I Am Residing at LIG colony, Prasad Nagar, Karol Bagh. we are facining drinage problem in our colony. The seewage line connecting the house hold line are not cleaned regularly. Due to which waste water is not going out properly. instead it is coming back to flats. it may cause serious health problems later. The ground floors flats are only facing this problem. we have make the house hold sewage line to be cleaned in every alternative day. causing lot of waste of time and money. if the duty of workers entrusted for the job done regularly we might have not faced this problem.
