tell me. The soil is sandy, digging a cesspool. Water appeared two meters away. Is it high eel? is it possible to make a brick cesspool with such depth?
It is not advisable, this is a high level of standing groundwater, there is a high risk that your brick wall will fall down. Concrete walls and shallower depth will be more reliable, while its capacity will decrease, and it will be necessary to clean it more often. Try to find another place for her. In a simple folk way, as people digging wells do, they are looking for a suitable place, by the same principle, look for a place not suitable for a well, maybe there the level will be lower.
