The hole for most home wells is usually drilled at a diameter between 6 to 12 inches. The drilling method will depend on the geologic formations, the required water yield and the type of drilling equipment used.

Drill rigs are expensive (often up to $500,000) and their use requires considerable skill. All wells require casing to protect them from possible contaminants at or near the ground surface. Casing may not be needed for the portion drilled into bedrock.

Generally speaking, most residential wells in our service area obtain water in the bedrock from an open hole drilled into the bedrock. Water comes into the well from fractures in the bedrock.
