Rapid urbanization has led to increased impervious surfaces such as conventional concrete and asphalt pavements, which prevent natural infiltration of rainwater into the ground. This results in groundwater depletion, surface runoff, and urban flooding. Permeable pavement is an innovative and sustainable solution that allows rainwater to pass through its surface and infiltrate into the underlying soil layers, thereby recharging groundwater. This paper studies the concept, working mechanism, components, and benefits of groundwater recharge through permeable pavements. The study highlights how permeable pavements can reduce runoff, improve water quality, and support sustainable urban water management. A simple model is also proposed to demonstrate the working of permeable pavement systems. This paper presents a detailed study on the concept, components, and working mechanism of groundwater recharge through permeable pavements. The benefits of this system, including runoff reduction, water quality improvement, and sustainable urban water management, are discussed. Additionally, a simple physical model is proposed to demonstrate the functioning of permeable pavement systems for educational and practical understanding.
