prefabricated, toilet direct way, and into the fecal pipe connection, also can use water sealed toilet, no longer install near dung pipe.
Into the fecal pipe: plastic, cast iron, cement pipes are available, the inner wall smooth, prevent feces, the inner diameter of 10cm, length of 30-50cm.

Three cell pool: brick with cement powder, wall or cement, cast-in-place, prefabricated can be, in order to "eye" font as the main type, if subject to topographic restrictions, "goods", "font", "Ding" type pendulum can also be. The volume reached storage stool for 2 months is appropriate. The effective depth of the three cell shall be no less than 1 cm, and the volume ratio between 1 and 3 shall be 2:1:3.
