What is the longevity of a leach pit toilet?
In a leach pit toilet, two pits are supposed to be constructed. When the first pit is in use, the other pit is closed. A pit having 4ft. depth and 3 ft. diameter can get filled up in about 4-5 years if used by a family of 6-8 persons. Once this pit is filled up, the other pit is opened and the filled pit is closed. Within 15-18 months, the excreta gets totally decomposed and become a good bio-fertilizer. There is neither any bad odour nor any pathogen in the fertilizer (decomposed excreta). This can be easily used in the fields. Even if the number of persons using the toilet increases, the pit having a size of 4 ft. deep and 4 ft diameter is sufficient to meet the requirement.
