K100 is a 12km long storm water drain that starts under the iconic Shantala Silks at Majestic and flows down via Shantinagar and Koramangala into Bellandur Lake. It is the primary drain of the Koramangala Challaghatta valley.

It was originally a natural seasonal stream that got neglected and encroached upon little by little as its catchment area urbanised. By the 2000's the K100 was in a very poor condition. There were over a hundred million litres per day of sewage flowing into it illegally. People used it as a dumping ground for dry waste.

In 2020, the Government of Karnataka decided to revive the drain and convert it from an open sewer into a public space. Over the last two years they have removed 30000 tons of silt, diverted 100 MLD of sewage, and rebuilt the bridges and retaining walls along the stretch.

Today, the project is close to completion and is expected to open to the public in 2024.

In this film we meet people who live by the drain and speak to the architects, engineers and government officers who have worked on the project.
