In Bengaluru, BBMP officials have reported that the sewage flow into the Koramangala stormwater drain has decreased from 120 million litres per day (MLD) to around 8 MLD after the implementation of the K-100 Urban Waterway Project. Despite this claim, local residents and commercial establishments along the drain have noted that the foul odor from the water has not diminished, and sewage-mixed water continues to flow. The K-100 project aims to revamp the 9.2-km-long stretch of the stormwater drain from KR Market to Bellandur Lake, with a government allocation of Rs 175 crore. The BBMP engineering wing anticipates completing the project by the end of 2024. To prevent sewage from entering the Koramangala Rajakaluve, a 5 MLD capacity sewage treatment plant has been installed near Kalasipalya. Additional efforts include the installation of concrete rings and plants in the rajakaluve to naturally purify the water. BWSSB is also constructing a sewage treatment plant near Shantinagar to further prevent sewage from entering the rajakaluve. Infrastructure improvements such as retaining walls, bridges, lighting, landscaping, pedestrian pathways, and service roads have been completed by BBMP, along with measures to prevent rainwater from the roads from entering the drain. The project, which was initiated in 2021, aims to enhance the drainage system and water quality in the area.To complete it by 2023, but it missed several deadlines afterwards.
