We were commissioned by the Drainage Service Department (DSD) to conduct investigation, design and construction for the rehabilitation of about 2130m of existing sewage rising mains and the provision of additional sewage rising mains as duplicate in Sai Kung, Sha Tin and Tai Po. The project aims to enhance operation reliability of the sewerage system and to curtail the discharge of pollutants into the receiving water due to failure, malfunctioning and damage of existing rising mains. We also have to address the traffic issues, land issues and public concerns throughout the implementation of the project.
