Sewerage.
108. Water supply restrictions, the lack of nullah water and the drying up of wells during the dry season again caused minor nuisances by depriving the sewers of an adequate quantity of flushing water. On the other hand, numerous old private drains and channels improperly connected to the foul sewers caused the latter to surcharge and over-flow during times of heavy rain; many minor alterations were made correcting this trouble to some degree. Clearances of choked sewers and storm-water drains by the direct labour staff exceeded 8,500, a slight decrease compared with the previous year. Almost 1,500 small repair works were carried out.
109. Further preparatory work was carried out for schemes for the better disposal of sewage from the urban area, the object being a reduction of the nuisances which exist around most of the present harbour sewage outfalls.
110. Works continued on the replacement by cast iron piping of the old stoneware pipe sewer within the Waterworks catchment area around Mount Kellett whilst a number of old damaged sewers under roads carrying heavy traffic were relaid.
111. Approximately two miles of new public sewers and storm-water drains were constructed to serve new buildings.
Anti-malarial works.
112. No major scheme of anti-malarial drainage was carried out during the year. Existing works were maintained in a satisfactory condition, minor repair works being carried out as necessary.
Storm-water drainage.
113. Owing to the lack of foul sewers within areas occupied by squatters, all sullage water from such districts runs into storm-water culverts and nullahs. During the dry season decomposition of such refuse in open nullahs continued to cause offence. Arrangements were made to intercept some of the refuse inside the re-settlement areas.
