throughout the year. Sand is dredged from the seabed by a contractor operating under a Government contract and delivered to depots for subsequent sale by Government to the public. Sand for building purposes is only in exceptional cases taken from waters adjacent to the coastline of Hong Kong and then only from carefully selected sites; the reason for this is to preserve the amenities of the Colony's coastline. To supply the large quantities of sand to meet Colony-wide demand, the sand contractor has therefore to dredge sand from deposits in coastal waters not adjacent to the Hong Kong coastline under special arrangements made with the appropriate Chinese authorities. This year 1.22 million cubic yards out of total sales of 1.25 million was dredged from Mirs Bay near the mainland opposite Ping Chau Island, the rest coming mainly from stock. Special silica sand for industrial use is also sold at the standard price for direct collection by the purchasers from sites in the New Territories. The New Territories Administration charges a fee of $6.00 per cubic yard for small quantities of river or beach sand collected by villagers for village works.
6.70 There are six sand-selling depots, at North Point on Hong Kong Island, at Cheung Sha Wan and Kwun Tong in Kowloon and at Sha Tin, Tai Lam Chung and Silver Mine Bay in the New Territories. These depots were open for business on 354 days during the year. In addition to the selling depots there is a sand storage site at Kennedy Town on Hong Kong Island.
6.71 Plans were made for reprovisioning the Cheung Sha Wan, Sha Tin and Tai Lam Chung sand depots at other sites as essential marine access to the existing ones is to be cut off by further works to be carried out seawards of the existing depots.
Laboratory
6.72 The establishments operated by the Quarries Section for testing construction materials include the main P.W.D. Laboratory at North Point and three branch laboratories, one at Farm Road in Kowloon and one at each of the Government quarries at Mount Butler and Diamond Hill. Testing of materials for the Public Works and other Government Departments and for the public is carried out at the North Point and Farm Road laboratories. The two quarry laboratories test the materials produced at these quarries.
