Works proceeded, either in the design stages or under construction, to improve the water supply to the eastern and western areas of Hong Kong, as well as to Pok Fu Lam and Aberdeen in the south of the island. The project for Lamma Island water supply, the new tunnel pipeline system as a further development of the East River Scheme, the supply system for Yuen Long Industrial Estate, and work on improvement of the water supply to Wong Chuk Hang were completed. The laying of the new cross-harbour mains from Kowloon to Hong Kong was well in progress. Works to improve the water supply to Sheung Shui and to Sai Kung continued.
Distribution systems were extended and enlarged to meet urban and rural demands in areas such as Sha Tin, Yuen Long, Tuen Mun, Tsuen Wan, Junk Bay, Fanling and Tai Po. In addition, several new pumping stations were put into service at Mount Parker, So Kon Po, Tong Shui Road, Sai Kung, North Point Ultra High Level and Tai Wo Chuen. Additional pumping equipment was also installed in pumping stations on Cheung Chau and at Tuen Mun, Central waterfront, Kau Wah Keng, Magazine Gap, Telegraph Bay, Shum Wan Shan, Tai O and Beacon Hill.
A network of consumer enquiry centres was being set up at various locations, adding to the existing three centres at Causeway Bay, Mong Kok and Tai Po which have proved very successful. The additional management information to be produced by the existing computer for water billing was still under consideration.
