Drainage
All the urban areas and the newly developing townships have been provided with waterborne sewerage systems, although in a few areas there are still some old buildings which are not yet connected to the public sewers. Building developments are kept under surveillance and the hydraulic conditions of existing sewers are con- stantly reviewed; with suitable arrangements made to ensure that no overloading will occur. Accordingly, new sewers were laid in Sham Shui Po, Lai Chi Kok, Wan Chai, Happy Valley and North Point.
The planning and construction of sewage screening plants and submarine out- falls continued. Construction of a second new submarine outfall off Wan Chai Reclamation and a sewage screening plant in Lai Chi Kok was started.
