     The Drainage Services Department (DSD) today (August 25) awarded a $1,358 million contract for the construction of new sludge dewatering facilities at Stonecutters Island Sewage Treatment Works (SCISTW).

     Speaking after the contract signing ceremony, the Assistant Director of Drainage Services (Sewage Services), Mr Shiu Wing-yu, said this is the sixth works contract awarded for the Harbour Area Treatment Scheme (HATS) Stage 2A.  

     "This contract comprises the upgrading of the sludge dewatering and storage facilities and the construction of a new workshop building at the SCISTW.  Raw sludge generated from sewage treatment must be dewatered before receiving final treatment at the future sludge treatment facilities.  In this contract, 14 centrifuges will be installed with a total sludge dewatering capacity of 1,500m3 per hour," he 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.  

     To further improve the water quality of the harbour, HATS Stage 2A will collect the remaining 25% of the sewage generated from northern and southwestern parts of Hong Kong Island. HATS 2A comprises the construction of 21 kilometres of tunnels, and expansion and upgrading of the SCISTW facilities and related preliminary sewage treatment plants on Hong Kong Island.

     HATS Stage 2A is targeted for commissioning at the end of 2014. In view of site constraints, some ancillary works under this contract can only be carried out after the commissioning of the main works in 2014. The whole contract is therefore scheduled for completion in 2016.  The contract will create about 270 jobs in the construction industry.
