124. Miscellaneous Water Works.-The following are the principal items of expenditure under this heading representing in some instances only part of the cost of the works in consequence of their extending over more than one year :-
...
(i.) 5" Main at Aberdeen, (completed in 1912), $853.64
(ii.) Altering alignment of rising mains for the supply of the Hill District, (not completed), $347.00
(iii.) Diversion of main at Wongneichong Village, (completed), $908.41
(iv.) Abolition of syphons in the Pokfulam Conduit and construction of culvert in place of same, (completed), $740.23
(v.) Extension of Fire Hydrants, etc., Kennedy Road, (not completed), $366.61
(vi.) Extensions to Belchers Street main, (not completed), $793.19
(vii.) Alteration to Gauge Basin, Pokfulam Reservoir, (completed), $864.30
(viii.) Channel from Wongneichong Reservoir, $54.60
(ix.) Clearing Pokfulam Conduit near Villa Lucia, $646.16
(x.) Raising Bowen Road Conduit near Tunnel Outlet, $409.94
Item (i). The main referred to was completed and brought into use in 1912 but a balance of $853.64 remained to be paid in 1913. An alteration of the pipe from the Paper Mill supply main to the filter beds was found to be necessary on account of the improved pressure, consequent upon the laying of the new 5" main, resulting in an increase in the consumption of water.
Item (ii). It was not considered expedient to proceed with this work owing to the necessity for keeping in reserve until the arrival of new pipes, which had been indented for in connection with the new Pokfulam Road Pumping Station, such pipes as were in Store. The new pipes arrived at the end of the year and the necessary alterations to the Peak main will be undertaken as early as possible during 1914.
Item (iii). This work was rendered necessary by the laying out of the land to the north and north-west of Wongneichong Village for building purposes, the line and levels of the roadway undergoing considerable alterations.
Item (iv). As Pokfulam Reservoir fills more rapidly than those in the Tytam area, it is important that it should be possible to utilize the water from it to the greatest extent possible, leaving the other reservoirs to fill. The occurrence of syphons at two points on the route of the Pokfulam Conduit resulted in the discharging capacity of the conduit being seriously impaired and the removal of these syphons was therefore undertaken, lengths of conduit contouring the hillside being substituted for them.
