Delhi Jal Board — Choked and overflowing sewer, at kalkaji extension 1/8 behind kalkaji police station

Address: New Delhi, Delhi, 110019

Please be informed that we are suffering and are forced to live in most unhygenic conditions due choked and overflowing sewer behind our house at 1/8 Kalkaji Extension, Behind Kalkaji Police station.
Several complaints have been made through phone number 1916, and also through the online but no concrete action has been taken.
We request that the complete sewer line behind the be cleaned at the earliest so that the premises becomes livable.
Please understand that the sewer is flowing from back to the front through the house and have attached photgraphs of the kitchen for reference.

Hope someone will put in efforts to respect healthy living conditions and standards.
