Limestone drainage systems - ScienceDirect

Dec 01, 1975  The pit has an estimated storage capacity of 5,850 m3 and may be expected to overtop on one or two days a year. Such overtopping of the pit is a function of flow duration at that point which is in turn dependent on soil moisture content of the upper catchment, rainfall duration and rainfall intensity.

Limestone - Wikipedia

Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more ...

Pit latrine - Wikipedia

A pit latrine, also known as pit toilet, is a type of toilet that collects human feces in a hole in the ground. Urine and feces enter the pit through a drop hole in the floor, which might be connected to a toilet seat or squatting pan for user comfort. Pit latrines can be built to function without water or they can have a water seal (pour-flush pit latrine).
