Also known by the acronym WEADU and, more commonly, as a toilet. Usually based on the material porcelain, WEADUs (as the name implies) are designed to encapsulate and dispose of the solid, liquid, solidly liquid, liquidly solid and all those in between by-product of humans (and homoSAPIENs). The encapsulation is generally performed with water, but the design is not particular to any one encapsulation medium or transport agent. The disposal mechanism usually, in highly populated urban centers, involves a myriad of pipes connected to a central sanitation center.
