Floating toilet

A floating toilet is essentially a toilet on a platform built above or floating on the water. Instead of excreta going into the ground they are collected in a tank or barrel. To reduce the amount of excreta that needs to hauled to shore, many use urine diversion. The floating toilet was developed for residents without quick access to land or connection to a sewer systems. It is also used in areas subjected to prolonged flooding. The need for this type of toilet is high in areas like Cambodia.
