Q 17
The work of overhauling the valves on the mains in the city continued. 257 were repaired on principal mains and ninety-three on sub-mains.
At the end of the year forty-three public stand pipes, 202 pedestal fire hydrants and 666 underground hydrants were in use.
Particulars of main mileage on the Island are given in Table XII.
New services were constructed or old ones altered, improved, repaired or connected to the mains to the number of 12,458 and forty-eight supplies were laid for building purposes.
The number of inspections of services carried out was 10,177. Defective services were found in 1,038 cases, all of which were put in proper repair after the usual notices had been served.
Particulars of the quantity of water supplied by meters are given in Table VI. The amount of filtered water so supplied was 3,438.00 million gallons, 67.8% of the total consumption of filtered water for the year has therefore been accounted for by meters compared with 65.4% in 1986. After making allowance for unmetered supplies given through public stand pipes, washing filters, mains and services, meter slip, fires etc. it is estimated that 73.3% of the total consumption has been accounted for.
A considerable amount of experimental waste detection work was carried out and proposals for the establishment of a permanent waste detection branch were submitted to Government.
Expenditure $244,257.41
63. Village Water Supplies-(a) Shaukiwan and Chai Wan: The supply was subjected to restrictions similar to those in force in the City of Victoria. A constant supply was maintained for 229 days.
The total consumption of filtered water from the Chai Wan Filters was 58.09 million gallons which includes 1.76 million gallons supplied to the boat population and 7.28 million gallons to the barracks at Chai Wan, this is equivalent to an average of 159,000 gallons per day. Details of consumption are given in Table VIII. During the dry season the supply was augmented from the city system.
The supply was treated with 14 cwt. of chloride of lime which is equivalent to an average dose of chlorine of about 0.27 of a part per million.
