6.01. To cope with the expanding needs of the Colony 31.6 miles of new stormwater drains and 20.3 miles of new sewers were added to the drainage systems.
6.02. The increase both in the population and the daily consumption of water has caused the sewerage system in the heavily built up areas to be overloaded. At the year's end an engineering team was being formed to examine the position and devise the most economical method of overcoming the problem.
6.03. The following table shows the works carried out during the year:
Island Kowloon & New Kowloon New Territories Total New drains laid (length in feet) 49,951 167,947 56,538 274,436 Defective drains replaced (length in feet) 7,172 2,893 1,002 11,067 Connections provided (Nos.) 801 560 411 1,772 Chokes cleared (Nos.) 7,083 6,947 244 14,274 Sand cleared from culverts and nullahs (cubic yards) 6,424 109,325 8,409 124,158SEWERAGE AND SEWAGE DISPOSAL
6.04. Construction of the screening plant at Tsim Sha Tsui for the Kowloon South Sewerage Scheme was commenced, and reclamation of the site for the screening plant by the Kai Tak runway, in connexion with the Kowloon East Sewerage Scheme, was completed. With the completion of these two screening plants, most of the sewage from Kowloon and New Kowloon will be screened before being discharged into the harbour.
6.05. Construction of intercepting sewers was also commenced in Kwai Chung, New Territories: the intercepting sewer in Connaught Road was nearing completion; the Kwun Tong intercepting sewer was extended along Choi Hung Road to Shatin Pass Road to receive the sewage from the Tsz Wan Shan Resettlement Estate; and work on the intercepting sewer along Stanley Main Road and the Imhoff tank was put in hand.
