Parched again: On Bengaluru’s drinking water woes

What Happened

Bengaluru East Taluka extracted 378% of its sustainable groundwater limit in 2025, compared to Karnataka's 66% state average. The city's crystalline rock base stores limited water and recharges slowly. Urban infrastructure suppresses rainwater percolation. A 2024 weak monsoon dried nearly half of 14,000 borewells. A government supply project achieved only midway coverage. Experts recommend decentralized wastewater recycling and converting Bengaluru into a 'sponge city' to capture monsoon runoff.
