What is Koramanagala-Challaghatta (KC) valley project?

In a nutshell:

       The project is to fill the lakes of drought-hit Chikkaballapur and Kolar districts with secondary treated water from KC valley. The Secondary Treatment Plant (STP), located on the banks of Bellandur lake collects sewage water directly from the sewer lines for treatment. During the planning stage, the project was opposed by activists and scientist as it was carried out without Environment Impact Assessment(EIA) and public consultation. Crux of the matter was Secondary treatment. Scientist and Lok Adalat had recommended Tertiary treatment to avoid/mitigate groundwater contamination.

      The government went ahead with the project without addressing the concerns. Few days into it, so called treated water was frothing in the lakes of Kolar. Activist of Kolar, Shashwatha Neeravari Horata Samiti , went to high court. High court stayed the project, but then eventually allowed the project based on the water quality reports submitted by the government. High court ignored the scientists report by IISC which showed heavy metals. Mishap happened again. This time the activist went to Supreme Court which stayed the project.

Upcoming blog posts cover BET analysis of why this project does more harm than good. This was shared with the public during workshops
