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, after the implementation of the K-100 Urban Waterway Project. However, local residents and businesses near the drain have noted that the foul odor and sewage-mixed water have not diminished. The K-100 project, allocated Rs 175 crore by the government for drain infrastructure redevelopment, covers a 9.2-km stretch from KR Market to Bellandur Lake and is expected to be completed by the end of 2024. To prevent sewage from entering the Koramangala Rajakaluve, a 5 MLD sewage treatment plant has been set up at Kumbaragundi near Kalasipalya, while efforts are underway to construct a sewage treatment plant near Shantinagar by the end of the year. BBMP has also installed concrete rings and plants along the rajakaluve to naturally purify the water. Various other improvements, including retaining walls, decorative lights, landscaping, pedestrian ways, and service roads with pipelines to prevent rainwater entry, have been completed as part of the project initiated in 2021.It was supposed to be completed by 2023, but it missed multiple deadlines.
