Sewerage System

Where does domestic wastewater go?

Each time we wash something or flush our toilets, water containing paper, cloth, soap, detergent, oil, grease, food scrap, faeces etc, and goes down the drain. This water accumulates and forms sewage. In large cities, this is known as municipal waste water.

Water Freshens Up: An Eventful Journey:

In a house (a public building) generally, there are two sets of pipes, i.e. one set of pipes brings clean drinking water into the house and the other set of pipes takes away wastewater (sewage) from houses. For proper sanitation a well maintained sewage system is required.

Sewerage System:

The pipes which carry away wastewater or sewage from houses and other buildings are burned under the ground. An underground pipe which carries away dirty drainage water and waste matter is called sewer.
