Abstract
An improved sanitary water closet wherein the soil pipe leading to the sludge tank, passes through a flushing container and is formed inside the latter with a bend provided with grid means arranged to allow passage through of liquid into the container and further to a septic tank, but to divert solid material to the sludge tank. Because of the separation of liquid and solid products, the sludge product obtained in the sludge tank contains very little moisture and is therefore easily biologically degradable.
