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.
