A flush toilet (also known as a flushing toilet, water closet (WC) – see also Toilet (names)) is a toilet that disposes of human excreta (urine and feces) by using water to flush it through a drainpipe to another location for disposal, thus maintaining a separation between humans and their excreta.

In other words: "Toilets are sanitation facilities at the user interface that allow the safe and convenient urination and defecation".
Open defecation, the practice of defecating outside without using a toilet of any kind, is still widespread in some developing countries, for example in India.

Open defecation

These toilets are usually, but not always, self-contained and movable.

Sanitation

In other words: "Toilets are sanitation facilities at the user interface that allow the safe and convenient urination and defecation".
Providing sanitation to people requires attention to the entire system, not just focusing on technical aspects such as the toilet, fecal sludge management or the wastewater treatment plant.

Pit latrine

pit toiletpit latrineslatrine
Many poor households in developing countries use very basic, and often unhygienic toilets, for example simple pit latrines and bucket toilets which are usually placed in outhouses. For example, from simple to more complex: a bucket toilet (honey bucket), a tree bog or arborloo (two simple systems for converting excrement to direct fertiliser for trees), a pit latrine (a deep hole in the ground), a vault toilet (which keeps all the waste underground until it is pumped out), a container-based toilet, a composting toilet (which mixes excreta with carbon-rich materials for faster decomposition), a urine-diverting dry toilet (which keeps urine separate from feces), and incinerating and freezing toilets.
A pit latrine, also known as pit toilet or long drop, is a type of toilet that collects human feces in a hole in the ground.

It includes household waste liquid from toilets, baths, showers, kitchens, and sinks draining into sewers.

Urination

Sustainable Development Goals

2030 Agenda for Sustainable DevelopmentSustainable Development GoalSDGs
The Sustainable Development Goal Number 6 calls for "adequate and equitable sanitation and hygiene for all and end open defecation by 2030".
Safe drinking water and hygienic toilets protect people from disease and enable societies to be more productive economically.

World Toilet Day

Toilets are important because access to a safe functioning toilet has a positive impact on public health, human dignity, and personal safety, especially for women.

Urine diversion

The diverted urineUrine separation
Urine diversion toilets have two compartments, one for urine and one for feces.
Urine diversion, also called urine separation or source separation, refers to the separate collection of human urine and feces at the point of their production, i.e. at the toilet or urinal.

Urine-diverting dry toilet

For example, from simple to more complex: a bucket toilet (honey bucket), a tree bog or arborloo (two simple systems for converting excrement to direct fertiliser for trees), a pit latrine (a deep hole in the ground), a vault toilet (which keeps all the waste underground until it is pumped out), a container-based toilet, a composting toilet (which mixes excreta with carbon-rich materials for faster decomposition), a urine-diverting dry toilet (which keeps urine separate from feces), and incinerating and freezing toilets.
This dry excreta management system (or "dry sanitation" system) is an alternative to pit latrines and flush toilets, especially where water is scarce, a connection to a sewer system and centralized wastewater treatment plant is not feasible or desired, fertilizer and soil conditioner are needed for agriculture, or groundwater pollution should be minimized.

Fecal–oral route

fecal-oral routefecal-oralfaecal-oral route
Diseases transmitted via the fecal-oral route or via water, such as cholera and diarrhea, can be spread by open defecation.
The F-diagram can be used to show how proper sanitation (in particular toilets, hygiene, handwashing) can act as an effective barrier to stop transmission of diseases via fecal–oral pathways.

Vacuum sewer

Reuse of human waste

It can be linked to systems which reuse excreta as a fertilizer.
Reuse of human wasteis the final step of the sanitation chain which starts with collection of human waste (by use of toilets) and continues with transport and treatment all the way to either disposal or reuse.
