Abstract: Flooding problem is often associated with clogging of drainage system contributed by large amount of litter. Gross Pollutant Traps (GPTs) function to trap gross pollutants and have been installed in urban waterways. However, the performances of GPTs are strongly dependent on the specific site criteria including type of land use, hydrological regime and maintenance frequency. The local authority is facing problems in conducting maintenance for the installed GPTs resulting in the clogging of system clogging. This leads to the flooding and contaminating of water at the downstream area. The current study aims to propose a proper management and planning tool for 151 units of proprietary GPTs installed in the urban areas under the project of River of Life (ROL). This study involves data collection of gross pollutants wet load trapped inside GPTs from 3 different types of land use (residential, commercial and mixed development). It takes into consideration of the cost associated in relation to Life Cycle Cost (LCC) and Cost Effectiveness Ratio (CER) of the installed GPTs in the study area. The results obtained from this study will help in assisting the engineers and local authorities to implement appropriate strategies for trapping gross pollutants in urban area, expanding the sources for managing gross pollutants in order to rehabilitate the river system and preparing budget allocation for GPTs operation and maintenance
