KUCHING (May 22): A hydrographic survey is urgently needed to identify the root causes of flooding in Bintulu, particularly to assess the depth and sedimentation levels of local rivers that contributed to severe inundation earlier this year, said Jepak assemblyman Iskandar Turkee.
Speaking during his Motion of Appreciation on the Yang di-Pertua Negeri's address at the Sarawak Legislative Assembly (DUN) sitting today, Iskandar highlighted that the flooding on January 29 had paralysed activities in the division, especially in the town area.
'Besides natural causes, we believe there are other contributing factors to the disaster. One of them is the weakness in the drainage system in Bintulu, which prevented Sungai Sebiew from effectively discharging excess water, leading to a rapid surge in river levels,' he said.
To address the problem, Iskandar proposed several risk management strategies, starting with the hydrographic survey.
'To ensure smooth river flow from upstream to the estuaries of Sungai Sebiew and Sungai Kemena, a hydrographic survey must be conducted to determine the depth and sedimentation that may be causing floods,' he said.
He added that the survey's findings would enable the government to implement targeted short- and long-term flood mitigation measures.
'These measures may include river dredging, construction of flood retention ponds, upgrading of drainage systems, expanding monsoon drains in densely populated residential areas, and relocating residents affected by floods,' he said.
Iskandar also stressed the importance of enhancing communication and utility infrastructure resilience during disasters.
He suggested that power supplies for petrol stations and telecommunications towers be backed by standalone systems, and that substations be constructed on elevated terrain to prevent flood damage.
'This is to ensure uninterrupted fuel supply and functional communication systems during flood emergencies,' he said.
Furthermore, Iskandar advocated for broader adoption of satellite communication technology, such as Starlink, especially in rural areas, with solar power as a sustainable energy source.
Lastly, he called for the establishment of a Smart Data Utility Bank encompassing every division, district, town, village, and longhouse to maintain a comprehensive inventory of key infrastructure locations.
'This would help the government manage risks more systematically, swiftly, and effectively by enabling relevant departments or agencies to respond accordingly,' he said. Bintulu DUN flooding hydrographic survey Iskandar Turkee lead
