Located strategically in Bengaluru-Chennai industrial corridor, Anekal taluk has emerged to be Bengaluru’s industrial hub, especially for the highly polluting Chemical & Pharmaceutical industries. While this industrial development is a remarkable economic success for Bengaluru vis-a-vis India, unfortunately, it has also resulted in extraordinary negative externalities in the form of pollution, esp. of rivers, lakes & underground aquifers.

The grossly polluted and overexploited underground aquifers are the source of drinking water. As a result, taluk’s population and economic activities are in utter need of water, not just any quality of water, but clean & safe water. The need for clean water in the taluk’s Pharmaceutical industries has resulted in Bengaluru Water Supply and Sewerage Board (BWSSB) supplying Cauvery water to many Pharmaceutical industries, including Biocon. However, ordinary citizens still depend on vanishing & unsafe groundwater for drinking. So, there is an urgent need to address quality, quantity, and equity concerns in the heavily water-stressed region of Anekal.

This platform provides the necessary data points for citizens  & policymakers to address these concerns.
