The World Bank has approved a USD 426 million (Rs 3,700 crore) financing for the ‘Karnataka Water Security and Resilience Programme’ to rejuvenate Bengaluru’s 183 lakes. These water bodies, which act as natural sponges during heavy rainfall, are central to the city’s environmental and flood resilience.

Cleared on June 23 by the World Bank's Board of Executive Directors, the programme is expected to enhance water security for over four million Bengaluru residents. One of the key features of the initiative is the use of advanced flood modelling through computer simulations to anticipate the location, timing, and intensity of flooding. This will allow for more strategic investments in the city's long-term climate resilience.

Additionally, nine sewage treatment plants (STPs) will be constructed to stop untreated sewage from entering lakes and drains. Treated wastewater will be reused for industrial purposes and groundwater recharge. Over 1,00,000 households will also gain access to sewerage connections for the first time, marking a major step in improving urban sanitation and sustainable water management in Bengaluru.
