Management of Environmental Risks
Due to the polluting nature of sewage, DSD recognises the potential threat of sewage overflows upon bathing beaches, the sea or even in the street. We place immense emphasis to possess readiness and the ability to respond to overflow of sewage from anywhere in the sewerage system or the treatment works. Contingency Plans are written for individual sewage treatment works and major pumping stations. Guidelines for classification, response and reporting of sewage bypass are agreed with the environmental authority and communicated to all relevant offices. The line of communication with the environmental authority is also well defined and the telephone list frequently updated.

Risk is minimised by inspection, desilting, proactive repairs and upgrading in order to ensure our system is in top performance. In 2003, 614 km of sewer were cleansed, 6351 m3 of silt were removed from sewers.
