218. Pokfulam Road Pumping Station. The present pumping units at this station consist of three steam-driven pumps which are most uneconomical. It is proposed to replace these steam pumps by three diesel-driven units, but two of the existing steam pumps will be left in situ for use in an emergency. The three diesel-driven pumps have been ordered and delivery started in September 1950. The installation of one diesel pump was completed by the end of March 1951, together with the conversion of one of the disused boilers into a fuel oil storage tank,
219. Peak Pumping Mains. In conjunction with the replacement of the Pokfulam Road pumps the delivery mains are being enlarged. Of these a new 15" diameter pumping main was laid to West Point Filters and work commenced on a new 8" diameter steel main to the 750′ tank. These mains will materially reduce the load on the pumps by replacing the common 8" diameter main which is too small and has reached the end of its useful life. Pipes also arrived for a new 8" diameter pumping main to the Peak to replace an inadequate and very old 5″ diameter main. This will be laid during 1951/52.
220. Stand-by Pumps. To provide against a possible failure of the electric power supply all stations previously solely dependent on electric drive are being provided with an independent stand-by drive. At the two Aberdeen pumping stations, Perkins 6-cylinder diesel engines have been installed. The flexible coupling between the motor and pump was provided with V-belt grooves to enable the belt drive from the diesel engine to be taken direct on to the coupling in the event of failure of the power supply. The diesel engine ordered for Albany was still not delivered by the end of the year.
221. Shing Mun Conduit. This scheme is designed to replace an existing open conduit in a bad state of repair with a 36" diameter steel main. Delivery of the pipes ordered was completed in October 1950 and the pipes were transported direct to Shing Mun. A contract was let for work in connexion with the laying of the pipes. Work started on 5th February 1951 and approximately a quarter of the pipes had been laid by the end of the year.
222. Improvement to Fanling Supply. In connexion with the very large demand for additional water supplies by the many Military installations in the Fanling area and also the development of such civil settlements as Luen Wo Market Town, the implementation of the resources of the inadequate Fanling water supply became a necessity. After giving consideration to various new sources of supply, the harnessing of a large stream (river Jhelum) in the vicinity of Hok Tau Village was decided upon. The gauging operations showed that after withdrawing 200,000 gallons per day to augment the Fanling water supply, the stream still could provide approximately the same amount of water for the irrigational
