People make hand dug wells since history. They dig until they find water. A hand dug well has normally a diameter of 0.8 up to 1.5 metre and varies in depth, depending on how deep water is found. When using a ventilator for fresh air during digging, it becomes even possible to dig up to 30 meter or more. A hand dug well can be made in hard soils as well as in soft soils. The soil structure and water level determines how to support the walls.
