Mun River Improvements
underway to reduce the unpleasant odours created by polluted
sediment in the Shing Mun River, which empties into Tolo Harbour.
became contaminated in the 1980s when large amounts of industrial,
commercial, livestock and domestic waste water was dumped
untreated into the river. This problem was controlled by the
early 1990s under the Water Pollution Control Ordinance, resulting
in good water quality. But the dregs of the wastes are still
sitting on the river bottom, creating bad odours.
areas of work have been undertaken to improve the sediment
and odours. One area involves treating the sediment directly
through bioremediation, which involves injecting oxygen-releasing
solution into the sediment. This reduces odours and speeds
up the decomposition of organic pollution in the sediment.
area of work is the dredging of the Shing Mun River from the
Hong Kong Sports Institute to Man Lai Court. Large amounts
of contaminated sediment will be removed, thereby improving
the odour problem. Dredging will also help to control flooding
by removing sediment that has been blocking storm water drain
an artificial river bank will be built along a 250-metre section
near Man Lai Court,where there are relatively severe sediment
accumulations and odour problems.
million project, which began in May 2001, was proposed by
the EPD and is being carried out by the Civil Engineering
Department. The bioremediation, dredging and river bank work
will be completed in 2002 and further work will be carried
out if needed.
