2. Site of Destructors and Pumping Station :-The site shown on plan has been chosen chiefly on account of the desirability of having the destructors as far removed as possible from the densely populated parts of the City. It forms part of the scheme of reclamation referred to on page 40 in the report on the commercial development of the Port of Hong Kong by Mr. John Duncan dated the 12th December 1924 and entails the building of a deep sea wall and reclamation. It is desirable to keep the installation within harbour limits east of Sulphur Channel, as the removal of refuse to this point is less likely to be affected by typhoons and adverse weather. The destructors are shown on part of the site nearest the harbour front to allow of rapid and cheap handling of refuse by water transport. It would probably be found economical for all refuse east of Western Market to be water-borne. From experience gained of the working of Destructor plants in several towns in England during the years 1904-1910, I am strongly of the opinion that they can be successfully operated in Hong Kong, but whether they would or would not be a sound business proposition and a Sanitary improvement worth the cost as compared with the present method of refuse disposal at sea, and whether the power generated could be economically used for any large Government buildings and plants other than pumping for a salt water flush system, (and I am inclined to think it
