Sustainable Enhancement of Stormwater Management Through Permeable Pavement: A Case Study of Barisal City

Rapid urbanization and population growth in Bangladeshi cities, Barisal in particular, have created serious environmental issues including urban water-logging. While flooding prevents the infiltration of rainwater, the extensive concreting of the open space, the boulevards, and waterbodies have become a barrier to rainwater infiltration and flooding the daily life, the infrastructure, and the contamination of water. Therefore, there is a need for stormwater management. This study examines permeable pavement systems (PPS) systems as a potentially sustainable model. PPS systems recharge groundwater, manage surface runoff, and reduce flooding in residential, commercial, and industrial areas. The hydraulic modeling revealed that a 35-inch-deep PPS system with underdrain capabilities can hold approximately 865.41 cubic feet of stormwater. The study concluded that permeable pavement systems provide a sustainable long-term solution for stormwater management when conventional drainage isn't able to manage stormwater sufficiently. This is one mere action toward achieving Sustainable Development Goal 11 towards sustainable Cities and human. Thus, this study provides the foundation for urban sustainability, resilience, public health, environmental protection, and infrastructure sustainability and durability. A PPS system will provide immediate benefits to be achieved, however over time the long-lasting benefits will build stakeholder involvement from the community at large.
