The wastewater collected in municipalities is known as sewage.
What are the different sources of sanitary sewage?
Sa?nitary wastewater comes from the following sources:
1: Water supplied by water authorities for domestic usage, after desired use, is discharged in to sewers as sewage.
2: Water supplied to the various industries for industrial processes by local authority. After use in different industrial applications, some amount of waste water is generated which is discharged as wastewater. When supplied from the water supply or from the private sector, it is used for various purposes such as bathing, cleaning equipment, flushing toilets and urinals, and cleaning. The water used for all the above needs forms wastewater. Industry uses water to manufacture various products and develops wastewater.
3: Water supplied to schools, cinemas, hotels, hospitals and commercial facilities. Some of this water will flow into the sewer after being used as needed.
4: Water pumped from a well by an individual to meet the needs of the home. After use, this water is discharged into the sewer.
