Welcome to DSD’s Newsletter No. 1 for Kai Tak River projects. This newsletter provides you with latest progress and relevant information of the projects.
DSD’s Kai Tak River Project Background
The drainage capacity of Kai Tak River is inadequate to meet the current flood protection standard. Flooding incidents have occurred at Choi Hung Road and affected Wong Tai Sin and San Po Kong areas during heavy rainstorms. In order to improve the drainage capacity of the Kai Tak River and to mitigate flooding risk to surrounding areas, Drainage Services Department (DSD) is carrying out improvements works for the upstream and midstream sections of the Kai Tak River.
|Upstream Contract||Midstream Contract|
|Contract||Reconstruction, Improvement and Rehabilitation of Kai Tak River from Wong Tai Sin Police Station to Tung Tau II Estate||Reconstruction and Rehabilitation of Kai Tak River from Tung Kwong Road to Prince Edward Road East|
|Scope of Works||(a) Reconstruction and rehabilitation of a section of Kai Tak River of about 600 metres long from Po Kong Village Road to Tung Kwong Road;
(b) Construction of a box culvert of about 400 m long alongside the Kai Tak River from Wong Tai Sin Police Station to Tung Tai Lane;
(c) Relocation of the affected existing watermains and sewers; and associated works.
|(a) Reconstruction and rehabilitation of a section of Kai Tak River of about 500 metres long from Tung Kwong Road to Prince Edward Road East;
(b) Utilities diversion and ancillary works.
|Approved Project Estimate||About HK$1.6 billion||About HK$1.2 billion|
|Commencement Date||31 October 2011||30 December 2013|
|Completion Date||Mid of 2017||End of 2017|
Interim Measures to Improve Drainage Capacity
To enhance the drainage capacity of Kai Tak River temporarily, some of the public utilities and a large water main located at bottle neck of the Kai Tak River were removed in early 2013. We have also implemented following interim measures to improve the drainage capacity.
Construct more gullies and drainage pipes at suitable locations
Replace existing hoarding with chain link fence at suitable locations
Inspect and cleanse existing gullies along Choi Hung Road regularly
Core holes at planter walls and nullah deck to assist draining of rainwater
Provide sand bags to shops and residential buildings who may be affected by heavy rain
Emergency Operations under Flooding Incidents
During black rainstorms on 30 March and 8 May 2014, floodings occurred at Choi Hung Road adjacent to the Kai Tak River. It is mainly due to the water flow of Kai Tak River increased rapidly in a short duration, exceeding its current drainage capacity. In addition, a substantial amount of rubbish and leaves blocked the roadside gullies, which exaggerated the situation. Our Emergency Control Centre and the Kai Tak River emergency team activated promptly after hoisting of rainstorm signals. Workers cleared the debris blocking roadside gullies to allow the draining of rainwater. They also assisted the Police to remove broken-down vehicles, which resulted in the traffic of Choi Hung Road resuming to normal in short period.
Although drainage capacity of existing Kai Tak River is inadequate to deal with severe rainfalls similar to that occurred on 30 March and 8 May this year, we believed that the aforesaid emergency measures and those completed interim measures had reduced the extent and adverse impact of flooding significantly.
