A cesspit, or cesspool is a pit, conservancy tank, or covered cistern, which can be used for sewage or refuse. Traditionally, it was a deep cylindrical chamber dug into the earth, having approximate dimensions of 1 meter diameter and 2-3 meters depth. Their appearance was similar to that of a hand-dug water well.
