Floods and waterlogging are environmental problems that continue to recur in the city of Pekanbaru and have a significant impact on the social, economic, and quality of life of the community. This condition shows that the performance of urban drainage systems in collecting and draining rainwater is not optimal, especially during high rainfall. This study aims to analyze the factors that cause floods and inundation and assess the effectiveness of the existing drainage system in Pekanbaru City. The research method used is a qualitative descriptive approach, with data collection through field observations, interviews with relevant technical agencies, and analysis of related documents. The results of the study show that the main problems of the drainage system of Pekanbaru City include: the dimensions of the channel that are not in accordance with the water runoff capacity, blockages due to the accumulation of sediment and garbage, construction that does not pay attention to the infiltration function, and lack of periodic maintenance by the authorities. In addition, the weak public awareness in maintaining the cleanliness of the channels worsens flood and inundation conditions. Based on the results of the analysis, it is necessary to replan the drainage system as a whole, implement a flood mitigation-based space control policy, and increase community participation in urban environmental management. This integrated effort is expected to increase the effectiveness of the drainage system and reduce the risk of flooding in the city of Pekanbaru in a sustainable manner.
