DSD awards Design-Build-and-Operate contract for upgrading San Wai Sewage Treatment Works – Phase 1
27 May 2016
The Drainage Services Department (DSD) today (May 27) signed a “Design-Build-and-Operate” contract with ATAL-Degremont-China Harbour Joint Venture for the Upgrading of San Wai Sewage Treatment Works (STW) – Phase 1.
The contract is worth about $3,142 million. Upon the expected completion of relevant construction works in late 2020, the contractor will undertake the operation, repair and maintenance of the STW for a contractual operation period of 15 years.
Speaking at the contract signing ceremony, the Director of Drainage Services, Mr Edwin Tong, said, “The project comprises the design and construction of sewage treatment facilities with a daily treatment capacity of 200 000 cubic metres to cater for the projected additional sewage flow due to development needs in the Northwest New Territories after 2020. The works will also upgrade the treatment level of the STW to the chemically enhanced primary treatment level with ultraviolet disinfection facilities for reducing pollution loads to the northwestern waters.”
The new STW will adopt innovative sedimentation technology, which is more efficient in sedimentation than conventional clarifiers and requires less space, saving almost 40 per cent of the land that would be otherwise needed.
The project employs the BIM (Building Information Modelling) technology to visualise the plant design and other information with 3D images, facilitating not only the co-ordination and planning of different works and resource utilisation during the construction stage, but also the subsequent operation and management of the STW.
