A basic pitwith drop hole and lid.The excreta lies here until it gets full,
and then sealed Design Pit latrines are designed for the onsite disposal. They consist of a
concrete squatting plate or riser, which is placed over an earthen pit.
Pit diameter between - 1 and 1.5 m. Pit depth- Minimum3mdeep. The top (0.5 m of the pit) always requires lining. In loose soil, the entire pit should be lined in order to prevent collapse. The urine and water content of faeces is normally designed to be absorbed into the soil (otherwise the pit will fill up faster). One unit can serve one or several households. These are easy to operate and maintain. The design life varies, depending on the number of users (several years to 10 years or more)
