Pumping.
156. The amounts of filtered water pumped by the various pumping stations on the distribution system are given in Appendix VII. The total amount pumped to the Peak was 44.94 million gallons, equal to a daily average of 123,000 gallons, and to the high-level districts 255.22 million gallons, equal to a daily average of about 690,000 gallons. In addition, an amount of 324.15 million gallons, equal to a daily average of 888,000 gallons, was pumped for consumption in the city.
157. Unfiltered water was pumped from the Storage Reservoirs by the Tytam Tuk, Aberdeen, and Pokfulam Reservoir Pumping Stations. At Tytam Tuk, 1579.58 million gallons were pumped, which was 11.13 million gallons less than in 1939. At Aberdeen, the upper pump worked 1064 hours and the lower pump for 2190 hours. (These pumps are boosters only.) At Pokfulam Reservoir, 76.17 million gallons were pumped to the Filter Beds.
Details of pumping returns and costs are given in Appendix VII.
Filtration.
158. The total amounts of water filtered at each filtration plant are given in Appendix IV.
159. Consumption.
The total quantity of filtered water supplied amounted to 5,849.86 million gallons, representing an average daily consumption of 16.03 million gallons per day, which included 2,218.24 million gallons from the Mainland. The total consumption was 47.88 million gallons, equal to 0.13 million gallons per day, more than in 1939. Water was supplied from the Mainland throughout the year, the daily average being 6.08 million gallons, which is equal to 37.9% of the Island's average consumption.
160. The average consumption of water per head per day for all purposes was twenty gallons. In arriving at this figure, the population has been estimated at 800,000.
Quality of Water.
