In Bengaluru, BBMP officials have stated that the inflow of sewage into the Koramangala stormwater drain has decreased significantly, from 120 million litres per day (MLD) to around 8 MLD, after the initiation of the K-100 Urban Waterway Project. However, local residents and businesses near the drain have reported that the foul odor from the water has not decreased, and sewage-mixed water is still present. The K-100 project, funded with Rs 175 crore for redeveloping the drain infrastructure, is focusing on a 9.2-km stretch from KR Market to Bellandur Lake. BBMP plans to finish this project by the end of 2024. Efforts to prevent sewage from entering the drain include a new 5 MLD capacity sewage treatment plant at Kumbaragundi and the installation of concrete rings and plants to help naturally purify the water. Another sewage treatment plant is being built by BWSSB near Shantinagar to further prevent sewage from entering the drain. Various improvements such as building retaining walls, ground-level bridges, decorative lights, landscaping, pedestrian paths, fixing granite, and installing grills have been completed. Additionally, service roads have been constructed on both sides of the drain with pipelines to prevent rainwater runoff from entering the drain. The project was initiated in 2021 with the goal of completely stopping sewage inflow into the rajakaluve.It was meant to be completed by 2023, but it missed several deadlines thereafter.
