HONG KONG LEGISLATIVE COUNCIL.

The Consulting Engineers reported favourably on the whole scheme and on the works already completed but suggested that the dam should be raised a further twenty five feet should borings on the site prove favourable. A series of core drill borings on the site have since been completed and the cores have been shipped home to the Consulting Engineers.
The site chosen for the dam is that originally selected by the P.W.D., the centre line being pushed some fifty feet upstream to allow for the extra width at the base.
The actual second section of the Shing Mun Scheme as now projected is the construction of a masonry dam giving an approximate depth of water of 200 feet on a site immediately upstream of the Shing Mun Gorge, giving a storage capacity of approximately 3,000 million gallons, and also of a subsidiary cut off masonry dam at Pineapple Pass approximately sixty feet high.
The direct catchment area of this reservoir is 2,900 acres which includes the 2,400 acres now partially tapped by the existing Shing Mun intake.
It is estimated that this reservoir will yield a supply of 9.25 million gallons per day over our driest known period, which means an addition of 6.25 million gallons per day to the Colony's supply, the difference of 3 million gallons per day being the supply now available from the existing intake and 1st Section Works.
The Dam is estimated to take five years to construct at an inclusive cost of $9,300,000, but it will of course be possible to utilize the water from the reservoir as the work proceeds.
This does not exhaust the gravity section of the Shing Mun Scheme as by means of catchwaters along the slopes of the surrounding hills at least another 6,000 acres can be tapped producing a further 9 million gallons approximately per day without further reservoirs. The catchwaters constitute what is known as the 3rd Section of the Shing Mun Scheme, and will be carried out when found necessary.
