early August resulted in all the Colony's reservoirs overflowing on the 12th August with the exception of the small Wong Nei Chong Reservoir. Plover Cove Reservoir overflowed for the first time since it was brought into operation in October 1967. However from mid August onwards rainfall was below average and at the beginning of the dry season the total storage in the older reservoirs was only 11,614 million gallons (69.2% of capacity) although Plover Cove Reservoir was 97% full with 36,116 million gallons.
10.09. The 24-hour daily supply which had been generally maintained since 1st October, 1967 was continued throughout the year. Average daily consumption was 158 million gallons and a peak daily demand of 193.6 million gallons was recorded on 22nd September, 1969. The annual consumption showed a 12% increase over last year. To meet the high demand, particularly at the beginning of the winter when the storage in the older reservoirs was low compared with that of Plover Cove Reservoir, it was necessary to provide additional temporary pumping capacity at the River Indus and Sha Tin Stations. These, combined with the installation of new pumps at Tai Po Tau, enabled the quantity of water drawn from Plover Cove Reservoir into supply to be raised from below 40 million gallons a day in September to over 80 million gallons a day in March. Changes in the distribution arrangements were also effected and by the end of the year nearly 60% of the Colony's demand was being met from Plover Cove Reservoir.
10.10. Some damage was caused to installations on Lantau during heavy rainstorms in May and the total expenditure on repair work amounted to nearly $0.5 million.
10.11. The routine work of the Division included overhaul and repainting of control gates, maintenance of access roads, treatment works and compounds, and the inspection and cleaning of service reservoirs.
10.12. New fresh water service reservoirs at Ho Man Tin, Tsuen Wan, and Yuen Long with a total capacity of over 31 million gallons and a salt water service reservoir at Tsuen Wan were commissioned. Kwun Tong Salt Water Pumping Station began operating with an initial capacity of 18 million gallons a day. A new tunnel system to carry raw water from Tai Lam Chung Reservoir to the Castle Peak area was put into service.
