Answer:
Sewage and wastewater Edit
Sewage (or domestic wastewater) consists of wastewater discharged from residences and from commercial, institutional and public facilities that exist in the locality.[2]: 10 Sewage is a mixture of water (from the community's water supply), human excreta (feces and urine), used water from bathrooms, food preparation wastes, laundry wastewater, and other waste products of normal living.
Sewage from municipalities contains wastewater from commercial activities and institutions, e.g. wastewater discharged from restaurants, laundries, hospitals, schools, prisons, offices, stores and establishments serving the local area of larger communities.[2]: 21
Sewage can be distinguished into "untreated sewage" (also called "raw sewage") and "treated sewage" (also called "effluent" from a sewage treatment plant).
The term "sewage" is nowadays often used interchangeably with "wastewater" - implying "municipal wastewater" - in many textbooks, policy documents and the literature.[2][5][6] To be precise, wastewater is a broader term, because it refers to any water after it has been used in a variety of applications.[5]: 1 Thus it may also refer to “industrial wastewater”, agricultural wastewater and other flows that are not related to household activities.
Blackwater Edit
This section is an excerpt from Blackwater (waste).[edit]
Blackwater in a sanitation context denotes wastewater from toilets, which likely contains pathogens which may spread by the fecal–oral route. Blackwater can contain feces, urine, water and toilet paper from flush toilets. Blackwater is distinguished from greywater, which comes from sinks, baths, washing machines, and other kitchen appliances apart from toilets. Greywater results from washing food, clothing, dishes, as well as from showering or bathing.[7]
Blackwater and greywater are separated in "ecological buildings", such as autonomous buildings. Recreational vehicles often have separate holding tanks for greywater from showers and sinks, and blackwater from the toilet.
Greywater Edit
This section is an excerpt from Greywater.[edit]
Greywater (or grey water, sullage, also spelled gray water in the United States) refers to domestic wastewater generated in households or office buildings from streams without fecal contamination, i.e., all streams except for the wastewater from toilets. Sources of greywater include sinks, showers, baths, washing machines or dishwashers. As greywater contains fewer pathogens than domestic wastewater, it is generally safer to handle and easier to treat and reuse onsite for toilet flushing, landscape or crop irrigation, and other non-potable uses. Greywater may still have some pathogen content from laundering soiled clothing or cleaning the anal area in the shower or bath.
The application of greywater reuse in urban water systems provides substantial benefits for both the water supply subsystem, by reducing the demand for fresh clean water, and the wastewater subsystems by reducing the amount of wastewater required to be conveyed and treated.[8] Treated greywater has many uses, such as toilet flushing or irrigation.[9]
