details and the role of the 'sewerage system.​

Answer 1

The sewage system is used to collect this water and to clean it before returning it to the environment. Sewage represents a major stake both for public health and for sustainable development. At global level, the management of the sewage service is at the core of water issues.

The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
