Delhi Development Authority [DDA] — overflowing manhole

Address: New Delhi, Delhi, 110058

Hi,
There is a manhole in the lane (Street no 28) right behind my house which has been overflowing for the past 6 months. I have complained to the authorities on various occasions but the drainage water is continuously overflowing. The stench from the water poses health issue for the residents living nearby. Inspite of complaining we have not got respite from this issue. Please look into the issue and do the needful at the earliest.
Thanks, krithika
Location where manhole is overflowing, street no 28, shiv nagar, janakpuri, behind wz522 house
