increase in turbidity of the receiving water which may adversely
affect the ecosystem.
Prior to making a discharge, the responsible person for the discharge
should submit an application to EPD for a discharge license. Under the
Water Pollution Control Ordinance, it is an offence to discharge polluting
matter in a water control zone without a valid license, or to discharge
effluent in breach of the terms and conditions specified in the discharge
license granted by the Authority. The contractor has the responsibility to
ensure compliance with all legislative control requirements. Apart from
obtaining a valid discharge license before the commencement of any
discharge, the contractor must take all necessary steps to comply with
the terms and conditions of the license. This requires due consideration
to be given at the planning stage of a construction project. Attention
should be paid to the wastewater characteristics, to minimise the quantity
of pollution loads (both in terms of flow and concentration), plan and
install proper site drainage to intercept stormwater run-off from outside
the side and collect silt carrying site run-off to silt removal facilities;
design and construct appropriate wastewater treatment facilities, provide
the necessary training to the site personnel as well as constant on-site
supervision and monitoring of the environmental performance. All
wastewater treatment facilities should be well maintained to achieve the
desired performance.
