When it rains, Yemalur lake starts frothing

For the residents near Yemalur lake, the on-setting of monsoon is bad news. Every time it rains the lake starts frothing emitting an unbearable stench and posing a health hazard. Just a few minutes of breathing its toxic air, makes you nauseous. Many residents say when the lake starts frothing, they prefer to stay inside their homes.

The froth also spills over to the road forcing commuters to navigate through it. It slows down the movement of vehicles and triggers traffic jams.

Yemalur Lake is located in the vicinity of the Bellandur lake, which also starts frothing when it rains. The daily free flow of untreated sewage water and industrial effluents into these water bodies is the main culprit.

Thanks to the inflow of pollutants, the ammonia and phosphate level in these lakes has shot up and the dissolved oxygen come down leading to formation of froth.

Experts say Yemalur Lake should be managed with a mini sewage treatment plant and an artificial wetland. The raw sewage should be treated and run through the wetland before it is let into the lake.

Last year, BBMP and pollution control board officials had assured that they would take steps to tackle the problem.  But residents say officials have failed to act and the problem has come back again this rainy season.
