Scavenging.
160. Scavenging is carried out departmentally. There are twenty-three refuse lorries in use, fifteen being for Hong Kong and eight for Kowloon. 467 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 shallow inlet with the ultimate object of reclaiming a large area and forming sites for factories.
Conservancy and Sewerage Disposal.
161. The collection and disposal of night-soil in the Colony is carried out partly by the bucket system and partly by water carriage.
162. The excrement is removed by night from the latrines to a special fleet of junks which convey it up river to China where it is utilised as manure for the mulberry trees on which the silk worms feed.
163. Owing to the limitations of the water supply on the Island and the need for economy in the matter of consumption, it is necessary to restrict the number of water closets served by the public mains.
164. Where a sufficiency of water can be obtained from other sources, such as wells or streams, and the conditions otherwise are suitable, water closets are allowed. With regard to effluents, some enter the public sewers direct, some pass to biological tank systems to be treated before final discharge.
Drainage.
165. Drainage both surface and subsoil is controlled by the Public Works Department. $154,000 was entered in the 1936 Estimates for a programme which included drainage, training of nullahs and sewerage. $20,000, which includes costs of resumption, was provided for anti-malaria works.
Water Supplies.
166. The water supplies of Hong Kong and Kowloon are in charge of the Water Works Branch of the Public Works Department.
167. All the water is surface water and almost of it is collected from catchment areas which are free from ordinary risks of pollution. The water, after storage for a longer or shorter period in impounding reservoirs, is filtered in some cases by slow sand filters, in others by the rapid system, and finally it is chlorinated.
