Residents of Allwyn Colony in Kukatpally, Hyderabad are having a tough time dealing with toxic foam entering their home. The same incident happened near Dharani Nagar, which lies close to Kukatpally Nala - one of the four major drains that dump industrial effluents into the Hussain Sagar Lake, and eventually the Musi River. Not only residents, but regular commuters are also facing inconvenience with the foam.
