The Government of Karnataka proposes to pump 770 MLD of treated wastewater from Bengaluru City to the neighbouring drought-prone districts of Kolar, Chikkaballapur and Bengaluru Rural. The treated wastewater will fill up 134 tanks in these districts and will benefit the farmers by increasing the groundwater table through recharge from the tanks. This is part of the KC Valley pumping scheme. 

As part of this project, farmer interviews were conducted around lakes yet to receive treated wastewater (Holali, Markalaghatta), lakes rejuvenated through World Bank JSYS project (Pichguntlahalli, Hosakere) and a lake which has received treated wastewater (Lakshmisagara). A total of 10-15 farmers were interviewed near each lake. Secondary data on drought, climate change, wastewater reuse was also collected from KSNDMC and other available case studies. An Environment Impact Assessment (EIA) was also conducted in 4 lakes to document and understand the link between the lake, water, vegetation and the treated wastewater.
