Central and western glacial country
Layers of sand, gravel and clay can change casing and productive depth across short distances.
Often moderate, locally variableMinnesota’s glacial deposits, southeast karst and northeast bedrock do not support one useful statewide residential depth average. This WDF complete-system band is a starting point; casing, well sealing, pump scope and deeper rock drilling can move a quote outside it.
The range is calculated from government well records or depth guidance and the ground conditions commonly encountered in the area. It is not a published government price and it cannot predict whether a specific bore will be dry, unusually deep or difficult to reach.
Ask every bidder for one complete-system total. It should identify drilling, casing, grouting, pump, pressure tank, electrical work, permit or filing charges, water testing and restoration separately.
Layers of sand, gravel and clay can change casing and productive depth across short distances.
Often moderate, locally variableFractured carbonate rock can be productive but vulnerable to surface contamination, making siting and testing especially important.
Water-quality planning priorityShallow soil, hard rock and remote access can raise drilling and mobilization costs.
Higher rock and access riskUse a Minnesota-licensed well contractor and verify the current credential with the Department of Health before signing.

WDF’s 2026 planning range is $4,000–$16,000 USD. Minnesota’s glacial deposits, southeast karst and northeast bedrock do not support one useful statewide residential depth average. This WDF complete-system band is a starting point; casing, well sealing, pump scope and deeper rock drilling can move a quote outside it.
The reference point used here is no single statewide depth — use the minnesota well index. A nearby completion record is more useful than a broad average, and only drilling confirms the final depth and yield.

Compare drilling, casing, grout, pump, pressure tank, electrical work, permit or filing fees, yield testing, disinfection, laboratory testing, restoration, over-depth pricing and dry-hole terms on separate lines.
Depth, licensing and permit statements are checked against government records. Cost figures are WDF planning estimates derived from those records and the published 2026 cost model.
