The most infamous froth water of Bengaluru has now entered/reached Lakshmisagar lake in Kolar District with due thanks to the Rs.1342 crores Koramangala-Chalaghatta Valley project officially known as the Koramangala-Challaghattapura Valley lift irrigation project which seeks to fill 226 lakes in the district with treated sewage water from the State Capital, Bengaluru through a number of channels and pumps. A number of social activity groups opposed the project from the start on the grounds that the water treated is bound to aggravate the situation as it contains arsenic contents which affect the health of people and cattle.
This project’s main purpose was to recharge groundwater in the dried out lakes of Kolar, but the froth spewing water from past 2 days at Lakshmisagar lake confirms the dread and fear of villagers. The fear of villagers and activists being that due to this froth water the ground water may also get contaminated. It is clear the water treatment has not worked. All the villagers wanted was a source of water to drink and for farming purposes.
The Kolar region is the food bowl of Bengaluru as a maximum share of vegetables comes from there. Continuous discharge of polluted water may contaminate the already depleted ground water resources and in turn may contaminate the vegetables.
Residents of Kolar complain that before it was only odor but now they fear that the odor and froth has intensified. Farmers fear that the crops grown with the help of this water may not survive. Nearly 70% of Kolar’s farmers depend on farming and lakes are the only option left o recharge the ground water.
After all these problems surfaced, the blame game has started. The BWSSB says that the water from supply point is tested and is in-fact intact, beyond that the responsibility falls on the Minor Irrigation Department.
According to A.N. Yellappa Reddy, an environmentalist and former Lok Adalat member, the froth in water has aerosol suspension containing both bacteria and virus and is a mini chemical and biological bomb. The villagers say the water coming from the pipeline is visibly dark in colour. Though the people of Kolar may not suffer the effect immediately, there will be a long term impact from it.
