101. Throughout the year work was continually hampered through the tardy delivery of pipes from the United Kingdom.
Public Works Recurrent.
102. Maintenance of Sewers and Stormwater Drains: The sewer and stormwater drainage systems of the Colony were maintained in a satisfactory state. 386 repairs were carried out, 1,086 broken and unserviceable manhole covers, gratings and traps were replaced and 7,070 choked drains were cleared. De-sludging of the septic tanks at Repulse Bay, Deep Water Bay and Kai Tak was carried out during the year; that at Kai Tak presented a certain amount of difficulty in view of its location under the floor of a restaurant. In order to prevent pollution of the bathing beaches by the septic tank at Repulse Bay, arrangements were made to chlorinate the effluent before it is discharged into the sea. Work on the construction of tanks to enable this to be done was put in hand.
103. Typhoon and Rainstorm Damage: -No typhoons were experienced during the year and no major damage was caused to drainage works by rainstorms. Minor damage however was caused to a sewer and a stormwater drain near the seawall at Sai Wan Ho and repairs were carried out. The major part of the work under this head involved clearing the deposits of sand and silt from the various nullahs in the Colony.
104. Works Executed on Private Account:-The work carried out under this head was very considerably in excess of that which was anticipated. The following major works were carried out partly on private and partly on Government account:-Nullah training at Ming Yuen: Restoration of stormwater drains through the Hong Kong & Whampoa Docks Company's property at Hung Hom: Nullah extension at the Waterboat Dock, Lai Chi Kok. Minor works carried out and charged against private account included the strengthening of the nullah deck at Factory Street to take an additional tram track, the cutting of nullah walls to facilitate crossings by the various public utility companies and the following connections to, and extensions of, the Government drainage: -475 sewer connections, 77 stormwater drain connections, 1,489 feet of extensions to sewers and 1,435 feet to stormwater drains.
