in 1950 was further increased during the year by the duplication of the section from Eastern Reservoir to the bottom of Happy Valley. Completion of the enlargement of the main eastward from North Point tank gave some relief to Shaukiwan.
180. Improvements in the Western District comprised enlargement of the outlets from Elliot and West Point Service Reservoirs and the installation of cross connexions between the Albany-Elliot trunk main and the distribution system.
181. The supply to the Wanchai area was improved by the laying of a 15″ main in Queen's Road East, a portion of which involved replacing an existing 10″ main. This work was co-ordinated with the reconstruction of the road by the Roads Office.
182. On the Mainland, the most difficult supply area was Sham Shui Po. To improve the supply to this area, repairs to the Kowloon Balance Tank referred to below were put in hand. Other works included a bye-pass from the Shek Lai Pui trunk mains and the renewal of several sub-mains in the area. Investigations as a result of complaints from consumers showed many back lane pipes to be too small and overloaded. Extensive renewals were undertaken.
183. Filtration. Filters were working to capacity during the summer, but the supply was still inadequate. It was, therefore, decided to increase filtration capacity in order to utilize flood water, and schemes for additional filters at Kowloon and Tytam were included in the major works programme.
184. Automatic chlorine dosing plant was installed in three of the New Territories village supplies at Taipo, Tsun Wan, and Hok Tau.
185. An experiment in the recovery of wash water was made at Eastern Filters using one of the disused slow sand filter beds to settle out the sludge from the discarded wash water.
