Scavenging. Scavenging which used to be done by contract is now carried out departmentally. There are 16 refuse lorries in use, 11 for Hong Kong and 5 for Kowloon. Tons were collected daily and removed to 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 from the land. Some of the refuse from Kowloon was used to reclaim low-lying land near the sea-shore.
Sewage Disposal.-The collection and disposal of night-soil in the Colony is carried out partly by the bucket system and partly by water carriage. With regard to the bucket system, arrangements are made with a Contractor for the removal and disposal of excrement under conditions laid down by the Sanitary Board. Human night-soil is a valuable commodity in China where it is used as a fertiliser for the fields, and there is no difficulty in securing a Contractor who will pay a considerable sum for the sole right of removal. Under the present arrangement, the Contractor pays $12,120 per annum to revenue for the contracts for Victoria and Kowloon. Revenue from this source is gradually diminishing owing to the substitution of water closets for pail closets.
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.
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. Where a sufficiency of water can be obtained from other sources such as wells or nullahs, water closets are allowed. With regard to effluents, some enter the public sewers direct, others pass to biological tank systems to be treated before final discharge.
Drainage (Subsoil and Surface).-Drainage, both subsoil and surface, is controlled by the Public Works Department.
Water Supplies.-The water supplies of Hong Kong and Kowloon are in charge of the Water Works Branch of the Public Works Department.
All the water is surface water collected from catchment areas which are free from ordinary risks of pollution.
The water, after storage for a longer or shorter period in the impounding reservoirs, is filtered, in some cases by the slow sand system, in others by the rapid system and finally chlorinated.
