Bengaluru: Officials from BBMP have reported that the amount of sewage flowing into the Koramangala stormwater drain has decreased from 120 million litres per day to around 8 MLD after the implementation of the K-100 Urban Waterway Project. Despite this claim, local residents and businesses along the drain argue that the foul smell and the presence of sewage in the water have not improved. The K-100 project, funded by the government with Rs 175 crore, aims to rebuild the drain infrastructure along a 9.2-km stretch from KR Market to Bellandur Lake. BBMP expects to finish the project by the end of 2024. To prevent sewage from entering the drain, a 5 MLD capacity sewage treatment plant has been established at Kumbaragundi near Kalasipalya. Additionally, BBMP has introduced concrete rings and planted specific vegetation along the drain to naturally filter and clean the water. BWSSB is constructing a sewage treatment plant near Shantinagar, set for completion by the year-end, to further prevent sewage from entering the drain. BBMP has also completed various enhancements, such as building service roads, installing pipelines to divert rainwater, constructing retaining walls, ground-level bridges, decorative lighting, landscaping, granite fixtures, pedestrian pathways, and safety grills. The project, launched in 2021, aims to completely revamp the Koramangala Rajakaluve.The project was expected to be finished by 2023, but it missed multiple deadlines afterward.
