The Project

Sai Kung Drainage Improvement 西貢雨水排放改善工程

Over the last 10 years, rapid development in Sai Kung has resulted in a higher surface runoff and the existing drainage systems that have been designed with lower flood protection level are no longer adequate to provide the flood protection standards required for developed areas. This Project purposes to improve the lower sections of the three river channels and aims to relief the potential flooding risk which may cause danger to human life, damage to properties and to a lesser extent nuisance to the public.

The overall environmental acceptability of the Project has been carefully considered and balanced in the EIA Study and the engineering design work. Possible alternatives alignments and construction options have been evaluated to minimise environmental impacts.

The detailed design of the drainage improvements has reflected the potential ecological value of the existing rivers, and natural features of the rivers will be retained wherever possible. Ecologically friendly designed river channels have been applied instead of the conventional concrete bed channel so as to restore and enhance the ecological habitats in the original river channel. Compensatory planting has been incorporated to mitigate the loss of natural riparian vegetation.

Title of Designated Project	Drainage Improvement in Sai Kung (This designated project is hereafter referred to as "the Project")
Nature of Designated Project	To improve the existing drainage systems of Sai Kung by improving existing drainage channels
Location of Designated Project	The parts of the project that are classified as designated project involves drainage improvement works at "Ho Chung Channel" and "Pak Kong River"
Scale and Scope of Designated Project	The proposed work involves the followings: (A). Ho Chung Channel: 1 construction of approximately 300m long trapezoidal channel; 2 construction of approximately 350m long rectangular channel; 3 reprovision of three pedestrian crossing; and 4 reconstruction of existing vehicular crossing and weir. (B). Pak Kong River: 1 repovision of one pedestrian and one vehicular crossing to 3-cell box culverts; and 2 construction of approximately 100m long retaining walls.
