Cesspit

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).[1] 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.[1] 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).
