NEW TIPPING AREA FOR REFUSE

AT JUNK BAY ****

THE PUBLIC WORKS DEPARTMENT IS TO SET UP SHORTLY A NEW CONTROLLED TIP FOR THE DISPOSAL OF REFUSE AT JUNK BAY,

THIS WILL BRING THE TOTAL NUMBER OF CONTROLLED TIPS THROUGHOUT THE TERRITORY TO EIGHT.

MR. WONG WAN-MING, CHIEF ENGINEER OF THE P.W.D.'S DEVELOPMENT AND AIRPORT DIVISION, CIVIL ENGINEERING OFFICE, SAID TODAY THAT WORK ON THE FIRST PHASE OF STAGE ONE WOULD BEGIN NEXT MONTH AND TAKE THREE YEARS TO COMPLETE.

HE SAID THAT THE SITE AT JUNK BAY WAS RECOMMENDED BY CONSULTANTS IN THE IR 1974 REPORT ON DISPOSAL OF SOLID WASTE IN HONG KONG AS A MAJOR CONTROLLED TIP TO OVERCOME THE LACK OF SOLID WASTE DISPOSAL SITES WITHIN THE TERRITORY OVER THE NEXT TEN YEARS.

+STAGE ONE OF THE TIPPING SITE COVERS AN AREA OF SOME 32 HECTARES AND PROVIDES A CAPACITY OF SIX MILLION TONNES OF SOLID WASTE, + MR. WONG SAID.

+PHASE ONE OF THIS STAGE FORMS THE INITIAL PART OF DEVELOPMENT OF THE TIP AND COVERS AN AREA OF ABOUT FIVE HECTARES. IT HAS A CAPACITY OF JUST UNDER ONE MILLION TONNES OF SOLID

WASTE AND IS EXPECTED TO BE FILLED IN TWO YEARS.+

THE REMAINING PART OF THE TIP AREA WILL BE DEVELOPED LATER.

MR. WONG SAID THAT AS THE TIP WAS SITUATED ALONG THE FORESHORE, THE LAGOON METHOD OF OPERATING A MARINE SITE WOULD BE ADOPTED TO GUARD AGAINST SEA POLLUTION.

+BEFORE TIPPING OF SOLID WASTES BEGINS, THE PHASE 1 AREA WILL BE ENCLOSED BY AN EARTH BUND PROTECTED ON THE SEAWARD SIDE BY 2-1/2-METRE-THICK OF RUBBLE AGAINST TIDAL WAVE EROSION OF THE TIP,+ HE SAID.

+A NETWORK OF EARTH BUNDS WILL BE CONSTRUCTED, DIVIDING THE POCKET OF ENCLOSED SEA INTO A SERIES OF LAGOONS.

+THESE LAGOONS WILL BE FILLED ONE BY ONE BY THE TIPPING OF SOLID WASTE AND WHEN ABOUT THE CREST OF EARTH BUND IS REACHED, THE SOLID WASTE DEPOSITED WITHIN THE LAGOON WILL BE SEALED ON TOP BY A BLANKETING LAYER OF SOFT EARTH FILLING.

+FURTHER CONTROLLED TIPPING WILL THEN CONTINUE OVER THE FLAT AREA SO FORMED IN A MANNER SIMILAR TO AN INLAND SITE. A RUBBLE MOUND WILL BE CONSTRUCTED LATER TO ENCLOSE THE ENTIRE STAGE 1 OF THE TIP.+
