In Bengaluru, officials from BBMP have reported that the sewage flowing into the Koramangala stormwater drain has decreased significantly, from 120 million litres per day to approximately 8 MLD, as a result of the K-100 Urban Waterway Project. Despite this claim, local residents and businesses near the drain insist that the foul odor of the water has not improved, and contaminated water continues to flow. The K-100 project, allocated Rs 175 crore by the government for redeveloping the drain infrastructure, covers a 9.2-km stretch from KR Market to Bellandur Lake and is expected to be completed by the end of 2024. Efforts are being made to prevent sewage from entering the drain, including the establishment of a 5 MLD sewage treatment plant near Kalasipalya and the installation of concrete rings and certain plants in the drain itself for natural purification. Additionally, a sewage treatment plant near Shantinagar is under construction by BWSSB and is set to be completed by the end of the year to further limit sewage entry. Various improvements have already been made, such as building retaining walls, ground-level bridges, service roads, and pipelines to direct rainwater away from the drain. The project, initiated in 2021 by BBMP, aims to tackle the issue comprehensively.To finish it by 2023, but missed multiple deadlines thereafter.
