121. Pokfulam Road Pumping Station. - This building was completed during the year with the exception of some finishings which cannot be undertaken until the erection of the old engine, which has been transferred from the Bonham Road station, now disused, has been completed. The new station comprises a boiler house adjoining the Pokfulam Road containing ample space for the two Cornish boilers which have been transferred from the old station; a coal bunker, capable of storing about 40 tons of coal, and an engine room, sufficiently large to accommodate a new pumping engine made by Messrs. Tangye & Co. in addition to the old engine (also made by Messrs. Tangye & Co.) which has been converted to drive three-throw pumps. A square chimney, 70 feet high, affords ample draught for the boiler furnaces. Quarters for the Chinese staff are provided in the rear of and overlooking the engine house. An overhead travelling crane has been provided for dealing with loads up to about 5 tons and has already proved of great assistance in erecting the two engines. Both boiler and engine rooms are well lighted by windows during the day and electric light has been installed for use by night.
A road to contain the various mains has been constructed and most of the new lines of mains, joining up with the Peak and High Level mains, have been laid.
The new pumping engine commenced regular work on the 28th July and has proved extremely efficient, both in output of water and also in reducing the shocks upon the delivery mains. The engine is coupled direct to three-throw pumps capable of raising water either to the Peak or to the High Levels of the City, the difference in height of delivery being compensated for in the quantity of water raised.
The principal dimensions of the plant are as follows:—
Cylinders 10.4" 16" 24" 24" and pumps 33" : 6" 24"The old engine was taken down and good progress with its re-erection was made by the end of the year. Further allusion is made to this under "Miscellaneous Water Works".
