Bengaluru Transforms Stinky Drain into Green Walkway
In Bengaluru, a very old and dirty waterway called the K100 was turned into a nice, green place to walk and play.
Before, it was full of trash and bad smells, but now it's clean and pretty.
The government and some other groups worked together to fix it.
They cleaned it up, planted trees, and made paths for people to walk on.
Now, kids can play there, and everyone is happy because it's much better than before.
This shows that even old, forgotten places can be made useful and beautiful again.
The K100 waterway in Bengaluru was transformed from a stinking open sewer into a green public space.
The restoration involved desilting, sewage treatment, and the installation of modern infrastructure, reducing sewage inflow from 130 MLD to 5 MLD.
The project included removing concrete barriers, laying walking paths, planting trees, upgrading bridges, and creating parks along the 11-kilometre stretch.
The K100 now serves as a flood protection measure and a shared neighbourhood space for residents.
The revival of the K100 demonstrates the potential for restoring Bengaluru's remaining 842 kilometres of Rajakaluves into lifelines for the city.
