A majority of lakes and storm water drains in Bengaluru are severely polluted. These water bodies recharge groundwater, which means their pollutants are getting into our open wells and borewells.
Why do lakes like Sowl Kere and Arekere remain dry even during monsoons? The reasons are often man-made – building over stormwater drains, sewage, excessive borewell digging, etc. But there are solutions too.
Raw sewage, industrial effluents, solid waste dumping, can all lead to build-up of flammable gases in lakes. Why do these issues persist and what can be done to resolve these?
