In Bengaluru, officials from BBMP have reported that the sewage flow into the Koramangala stormwater drain has decreased from 120 million litres per day to approximately 8 MLD following the implementation of the K-100 Urban Waterway Project. Despite this claim, local residents and commercial establishments adjacent to the drain state that the foul odor from the water has not diminished and sewage-mixed water continues to flow. The K-100 project, with a budget of Rs 175 crore allocated by the government for revamping the drain infrastructure, covers a 9.2-km stretch extending from KR Market to Bellandur Lake. Engineers from BBMP anticipate completing the project by the end of 2024.

In an effort to prevent sewage from entering the Koramangala Rajakaluve entirely, BBMP has set up a sewage treatment plant with a capacity of 5 MLD in Kumbaragundi near Kalasipalya. This plant treats the sewage before releasing it into the stormwater drain. Additionally, BBMP has placed concrete rings and planted specific vegetation in the middle of the Rajakaluve near Shantinagar to help absorb and naturally purify the water. Meanwhile, BWSSB is constructing another sewage treatment plant near Shantinagar, scheduled for completion by the year's end, to further prevent sewage intrusion into the Rajakaluve.

BBMP reports that various enhancements, such as constructing retaining walls, ground-level bridges, decorative lighting, landscaping, granite fixtures, pedestrian walkways, and grills, have been finished. Service roads have been built on both sides of the Rajakaluve, with pipelines installed to prevent rainwater from flowing into the drain from these roads. The project, initiated in 2021, aims to fully revitalize the Koramangala Rajakaluve for the benefit of the community.To finish it by 2023, however, it later failed to meet multiple deadlines.
