GENERAL MEASURES OF SANITATION.
DOMESTIC CLEANLINESS.
129. Every domestic building or part of a building occupied by the members of more than one family must, unless especially exempted by the Sanitary Board, be cleansed and limewashed throughout by the owner, to the satisfaction of the Board, not less than once in every year, and notice in writing that such cleansing and limewashing has been completed shall be sent by the owner to the Secretary within three days after the date of completion.
130. It is the duty of the occupier of any domestic building to cause such building to be kept in a cleanly and wholesome condition and to see that the drains, traps, gratings, fall pipes, and sanitary fittings and appliances, are free from obstruction and in an efficient state of repair.
131. In Hong Kong there are 13,829 Chinese houses with 46,903 floors; in Kowloon there are 10,607 houses and 31,908 floors. During the year 152,594 floors in Hong Kong and 83,179 floors in Kowloon were cleansed. During the cleansing process all the furniture is moved and the floors and woodwork washed with kerosene oil emulsion.
132. Considering that each inspector has to supervise a district with approximately 25,000 inhabitants, most of whom are ignorant of the rudiments of sanitation, the thoroughness of the cleansing operations is remarkable.
SCAVENGING.
133. Scavenging is carried out departmentally. There are twenty-one refuse lorries in use, fourteen being for Hong Kong and seven for Kowloon. 430 tons of refuse was collected daily and removed to the various refuse depots. The bulk of the refuse was ultimately disposed of by dumping in the sea at a distance from the city and in such a situation where the currents run in a direction away from the island. Some of the refuse from Kowloon was used to reclaim low-lying land near the sea-shore.
