Q 36
From the above table it will be seen that an unrestricted 24 hours supply was not turned on during the whole year and that the Rider Mains were closed during 219 days of the year.
Numerous emergency measures to augment the regular supplies were taken and the following are worthy of record:
Source. Period in operation. Quantity obtained in M. G. Daily Quantity M. G. Remarks. Tai Koo Refinery Supply, 2nd February to 17th August. 19.12 0.10 Connection made to Govt. Main at North Point. Lai Chi Kok Water Boat Dock, 21st March to 29th July. 40.00 0.30 Transported to Tanks on Praya by Water Boat. Tsun Wan Stream, 9th June to 29th July. 13.98 0.27 Do. Imported Supplies, ... 8th June to 30th July. 13.44 0.25 From outports and Canton River Delta by W. E. Committee. Total 36.54 0.92 AverageAltogether 21 tanks of a total capacity of 1.05 million gallons were erected on the Praya between Douglas Street and Kennedy Town and on the Praya East Reclamation. Approximately half of the tanks were supplied with water from Lai Chi Kok and Tsun Wan and remainder with imported supplies. Fountains north of Queen's Road were generally closed whilst tank supplies were available.
With a 4 hours per day supply and the above supplies in operation the draw-off from the permanent supply fell below 3 million gallons per day.
In addition to the above supplies several streams were diverted into the Bowen Road and Pokfulum Conduits and yielded approximately 100 million gallons after the rains had set in. A further 45 million gallons was likewise obtained by the construction of a channel approximately 4,500 feet in length at Tytam Tuk. This channel, which was completed on 22nd July, diverts the run off from 150 acres into Tytam Tuk Reservoir and as that reservoir did not overflow during the year the full benefit of these additional supplies was obtained. This channel will be available until superseded by the permanent Tytam Tuk East Catchwater.
