112. Maintenance of Water Works, Aberdeen. A constant supply of water was maintained throughout the year, the total consumption being 30.10 million gallons. This includes 4.08 million gallons supplied through the water boat station and 5.03 million gallons supplied through the 2" main to Ap Lei Chau. During the year a considerable length of the 5" supply main was taken up, cleaned and relaid, which resulted in a considerable improvement in pressure. Trouble has been experienced with the 2″ steel submarine pipe to Ap Lei Chau, due to junk anchors damaging the protective wrapping and so causing corrosion of the pipe. Spare lengths have been inserted by the Government Diver and enquiries have been forwarded to the Crown Agents with a view to obtaining a type of pipe more suitable for the local conditions.
113. The average consumption throughout the year was 82,000 gallons per day, the details of which are given in Table VIII.
114. Maintenance of Water Works, Repulse Bay.—The total quantity of water supplied during the year amounted to 14.93 million gallons or an average consumption of 41,000 gallons per day against a total supply of 18.06 million gallons and an average consumption of 49,000 gallons per day during 1930.
115. Maintenance of Water Works, Stanley.—The total quantity of water supplied during the year amounted to 9.08 million gallons equivalent to an average daily consumption of 25,000 gallons.
116. Maintenance of Water Works, Deep Water Bay, R.B.L. No. 245. The total quantity of water supplied during the year amounted to 1.35 million gallons equivalent to an average daily consumption of 3,700 gallons.
Total expenditure on Maintenance of Village Supplies $4,839.61
117. Water Account (Meters etc.)—The number of meters examined and repaired during the year was 1,936. A systematic overhaul of all meters is being carried out (but is hindered by a continual shortage of new meters). Twenty-one meters were tested in accordance with Regulation 9 of the Water Works Ordinance 16 of 1903.
118. As a result of the recently completed water works extensions, longer periods of constant supply through the Rider Mains have been possible. This has, however, resulted in a considerable falling off in the demand for meters from the Rider Main Districts.
