BDA completes 1,441 percolation wells in Bengaluru
The Bangalore Development Authority (BDA) has completed 1,441 rainwater-harvesting percolation wells to boost groundwater levels in the city. The project, conducted in collaboration with United Way of Bengaluru, aims to recharge over 184 million litres of water annually.
Why it matters
Urban water scarcity is a major issue in Bengaluru, and this infrastructure project represents a significant effort toward sustainable water management.
The Bangalore Development Authority (BDA) has completed 1,441 rainwater-harvesting percolation wells across 77 BDA parks and residential premises, with the infrastructure estimated to recharge 184.59 million litres (18.459 crore litres) of rainwater annually.
BDA Chairman N.A. Haris handed over the completed wells to the BDA authorities concerned at a programme held at Nadaprabhu Kempegowda Layout, 4th Block, on Thursday. The authorities will be responsible for their maintenance and upkeep.
The ‘One Billion Drops (OBD) – Groundwater Recharge through Percolation Wells’ project was implemented by United Way of Bengaluru (UWBe) in collaboration with the BDA between February 2025 and February 2026.
“Bengaluru’s water security depends on how effectively the city conserved and recharged water. Every drop we recharge today strengthens Bengaluru’s tomorrow. The percolation wells would help recharge groundwater and make the city more resilient,” Mr. Haris said.
