Sources of Wastewaters,

Wastewater is a broad, descriptive term of water that has been affected by anthropogenic influences, or simply put, water that has been used by man and then discarded. In the past, used and discarded water was referred to as ‘sewage’ water and meant water containing only sanitary wastes. Wastewater originates from different sources and contains contaminants of different quality and volume, and it includes liquids and waterborne solids from domestic, commercial, industrial and agriculture uses and any water whose quality has been degraded by human activity. There are two large categories of wastewater, the domestic and the industrial wastewater. Also, storm water is considered wastewater and is collected and treated together with domestic wastewater or separately.
