pipes and enlargement of undersized pipes where inadequate pressures existed.
299. The total of 286,000 feet of new mains varying between 2-inch and 18-inch included:
Hong Kong Island:
(1) Elliot Service Reservoir to Swithfield—18″, 12″ and 10″ diameter mains to replace an 8" main and to improve supply; this met the requirements of the Housing Authority's new housing estate at Cadogan Street;
(2) Tin Hau Temple Road-18″ trunk feed to the new North Point Service Reservoir in conjunction with road works;
(3) North Point-In Tin Chiu Street between King's Road and Kai Yuen Terrace to improve pressures in the area;
(4) Java Road—A 6″ main from Tin Chiu Street for about 700 feet eastward, to supply new development;
(5) Various sizes of mains in the following roads, in conjunction with reconstruction work:
Mainland:
Connaught Road; Des Voeux Road; Robinson Road; Bowen Road; Lockhart Road; Shau Kei Wan Main Road,
(1) Approximately 1,000 feet of 18-inch pipes in Cox's Road to improve the supply in the Observatory Hill area.
(2) Approximately 1,800 feet of 12-inch pipes in Waterloo Road to improve the supply in the Ho Man Tin area.
(3) Approximately 2,000 feet of 18-inch and 15-inch pipes to supply the Kwun Tong Reclamation and Housing Zone area.
(4) Approximately 1,250 feet of 8-inch pipes in Yim Po Fong Street to improve supply to the Mong Kok area.
(5) Approximately 8,000 feet of 8-inch pipes at Tai Po, and
(6) 9,000 feet of 6-inch pipes at Fan Ling to improve supplies.
Service Reservoirs
300. All service reservoirs were cleaned and inspected, and no major repairs were required. Inlet and outlet valves were tested and overhauled where necessary. At the Lai Chi Kok Service Reservoir a 12-inch by-pass was laid to connect the inlet and outlet mains. This enabled a supply to Tsuen Wan to be maintained with water from the Jubilee Reservoir during the period when water supply ceased from Tai Lam Chung due to repairs to the tunnel.
Catchwaters
301. Silt and minor slips were cleared from catchwaters. No major repairs were necessary, but leaks in the invert of Shing Mun Catchwater had to be repaired. A measuring flume has been built and a flow recorder installed in that catchwater.
