Sustainability Report 2018-19
This Sustainability Report summarises our achievements in the past year and enables our stakeholders to have a better understanding of our vision and commitment to sustainable development.
Sewerage and Flood Protection 1841 – 2018
The year 2019 marked the 30th anniversary of DSD. This Chinese monograph was published to earmark this historical moment. Apart from translating parts of our 20th anniversary monograph, the “Sewerage and Flood Protection – Drainage Services 1841-2008”, into Chinese, we have also highlighted the advancement in drainage services during the 10 years from 2009 to 2018, thereby imprinting the development history on Hong Kong’s drainage services in the past hundred year and more.
Going The Extra Miles
The year 2014-15 marked the 25th anniversary of DSD, we published this monograph to look back on the endeavours and achievements of DSD in the provision of stormwater drainage and sewage treatment services.
Sewerage and Flood Protection
This book traces the major milestones in the history of Hong Kong’s drainage services and outlines our views on sustainable development to meet growing needs in the future.
Fragrant Again Letters to Victoria Harbour
Victoria Harbour is a precious natural asset and an integral part of Hong Kong’s identity. Yet once, not long ago, our treasured harbour was polluted. Our beaches were closed, the Cross Harbour Race suspended and marine life impaired. “Fragrant Again Letters to Victoria Harbour” tells the story of how the Harbour Area Treatment Scheme cleaned up our harbour and restored its beauty, fragrance and vitality.
This book hopes to shed light on these hidden labyrinths that are keeping Hong Kong safe. In relating their story, the DSD wishes to share with readers both the challenges and hard-won successes that shaped these notable projects.
DSD's Iconic projects
Kai Tak River Improvement Works (Wong Tai Sin Section)
Kai Tak River, previously named as Kai Tak Nullah, is one of the major drainage channels in East Kowloon with a total length of about 2.4 kilometre (km) long. Due to urbanisation and extreme weather, drainage capacity of Kai Tak Nullah in the past could not meet the current flood protection standard. Therefore, the Government suggested to carry out drainage improvement works. Through public engagement exercise before commencement of works, design principles for the improvement works have been established: according high priority to increase drainage capacity, minimising river decking and revitalising as a green river.
Upon completion of works, the drainage capacity of Kai Tak River can attain the current design standard, so as to mitigate flooding risk along Choi Hung Road.
Expansion of Sha Tau Kok Sewage Treatment Works
In order to cope with the continuing development needs in Sha Tau Kok area, the Drainage Services Department is carrying out expansion works for the existing Sha Tau Kok Sewage Treatment Works (STKSTW), with an aim to increasing its treatment capacity.
The works includes provision of temporary sewage treatment facilities to maintain sewage treatment services during reconstruction of existing STKSTW, construction of a longer and larger submarine outfall to provide sufficient capacity for discharging the increased treated effluent, and laying of sewers in Sha Tau Kok Town and Tong To. The works was commenced in 2018 for completion in 2024.
Happy Valley Underground Stormwater Storage Scheme
Happy Valley in Hong Kong is a low-lying hinterland at the downstream of a hilly terrain. During heavy rainstorms, runoff from the vast uphill catchment posed flood risk to Happy Valley and its adjoining coastal districts. The public lives were seriously affected.
The Happy Valley Underground Stormwater Storage Scheme innovatively enhances the flood protection level of the city, successfully resolves the flooding problems in Happy Valley and Wan Chai districts. The adoption of smart and automatic movable weirs, water harvesting system and green building designs has created a more resilient and adaptable drainage system that blends harmoniously with the environment.
Relocation of Sha Tin Sewage Treatment Works to Caverns
Releasing of about 28 hectare of land after relocating the existing Sha Tin Sewage Treatment Works (STSTW) to caverns brings multifold benefits to the communities of Sha Tin and Ma On Shan Districts as a whole. On one hand, the environment of the existing STSTW site and its surroundings will be greatly improved. Comparing to the existing open-plant arrangement, the odour management of the proposed relocated STSTW in caverns, with caverns as natural barrier, can be efficiently enhanced so as to minimise the odour impact on the surrounding communities. On the other hand, developing the vacated site for residential and other beneficial uses will benefit the community by meeting the public’s needs.
Stage 1 Works including site preparation and access tunnel construction commenced in February 2019 and targeted for completion in 2022 Q4. The remaining construction works will be implemented in stages. The total construction period of the project is estimated to be about 13 years.
