DRAINAGE

All the urban areas and the newly-developing townships now have water-borne sewerage systems although, in a few areas, there are buildings which are not yet connected to the sewers. Progress on the programme of works, begun a few years ago, to duplicate and replace existing sewers in older areas of the system which are now of inadequate capacity and to construct large intercepting sewers connecting the present outfalls to suitable submarine out- falls continued.

ין

When the programme is completed, all sewage, after preliminary treatment, will wherever possible be discharged through sub- marine outfalls into the main tidal currents around the Colony. In this connection an extensive marine survey of the waters of Tolo Harbour, Victoria Harbour and the associated tidal waters past Tsuen Wan and Castle Peak was begun early in 1969 and continued into 1970. Work commenced on the dredging of the sea bed in Victoria Harbour for two new submarine outfalls, one to serve Wan Chai West and the other to serve Sham Shui Po.

Sewerage systems are also being constructed in the new towns now being developed in the New Territories. Consulting Engineers were appointed to design, construct and study the operation of a pilot sewage treatment plant at Shek Wu Hui. In addition to improving the sanitary conditions of the area this project will provide information on which to base designs of future treat- ment works.

Work continued on the construction of stormwater culverts in conjunction with the Wan Chai reclamation project, and several culverts were constructed in the Aberdeen area. In order to alleviate dangers from landslides, the stormwater drainage serving village areas in Shau Kei Wan is being improved. River training works were in hand at Sha Tin and started on part of the Tung Chung River on Lantau Island as flood control measures; and at Tsuen Wan and Yuen Long in the New Territories extensive sewerage and stormwater drainage systems are being laid.
