Answer:

The human excreta and waste water are carried away by a network of underground pipes called sewers to the ultimate disposal site. Used for the first time in Calcutta (in India) in 1867. But even today, unfortunately not more than 20 percent of the urban areas in India can boast of this method of sewage disposal
