That a complaint has been registered in the roster by me on 12/08/2018 and i personally met the je of the concerned area which is situated in lig flats loni road shahdara delhi. I and other surrounding residents met the je repeatedly in this regard but all is in vain. We have been advised that sucking machine is required to clear the sewer blockage. No action in this regard has been taken so far resulting the garbage of sewer backing in the residents house premises. I want to know weather it is the duty of residents to provide sucking machine. It is the duty of the concerned je/ex. En. To provide the sucking machine to clear the sewer.
