What is the maximum diameter for drilled wells?

• A. 2-6 inches
• B. 4-12 inches
• C. 15-20 inches
• D. 20-30 inches

Answer: (B)

The maximum diameter for drilled wells typically falls in the range of 4 to 12 inches. This size range is most practical for ensuring the structural integrity of the well while allowing for efficient water extraction. Drilled wells are generally designed to optimally balance flow capacity with the stability of the well casing and the surrounding geology. Wells with a diameter larger than 12 inches may encounter issues related to construction, maintenance, and hydraulic performance, as larger diameters are less common and could lead to increased costs and complexities. Smaller diameters, while they can be drilled, may not allow for sufficient water flow, particularly in areas where higher yields are necessary. Therefore, the selected diameter range of 4 to 12 inches aligns with typical engineering and environmental safety standards for drilled wells, making it the correct and accepted range for this type of water well construction.
