Dual Flush Toilet

The dual-flush toilet was designed as a way to reduce water use and improve sanitation.

This type of fixture uses two buttons or handles – one for flushing liquid waste, which can include things like urine or feces; the other is larger and intended specifically towards solid digestion matter such as excrement (or “crap”).

By combining these differing requirements into one system you are able flush everything without having too much wasted while still being able take care your wastes properly due its wide range capabilities! (wikipedia.org)
