The Drainage Services Department (DSD) announced today that the deadline was being extended in response to requests from interested tenderers.

The works include construction of a drainage tunnel approximately 3.6km long and about 5m in diameter from Shau Kei Wan and Chai Wan to Pak Sha Wan; construction of seven intakes and an outfall; and ancillary works.

Work is scheduled to commence in August 2026 and will take about 46 months to complete.

The DSD invited tenders for the contract on February 6. The tender period was originally scheduled to expire at noon on April 17.

The extension of the tender period was gazetted today. Details of the tender notice are available on the DSD website.

The DSD has commissioned Binnies Hong Kong Ltd to design and supervise the works.
