Contract awarded for Harbour Area Treatment Scheme (HATS) Stage 2A
20 January 2011
The Drainage Services Department (DSD) today (January 20) awarded a $625 million contract for upgrading the preliminary treatment works at North Point, Wan Chai East and Central.
Speaking after the contract signing ceremony, the Director of Drainage Services, Mr CHAN Chi-chiu said this is the eighth major works contract awarded under the Harbour Area Treatment Scheme (HATS) Stage 2A.
“This contract comprises the upgrading of three preliminary treatment works (PTWs) at North Point, Wan Chai East and Central. The PTWs provide preliminary treatment to the sewage before the sewage is conveyed via the deep sewage tunnels to the Stonecutters Island Sewage Treatment Works (SCISTW) for further treatment. The major works of this contract include upgrading the inlet sewage pumps, the fine screen systems and the grit removal systems as well as the enhancement of the deodorisation systems and landscaping areas of the PTWs.” Mr Chan said.
HATS is a major sewerage infrastructure project in Hong Kong to improve the water quality of Victoria Harbour. The commissioning of HATS Stage 1 in late 2001 has provided proper treatment to about 75% of the sewage discharged into Victoria Harbour, and has significantly improved the water quality in the eastern and central parts of the harbour. HATS Stage 2A will collect the remaining 25% of the sewage generated from the northern and southwestern parts of Hong Kong Island, and involves the construction of approximately 21 kilometres of sewage tunnels, and expansion and upgrading of the SCISTW facilities and related PTWs on Hong Kong Island.
The contract is scheduled for completion at the end of 2014.
