Sustainability Report 2020-21
“Discovery • State of the Art • Drainage Services”
This Sustainability Report summarises our achievements in the past year and enables our stakeholders to have a better understanding of our vision to enhance environment, social and governance aspects 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
Inter-reservoirs Transfer Scheme
Through construction of a water tunnel of about 2.8 kilometres long with 3m diameter connecting Kowloon Byewash Reservoir and Lower Shing Mun Reservoir, the "Inter-reservoirs Transfer Scheme" will lower the possibility of overflow from the former and reduce the flood risk of Lai Chi Kok, Cheung Sha Wan and Shum Shui Po areas. It will also generate an estimated average annual additional fresh water yield of about 3.4 million cubic metres (about 1360 nos. standard swimming pools) to achieve the dual goals of flood prevention and water conservation.
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.
Revitalization of Tsui Ping River
Tsui Ping River, previously named as King Yip Street nullah, is located in the center of Kwun Tong District abuts the Kwun Tong Business Area and residential area. To complement the Energizing Kowloon East Initiative in transforming Kowloon East into another Core Business District for the city, the government put forward the concept of revitalizing King Yip Street Nullah into a unique river with environmental, ecological and landscaping upgrading works. The project comprises the transformation of the existing 1km long nullah alongside King Yip Street, King Yip Lane and Tsui Ping Road into Tsui Ping River with hydraulic capacity, environmental, ecological and landscaping upgrading. To cope with the objective of the revitalization, the project will also beautify the adjacent pedestrian walkways, enhance the connectivity with the pedestrian network and add diversity to the Kwun Tong District.
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.
