In Bengaluru, officials from BBMP have reported that the volume of sewage flowing into the Koramangala stormwater drain has decreased significantly from 120 million litres per day to approximately 8 MLD due to the K-100 Urban Waterway Project's implementation. However, despite this claim, local residents and businesses adjacent to the drain assert that the foul smell from the water has not diminished, and sewage continues to flow. The K-100 project, which involves the redevelopment of the 9.2-km stretch of the stormwater drain from KR Market to Bellandur Lake and has a budget of Rs 175 crore allocated by the government, is scheduled for completion by the end of 2024. BBMP officials detail that efforts to prevent sewage from entering the Koramangala Rajakaluve include the establishment of a 5 MLD capacity sewage treatment plant at Kumbaragundi near Kalasipalya and the installation of concrete rings and plants in the drain to naturally purify the water. Additionally, BWSSB is constructing a sewage treatment plant near Shantinagar, set to finish by the end of the year, that will further prevent sewage from entering the rajakaluve. The completion of retaining walls, ground-level bridges, decorative lighting, landscaping, granite fixtures, pedestrian paths, grills, service roads, and pipelines has already been achieved, according to BBMP officials.It was initially scheduled to be completed by 2023, but it subsequently missed several deadlines.
