Abstract

The centralized sewerage system for Kuching City currently under construction and this project is expected to be completed by October 2012. This system shall collect all the wastewater through sewer network to a centralized treatment plant and using the activated sludge system to treat the wastewater. The effluent after being discharged into a constructed wetland before finally flowing into Sarawak River is believed to comply with Standard A of the Environmental Quality Act requirement. Prior to this, Sarawak River and its tributaries within the study area are polluted. The main source of the pollution is raw and insufficiently treated sewage and wastewater, which is eventually drained to Sarawak River. The water quality of different point of the entire river system has been classified according to the Malaysian Interim National Water Quality Standards (NWQSM). The water quality in confluent of Sungai Bintangor, Sungai Sarawak, Holiday Inn, confluent of Sungai Padungan, confluent of Sungai Sekama, Sungai Sarawak, Bintawa Causeway and Bako Causeway is polluted and falls between the class III and class IV of the NWQSM. Very high concentrations of BOD and COD are observed in samples tested. The content of bacteria is extremely high and the water poses a health risk. The water quality in Sungai Sarawak, Satok Bridge, Upstream and Downstream Barrage are slightly polluted and falls between the class II and class III of the NWQSM.
