In Bengaluru, BBMP authorities have reported a decrease in sewage flow into the Koramangala stormwater drain, from 120 million litres per day to approximately 8 MLD, following the launch of the K-100 Urban Waterway Project. Despite this claim, local residents and businesses alongside the drain insist that the foul odor and mixed sewage flow remains unchanged. The K-100 project, funded with Rs 175 crore by the government for drain infrastructure redevelopment, covers a 9.2-km stretch from KR Market to Bellandur Lake. BBMP's engineering division anticipates project completion 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. Additionally, BBMP has installed concrete rings and certain plants along the rajakaluve for natural sewage absorption. BWSSB is constructing a sewage treatment plant near Shantinagar, due to be finished by the year's end, aiming to prevent sewage flow into the rajakaluve completely. The construction of retaining walls, ground-level bridges, decorative lights, landscaping, granite fixing, pedestrian ways, and grills has been completed, along with the establishment of service roads and pipelines to prevent rainwater from entering the rajakaluve. BBMP initiated the project in 2021 with the goal of comprehensively upgrading the city's stormwater drainage system.It was supposed to be finished by 2023, but it missed several deadlines thereafter.
