How many feet is the diameter of a dug well?

The diameter of a dug well typically falls within the range of 3 to 20 feet. Dug wells are excavated by hand or with machinery, and their design often prioritizes wider diameters to provide easier access for maintenance and cleaning. A well that is too narrow may not only be difficult to access but could also limit the amount of water available. In contrast, larger diameters can facilitate better water flow and make it easier to install and maintain any necessary equipment.

The other ranges presented do not accurately represent the standard diameters for dug wells. A diameter of 1 to 3 feet is generally too small for practical dug well construction, while 25 to 35 feet and 35 to 40 feet indicate diameters that are much larger than what is typically constructed for dug wells and are instead more characteristic of drilled wells or more specialized structures. Therefore, the choice reflecting a diameter of 3 to 20 feet is the most appropriate and accurate portrayal of dug wells.
