Abstract

Sewerage system provide infrastructure that conveys sewage or surface runoff using sewer network. Sewerage system requires perfect infrastructure to ensure that sewage can be channelled to the sewage treatment plant safely. Meticulous asset management for sewerage system is highly recommended to avoid any risk to assets that deliver sewage. Risk assessment strategy for sewerage asset is basically will evaluate the risk factor that influences the asset to encounter the potential problem. Current risk assessment framework didn't include spatial analysis to show the locations of the assets with risk. This study focused on the production of risk map that aims to analyse potential risk for asset management of sewerage system in Majlis Perbandaran Johor Bahru Tengah (MPJBT) using spatial analysis. The spatial analysis used in this study is slope analysis and asset's analysis focusing on age sewerage assets parameter. Combination of both factors show the risks that require more attention from the sewerage system management. The results show there were 90.8% of the asset have low risk, 8.9% have medium risk and 0.3% asset have high risk. These results can be used by the sewerage assets authority to make better decision in preventions and manage risk that could happen to the sewerage assets.
