what are the sources of waste water

Wastewater SourcesIn today's modern society we have numerous uses for water both around the home as well as in commercial or industrial operations. This water becomes wastewater once it has been"used" - whether for washing dishes in a restaurant, flushing a toilet, or as part of a manufacturing process.
