DDA plans biological treatment at Palam drain
The residents of Palam drain in Delhi have a happy news as the Delhi Development Authority (DDA) has planned biological treatment to remove the foul smell from the drain.
The DDA officials say that certain type of bacteria will be used to treat and clean the water from the Madhu Vihar to Nazafgarh.
As the drain covers large part of sub-city in Delhi, the residents have demanded the closure of all the drains with proper material to avoid the spread of foul smell.
