        abstract = {Rapid urban expansion and infrastructure development have led to a substantial increase in impermeable surfaces such as concrete roads, pavements, parking areas, and rooftops. These surfaces significantly reduce natural infiltration of rainwater into the soil, resulting in excessive surface runoff, urban flooding, and depletion of groundwater reserves. Conventional storm water drainage systems are primarily designed to convey water away quickly rather than conserve it. The present research proposes an innovative and decentralized solution titled “Rainwater Harvesting Using Porous Manhole Covers.” The system integrates groundwater recharge functionality directly into existing road drainage infrastructure by replacing conventional solid manhole covers with structurally safe porous concrete covers. The porous structure allows rainwater to pass through interconnected voids into an underlying filtration chamber and recharge pit. M25 grade pervious concrete specimens were cast and tested for compressive strength as per IS 516 (Part 1):2021. The average 7-day compressive strength was found to be 22.13 N/mm², confirming adequate load-bearing capacity. Runoff estimation using the Rational Method indicates that each installation can recharge approximately 45,000–60,000 liters annually under average rainfall conditions. The proposed system is economical, environmentally sustainable, easy to retrofit, and suitable for urban.},
