BMC Plans Bioswales to Combat Mumbai Flooding
The city of Mumbai in India often gets flooded when it rains a lot.
The local government, called the BMC, wants to fix this problem.
They plan to build special areas called bioswales that help rainwater soak into the ground instead of flooding the streets.
These bioswales are like little gardens with special layers of sand and plants that clean the water and help it go underground.
The BMC also plans to build other things like sponge parks and special roads that let water pass through.
They hope these changes will make Mumbai safer and cleaner, especially when it rains a lot.
The project will cost a lot of money, but the government thinks it's worth it to protect the city.
BMC proposes Rs 12,705-crore plan to NDMA for Mumbai's climate resilience.
Bioswales to be constructed to filter and percolate rainwater, reducing flooding.
Initial focus on chronic flooding areas like Dadar, Matunga, and Andheri.
Project includes sponge parks, sluice gates, permeable pavements, and pumping stations.
Bioswales expected to improve groundwater levels, reduce waterlogging, and cool surface temperatures.
