135. Miscellaneous Water Works.-The following are the principal items of expenditure under this head, representing in some instances only part of the cost of the works in consequence of their extending over more than one year :-
(i.) Altering alignment of rising mains for the supply of the Hill District, (completed), $750.66
(ii) Conversion of old compound pumping engine into triple expansion engine, (completed), $855.02
(iii) Constructing ash bin at Pokfulam Road Pumping Station, (completed), $807.30
(iv.) Cleaning and repairing No. 1 Intake, Shaukiwan Water Works, (completed), $399.97
(v.) Laying pipe-line near Sywan Gap Filter Beds to render available the water from an additional stream-course, $787.86
(vi.) Laying new 4" main in Caroline Road, $1,217.82
1915 Estimates, $6,000.00
1915 Expenditure, $4,843.88*
Item (i). This work was described in last year's Report (vide page 73).
Item (ii). This work was also described in last year's Report (vide page 73). The addition of the third cylinder has effected a great improvement in the working of the pumps and has entirely overcome the defect formerly existing.
Item (iii). Hitherto, it has been possible to dispose of the clinker and ashes from the boilers of the Pokfulam Road Pumping Station by depositing them on Crown land adjacent to the Station, but, as the available space has now been fully utilized, it became necessary to make other arrangements. A large bin, with a capacity of 85 cubic yards, has accordingly been constructed on the north side of Pokfulam Road in close proximity to the Station. The bin is constructed entirely of concrete and, as it is below the level of the road, concrete gangways have been provided, across which the ashes, &c., can be wheeled or carried and tipped in any vacant space that may be available. Facilities are provided for emptying the bin which is divided into two sections by a partition wall. The bin will be emptied periodically, the contents being conveyed to junks and deposited at sea.
Item (iv). The completion of the Shaukiwan Water Works Extension (vide paragraph 118 of last year's Report) has rendered it possible to clean and repair the intakes constructed in 1896. The whole of the filtering material was washed and the intake was thoroughly repaired.
* A sum of $25.25, expended in connection with Kowloon Water Works, was inadvertently charged to this Vote.
