The Drainage Services Department (DSD) is committed to provide flood protection and sewage collection, treatment and disposal services to enabling sustainable development of Hong Kong.

This report describes a wide spectrum of our environmental performance in 2007, which includes a new section reporting the works under the Clean Air Charter. It also highlights our initiatives in providing sustainable drainage services. On sewage treatment, we have extended our works on effluent reuse and worked with the Environmental Protection Department to deliver the tertiarily treated effluent from a pilot plant in the Shek Wu Hui Sewage Treatment Works to the nearby communities for trial use in toilet flushing. On flood protection, apart from improving existing drainage systems not meeting current flood protection standards and reducing the number of flooding black spots, we have been working with the communities concerned to improve the amenity value of nullahs. The nullah in Lung Chu Street, the Kai Tak nullah, and the Yuen Long Town nullah are projects of this type being implemented at various stages in 2007.

We obtained the ISO 14001 certificate in late 2007 to show our continuous commitment to enhance our drainage services in meeting the escalating demand of the society in an environmentally acceptable manner. Your feedback would help us re-examine the environmental issues from different perspective. Therefore, please share your views with us at enquiry @dsd.gov.hk.
