Cemented surfaces stop rainwater from seeping into the soil. Instead of soaking down to become groundwater, water runs off into drains. This reduces groundwater recharge and leads to water shortages over time.

Class 5 Our Wondrous World Chapter 1 Water-The Essence of Life NCERT solutions
Cemented areas like roads, pavements and buildings block rainwater from entering the soil. When water cannot seep into the ground, it flows away through drains, causing less groundwater to be stored. This decreases the natural recharge of underground water. Over time, it leads to lower water levels in wells and borewells, especially during summers. Uncemented areas and rainwater harvesting help improve recharge.
