Wastewater is generated after the use of fresh water in a variety of applications,[1]: 1 and usually involves leaching, flushing, or washing away waste products and nutrients added to the water during these applications.[2] A more detailed definition for wastewater is "Used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff / storm water, and any sewer inflow or sewer infiltration".[3]: 175
In everyday usage, wastewater is commonly a synonym for sewage (also called sewerage, domestic wastewater, or municipal wastewater), which is wastewater that is produced by a community of people. It is typically transported through a sewer system.[3]: 175 : 10
As a generic term wastewater may also be used to describe water containing contaminants accumulated in other settings, such as:
- Industrial wastewater: waterborne waste generated from a variety of industrial processes, such as manufacturing operations, mineral extraction, power generation, or water and wastewater treatment.
- Cooling water, released with potential thermal pollution after use to condense steam or reduce machinery temperatures by conduction or evaporation
- Leachate, precipitation containing pollutants dissolved while percolating through ores, raw materials, products, or solid waste
- Return flow, carrying suspended soil, pesticide residues, or dissolved minerals and nutrients from irrigated cropland
- Surface runoff, the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
- Urban runoff, including water used for outdoor cleaning activity and landscape irrigation in densely populated areas created by urbanization
- Agricultural wastewater, generated from confined animal operations
