280. The expected increase in demand for water materialized, due to continued industrial expansion and an accelerated rate of construction of multi-storied domestic and office blocks. The quantity of water required for new resettlement estates also greatly increased.

During this period only five hours supply daily (from 25th April, 1958 to 1st May, 1958) and four hours supply daily (from 2nd May, 1958 to 15th May, 1958) could be given. The enforced storage in the Tai Lam Chung Reservoir due to the closure of the tunnel made a 10-hour daily supply possible from 16th May until 9th July. The storage position then indicated the need to return to the 5-hour daily supply period and this remained in force until 31st July. Fortunately, very heavy rain fell in the last few days of July and the Island reservoirs, 40% full on the 25th, all overflowed on the 31st. The above average rainfall, especially in September, permitted a 10-hour daily supply from 2nd August to 26th November, with intermittent periods of 16 hours. All reservoirs with the exception of Tai Lam Chung overflowed on the 3rd October, giving a water storage of almost exactly 10,000 million gallons, but with the dry season ahead it seemed advisable to reduce the daily supply hours to eight on 27th November to avoid the possibility of severe restrictions at the end of the dry season. Even so, in spite of an abnormally wet February, it became necessary to reduce the daily supply hours to three on 14th March and this restriction still remained in force at the end of the period under review. The usual full supply came into force over Chinese New Year,
