Cesspool

{ Cesspit, cesspool and soak pit in some contexts are terms with various meanings: they are used to describe either an underground holding tank (sealed at the bottom) or a soak pit (not sealed at the bottom). A cesspit can be used for the temporary collection and storage of feces, excreta, or fecal sludge as part of an on-site sanitation system and has some similarities with septic tanks or with soak pits. Traditionally, it was a deep cylindrical chamber dug into the ground, having approximate dimensions of 1 metre (3.3 ft) diameter and 2–3 metres (6.6–9.8 ft) depth. Its appearance was similar to that of a hand-dug water well. The pit can be lined with bricks or concrete, covered with a slab, and needs to be emptied frequently when in use as an underground holding tank. In other cases (if soil and groundwater conditions allow), it is not constructed watertight, to allow liquid to leach out (similar to a pit latrine or to a soak pit). {
