Interpretations and Explanations

There are three common types of modern chemical toilets. In the first type, a cylindrical bucket fitted with a plastic lid and seat holds about 50 mm depth of chemical fluid and usually has a capacity of 20-30 litres. The two-tank system includes a flushing-liquid reservoir of fresh water where a deodorizing chemical is pumped manually to the rim of the pan and a waste-storage tank for discharge. The single tank system is fitted with a flushing pan. A manual or electrically operated pump recirculates oil, drawing it from the base of the tank through a filter and discharging it around the rim of the pan. The pan has a counter-balanced flap so that the contents cannot be seen (WHO 1992).A simple chemical toilet is sometimes found in homes where indoor plumbing is not available. An even simpler chemical toilet consists of a seat on a container or bucket of water, with a solution of chemicals used to disinfect and deodorize (World Plumbing Council Working Group 2008).
