Write, in brief, about the basic details and the role of the ‘sewerage system’.


just as a network of pipes brings clean water to our homes, a network of pipes takes the waste water, or sewage, away. This network of pipes is called the sewerage system.

Role of the sewerage system

It carries the sewage, from its source, to a waste water treatment plant. The waste water is cleaned, and purified, by various processes at these treatment plants. The water, thus, treated and cleaned, is then allowed to mix with river or sea water.
