of the existing sewerage systems to be overloaded. In particular the sewers of the Wan Chai district of the Island and the Yau Ma Tei district on the Mainland were running under surcharged conditions. To permit further redevelopment in many parts of the urban areas, it will be necessary to enlarge or duplicate the sewerage systems for the accommodation of the additional sewage.
6.02. This overloading of the existing systems was reflected by an increase of 4.75 per cent in the number of chokes which occurred in the sewers during the year, from 11,733 to 12,293.
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) 43,917 99,202 39,383 182,502 Defective drains replaced (length in feet) 8,628 4,693 465 13,786 Connexions provided (Nos.) 641 984 319 1,944 Chokes cleared (Nos.) 5,888 6,192 213 12,293 Sand cleared from culverts and nullahs (cubic yards) 3,524 68,682 9,192 81,398SEWERAGE AND SEWAGE DISPOSAL
6.04. Construction of intercepting sewers was completed for the North Point Sewerage Scheme, commenced for the Central Sewerage Scheme, and continued for Kwun Tong and Kowloon South Schemes.
6.05. Good progress was made on the laying of the submarine sewer outfall off Tong Shui Road. With its completion in October 1962, the North Point intercepting sewers will be brought into use.
6.06. The Imhoff Tank at Deep Water Bay was put into operation and the pollution of this beach was much reduced.
6.07. 6,375 feet of sewers were relaid because of defects or because they were too small for the present population.
STORMWATER DRAINS AND RIVER TRAINING
6.08. Major stormwater culverts were constructed in How Ming Street, Hoi Yuen Street and So Mo Ping, Kwun Tong, and in Kwu Hang Road and Tai Ho Road, Tsuen Wan. The construction of these culverts was necessary to allow reclamation to proceed.
6.09. River training works were undertaken at Tai Wai for the Shing Mun River, at Fanling for the Indus River, and at Yuen Long for the
