THIRD CROSS-HARBOUR WATER MAIN COMPLETED

*****

THE LAYING OF A THIRD CROSS-HARBOUR MAIN TO INCREASE THE TRANSFER CAPACITY OF WATER SUPPLY FROM KOWLOON TO HONG KONG ISLAND WAS COMPLETED TODAY (THURSDAY).

THE DIRECTOR OF WATER SUPPLIES, MR TOM TOMLINSON, WHO WAS

AT THE WAN CHAI WATERFRONT WITNESSING THE LOWERING OF THE MAINS INTO THE HARBOUR AFTER JOINTING WITH THE LANDFALL SECTION, DESCRIBED THE OPERATION AS A MAJOR STEP FORWARD IN BOOSTING SUPPLY TO HONG KONG ISLAND.+

THE TWIN 1 000-MM DIAMETER SUBMARINE MAINS, EACH MEASURING 1.4 KILOMETRES AND MADE UP OF 220 PIPE LENGTHS WELDED TOGETHER AND LAID ON THE SEABED FROM TSIM SHA TSUI WERE PULLED ACROSS THE HARBOUR BY A HYDRAULIC WINCH LOCATED AT THE WAN CHAI WATERFRONT. THE WORK COST $40 MILLION.

→THE NEW PIPELINE WILL HAVE A CARRYING CAPACITY OF 180 000 CUBIC METRES PER DAY, MR TOMLINSON SAID.

THE TWO EXISTING CROSS-HARBOUR MAINS FROM KOWLOON - ONE FROM TSIM SHA TSUI TO CENTRAL AND THE OTHER FROM HUNG HOM TO NORTH POINT - HAVE A COMBINED CAPACITY OF 335 000 CUBIC METRES PER DAY.

MR TOMLINSON POINTED OUT THAT THE LAYING OF THE SUBMARINE PIPELINE FORMED PART OF A $100 MILLION PROJECT TO CATER FOR THE INCREASING DEMAND FOR WATER SUPPLY TO HONG KONG ISLAND.

OTHER WORKS BEING CARRIED OUT INVOLVE THE LAYING OF SEVEN KILOMETRES OF LAND MAINS ON BOTH SIDES OF THE HARBOUR AND THE COMPLETE SYSTEM WILL BE AVAILABLE FOR USE EARLY NEXT YEAR.

IN KOWLOON, THE MAINS BEING LAID TO LINK UP WITH THE CROSS- HARBOUR PIPELINE EXTEND FROM BOUNDARY STREET TO TSIM SHA TSUI AND ON HONG KONG ISLAND FROM CHATER ROAD TO WAN CHAI.

THE CONSULTANT ENGINEERS FOR THE PROJECT ARE BINNIE AND PARTNERS (HK), THE CONTRACTOR FOR LAYING THE SUBMARINE MAIN IS MCCONNELL DOWELL CONSTRUCTORS (ASIA) LTD., AND FOR THE LAND SECTION LEIGHTON CONTRACTORS PTY. LTD.
