1. Real-world problem it solves
Urban areas are increasingly facing the problem of waterlogging, flooding, and poor groundwater recharge. Traditional pavements made of dense concrete or asphalt prevent rainwater from seeping into the ground, causing stormwater runoff and clogging of drains. This leads to damage of roads, traffic disruptions, and depletion of underground water tables.
2. Gap in current solutions/market
- Conventional pavements are impermeable and worsen flooding.
- Stormwater drainage systems exist, but they are expensive, difficult to maintain, and often clogged.
- Some permeable pavement solutions are available, but they are costly and not widely adopted in developing countries.
3. Who benefits (users, buyers, community)
- Municipal authorities: Reduced stormwater management costs and less damage to roads.
- Citizens: Cleaner, safer streets without frequent waterlogging.
- Environment: Improved groundwater recharge and reduced flood risks.
4. Why this problem matters to me
In many cities, especially during the monsoon, waterlogging is a yearly struggle. I have personally seen streets submerged, causing traffic chaos and inconvenience. As a civil engineering student, I find it meaningful to explore innovative pavement technologies that not only solve flooding but also conserve water for future generations.
5. Technical details (optional)
Permeable pavements are made of porous concrete or interlocking pavers with gaps filled by gravel or grass. These allow rainwater to pass through into a sub-base layer, which filters and gradually releases it into the soil. Modular designs make them easy to replace and maintain.
