【 摘 要 】

Problem statement: Sarawak River was a life-sustaining water source for the residents inKuching City and surrounding areas. Raw water is treated at Batu Kitang Water Treatment Plant(BKWTP) that supplies more than 98% of the total water production in Kuching City. The raw watersupply to BKWTP is not adequate to meet the ever increasing water demand. In order to overcome thisproblem, four projects had been implemented along Sarawak River for managing and securing watersupply to BKWTP. Approach: These four projects are construction of 1.5m height storage weir acrossSungai Sarawak Kiri river channel, Kuching Barrage and Shiplock, Bengoh Dam and KuchingCentralized Wastewater Management System (KCWMS). In 2005, 1.5 m height submersible weir wasconstructed across Sungai Sarawak Kiri channel for increasing the safe yield that can last until year2010. Kuching Barrage and Shiplock were commissioned in 2000 as barrier to avoid the salineintrusion reaching upper catchment. 24 telemetry stations were installed along Sarawak River formonitoring and regulating the water level. This will preserve high quality water storage at uppercatchment of Sarawak River. In year 2010, Bengoh Dam was constructed to ensure adequate raw waterwill be supplied to BKWTP for meeting the increasing water demand from 2010-2030. This reservoirwill store 144 million m³ of fresh water covering reservoir area of 8.77km². Beyond 2030, the watersupply shall not depend solely on fresh water. Results: Black and grey water in Sarawak Catchmentwas treated through Kuching Centralized Wastewater Management System (KCWMS) and recycledfor daily used. Conclusion: The treated water that comply Standard A water quality, can distribute fordomestic, industrial and irrigation used in nearest future. This will reduce the water demand solely onraw water and create a sustainable living in Kuching City. Beyond 2030, a few alternatives are alsoproposed for conserving and securing water supply for Kuching city.
