To provide relief to the continuous droughts that have occurred in the Kolar and Chickballapur districts (Semi-arid Deccan area) for the last ten years, the Govt. of Karnataka evolved a scheme to fill up the village tanks (locally known as “Kere”) of these two districts with secondary treated water from several STPs situated in Bangalore. This effort commenced in 2018. It was meant to function as an indirect recharge of groundwater, and all villages have been cautioned not to use this water directly. Needless to say, all villages here were provided with protected drinking water systems earlier. This approach has now become a huge success, and today, close to 500 MLD of treated water from Bangalore STPs is being filled into these tanks, out of which 380 MLD is being pumped under the KC valley project. The treated water generally meets the new NGT standards of 50/10/10/1 water quality (COD, BOD/TN/PO4-P as mg/L). This being a Yeoman and a Pioneer effort in India and across the World, this was being monitored closely and observed by all. The IISc (CST Centre) was asked to monitor the overall outcomes in terms of water quality (environmental) being transferred and its safety to agricultural operations, the nature of the change in agricultural practices, the potential implications of such an endeavour (loosely paraphrased as ‘Environmental Impact Assessment’, or EIA) that addresses the present and the future of such an endeavour. The current environmental impact analysis goes beyond the mere reconstruction of environmental problems, and the emerging outcomes of this ongoing analysis are as follows
