142. The rate of building development showed no diminution and drainage extensions totalled nearly 10 miles of foul sewers and storm-water drains. Approximately two thirds of these extensions served private estate developments and were carried out at the cost of the developers.
143. During the year this office carried out minor works in Government air raid tunnels and was responsible for their maintenance.
Sewerage
144. Owing to the shortage of rain during the winter, nullah supplies of flushing water were unusually low and gave anxiety in some instances. This shortage, together with the restricted hours of mains water supply, resulted in insufficient flow in many of the sewers and a large number of chokes and other minor nuisances occurred. The sewer gangs cleared nearly 9,000 chokages during the year, representing an increase of about 1,000 over the last year and 1,500 over the previous year.
145. Work continued during the year on the construction of the Yaumati Drainage Scheme and most of the ancillary relaying works were completed except for the final connexions to the main interceptors. The 66 inch diameter concrete outfall sewer was laid from a point inside the Cosmopolitan Docks extending for 1,200 feet west-wards along the sea-bed. One pumping station, at Nanchang Street, was completed, and the second station, at Mongkok Road, was constructed to ground level and work was in hand at the end of the year on the foundations of the screening plant building. None of the plant ordered from England had arrived by the end of the year.
146. The relief sewer in the Wongneichong Valley which was commenced last year was completed.
147. Design work on the sewerage scheme for the Wanchai area was carried to an advanced stage and a contract was entered into for the delivery of the reinforced concrete pipes for the main interceptor along Gloucester Road.
