Northern glacial country
Sand, gravel and variable glacial cover can support productive wells, but buried bedrock and casing depth change over short distances.
Often lower to moderateWisconsin does not publish one dependable statewide residential depth average. The WDF band uses the national complete-system range as a base; the property’s well report, casing requirement and transition from glacial material into bedrock determine where a real quote lands.
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.

Often lower to moderateSedimentary aquifers can be predictable regionally, while local well depth and water quality still need a record check.
Usually moderateShallow fractured carbonate rock can produce good yield, but vulnerability and casing details require careful construction.

WDF’s 2026 planning range is $3,000–$15,000 USD. Wisconsin does not publish one dependable statewide residential depth average. The WDF band uses the national complete-system range as a base; the property’s well report, casing requirement and transition from glacial material into bedrock determine where a real quote lands.
The reference point used here is no statewide average — check the dnr well report. 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.
