George Jennings (November 10, 1810 – April 17,1882) was an English sanitary engineer and plumber who invented the first public flush toilets.
A flush toilet 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. Flush toilets can be designed for sitting (in which case they are also called “Western” toilets) or for squatting, in the case of squat toilets. The opposite of a flush toilet is a dry toilet which uses no water for flushing.
Flush toilets usually incorporate an “S”, “U”, “J”, or “P” shaped bend (called a trap, such as P trap or S trap) that causes the water in the toilet bowl to collect and act as a seal against sewer gases (trapping the gases). Since flush toilets are typically not designed to handle waste on site, their drain pipes must be connected to waste conveyance and waste treatment systems. When a toilet is flushed, the wastewater flows into a septic tank or sewage system and from there to a sewage treatment plant.
A flush toilet may be colloquially called a lavatory, water closet (abbreviated W.C.), loo, comfort room (abbreviated C.R.), and many other names.
A flush toilet is different from a urinal, which is designed to handle only liquid waste; or from a bidet, which can be used for personal cleansing after toilet use.
