
Reducing Flood Risk To enhance the hydraulic capacity of the river which served a catchment area of approximately 520 hectares that covered Sau Mau Ping, Kwun Tong and Lam Tin. The revitalized river is capable of carrying a flood discharge of over 150m3/s. At this flow rate, it takes only 17 seconds to fill up an Olympic standard swimming pool. |

4. Project Challenges
The carrying out of works within the live nullah, which is the major drainage channel of Kowloon East, was very challenging. Coupled with the COVID-19 pandemic occurred during the construction period, the major challenges of the project included:
- Safety risk for the workers working within a live nullah
- Interruption in global supply chain of construction materials due to COVID-19 pandemic
- Ingress of tidal water from Victoria Harbour
- Sensitive receivers of ground disturbance including adjacent buildings and highway structures
In this project website, we demonstrate how the project team utilized various innovative engineering solutions and construction methods in order to achieve the successful completion of the project in terms of cost, time, quality, safety and environmental aspects.
