EXTENSION OF TAI PO SEWAGE WORKS

*****

CONSTRUCTION OF THE SECOND STAGE OF THE SEWAGE TREATMENT WORKS AT TAI PO INDUSTRIAL ESTATE, NEAR SHUEN WAN, WILL BEGIN LATER THIS YEAR.

TENDERS FOR THE WORK, FORMING PART OF A COMPREHENSIVE SEWAGE TREATMENT SCHEME FOR TAI PO, ARE BEING INVITED BY THE CIVIL ENGINEERING OFFICE OF THE PUBLIC WORKS DEPARTMENT.

TOGETHER WITH THE WORKS ALREADY COMPLETED UNDER STAGE ONE, THIS EXTENSION WILL PROVIDE FULL SEWAGE TREATMENT FACILITIES TO SERVE THE FIRST TWO STAGES OF DEVELOPMENT OF THE INDUSTRIAL ESTATE AND THE INITIAL DEVELOPMENT OF THE NEW TOWN.

MR K.Y. TSANG, ACTING CHIEF ENGINEER OF THE PWD DRAINAGE DIVISION EXPLAINED THAT SEWAGE PURIFICATION WOULD BE BY WAY OF PRELIMINARY TREATMENT FOR REMOVAL OF GRIT AND COARSE SOLID PARTICLES IN THE SEWAGE.

THE NEXT PROCESS WOULD BE PRIMARY SEDIMENTATION FOR THE REMOVAL OF SUSPENDED SOLIDS, AND BIOLOGICAL REDUCTION OF ORGANIC MATTERS UTILISING THE DIFFUSED AIR ACTIVATED SLUDGE PROCESS.

+ THE FINAL TREATED EFFLUENT WILL BE DISCHARGED INTO TOLD HARBOUR AND WILL NOT HAVE ANY DETRIMENTAL EFFECTS ON RECEIVING WATERS,+ HE SAID.

WORK IS EXPECTED TO START IN SEPTEMBER AND WILL TAKE ABOUT 30 MONTHS TO COMPLETE.

IT WILL INCLUDE THE CONSTRUCTION OF PUMPING STATIONS, SCREEN CHAMBERS, GRIT CHANNELS, PRIMARY AND FINAL SETTLING TANKS, AERATION TANKS, AND ANCILLARY ROAD AND DRAINAGE WORKS.

THE SCHEME IS FINANCED JOINTLY BY THE GOVERNMENT AND THE HONG KONG INDUSTRIAL ESTATES CORPORATION.

THE WORKS HAVE BEEN DESIGNED AND CONSTRUCTION WILL BE SUPERVISED BY THE DRAINAGE WORKS DIVISION OF THE CIVIL ENGINEERING OFFICE ON BEHALF OF THE PWD TAI PO AND FANLING NEW TOWN DEVELOPMENT OFFICE AND THE HONG KONG INDUSTRIAL ESTATES CORPORATION.
