Q 16
The total quantity of filtered water supplied during the year amounted to 5,056.67 million gallons (which includes 1,559.62 million gallons from the Mainland) and 65.73 million gallons unfiltered, making a grand total of 5,122.40 million gallons or 544.85 million gallons more than during 1936.
The total quantity of water pumped for consumption in the High Level District of the City was 189.79 million gallons, equivalent to an average daily consumption of about 520,000 gallons, whilst 69.18 million gallons were pumped to the Peak District giving an average daily consumption of 190,000 gallons.
The turbines and pumping plant at Bowen Road worked satisfactorily and delivered an average daily supply of 114,000 gallons to the 650 feet level Service Reservoir in the High Level District.
The turbines and pumps at the Eastern Filters worked satisfactorily. A daily average of about 108,000 gallons was delivered to the Jardine's Lookout and Middle Gap Service Reservoirs in the High Level Districts.
Apart from some trouble with the motors due to vibration, the electrically driven pumps at Middle Gap worked satisfactorily. A daily average of 35,000 gallons was delivered to Mount Cameron Service Reservoir in the Peak District.
Tabulated statements containing particulars of the quantities of water pumped to the High Level District of the City and to the Peak District will be found in Table VII. All pumping units and station buildings have been kept in good order.
The average consumption of filtered water per head per day for all purposes throughout the year was about 31.2 gallons. In arriving at this figure, the population has been estimated at 445,000. Details of consumption are given in Tables V and VI.
945 tap samples of filtered water on the island were examined by the Government Bacteriologist with the following results:
833 showed B.C.C. absent in 50 C.C.
(88.1%)
82 others were above standard.
(8.7%)
30 were below standard.
(3.2%)
The analyses by the Government Analyst showed that the water was of good quality throughout the year. The city supply was treated with 10.6 tons of liquid chlorine and 2.4 tons of chloride of lime, which is equivalent to an average admixture of about 0.575 of a part per million.
