In Bengaluru, BBMP officials have reported that the flow of sewage into the Koramangala stormwater drain has decreased significantly, from 120 million litres per day to approximately 8 MLD, after the initiation of the K-100 Urban Waterway Project. Despite this claim, local residents and businesses near the drain insist that the foul odor persists and contaminated water continues to flow. The Koramangala Rajakaluve (K-100) project, funded with Rs 175 crore by the government for redeveloping the drain infrastructure, covers a 9.2-kilometer stretch from KR Market to Bellandur Lake and is expected to be completed by the end of 2024. To prevent sewage from entering the drain, a 5 MLD sewage treatment plant has been established at Kumbaragundi, along with the installation of concrete rings and plantings to naturally purify the water. Additionally, BWSSB is constructing a sewage treatment plant near Shantinagar, scheduled for completion by the year's end. Infrastructure enhancements, such as retaining walls, ground-level bridges, decorative lights, landscaping, pedestrian walkways, and service road improvements, have been completed. Efforts to prevent rainwater from the service road entering the drain include the installation of pipelines and construction of service roads on both sides of the rajakaluve. BBMP initiated this project in 2021 with the goal of improve the environmental conditions of the area.The project was intended to be finished by 2023 but missed multiple deadlines thereafter.
