In Bengaluru, BBMP officials have reported a decrease in sewage flow into the Koramangala stormwater drain from 120 million liters per day to around 8 MLD due to the implementation of the K-100 Urban Waterway Project. Despite this claim, local residents and businesses near the drain have stated that the foul odor and presence of sewage in the water remain unchanged.

The K-100 project, funded with Rs 175 crore by the government, aims to revamp the 9.2-km stretch of the stormwater drain from KR Market to Bellandur Lake. BBMP's engineering wing anticipates the project's completion by the end of 2024. Efforts to prevent sewage from entering the Koramangala Rajakaluve include the establishment of a 5 MLD capacity sewage treatment plant at Kumbaragundi and the installation of concrete rings and plants along the drain for natural water purification.

In addition, BWSSB is constructing a sewage treatment plant near Shantinagar, set to finish by year-end, to further prevent sewage discharge into the drain. Retaining walls, ground-level bridges, decorative lights, landscaping, pedestrian pathways, and other enhancements have already been completed by BBMP. Service roads with pipelines have been constructed to prevent rainwater from the roads entering the drain.

Initiated by BBMP in 2021, the project endeavors to enhance the overall condition of the Koramangala stormwater drain.It was supposed to be completed by 2023, but it missed several deadlines thereafter.
