Plan a residential well in Connecticut
WDF planning range centered on the reviewed Connecticut well-record depth average. The public record set spans very shallow to very deep wells, so nearby logs and multiple complete quotes matter more than the average alone.

How the estimate works
Depth is only the first number
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.

Why Connecticut quotes vary by area
Valleys and glacial deposits
Local sand and gravel can reduce resistance, but aquifer extent is site-specific.
Potentially lowerCoastal properties
Setbacks, saltwater risk and limited access require careful siting and water testing.
Extra planning riskVerify the people doing the work
Connecticut DCP licenses well drillers and related trades. Verify the current credential for the contractor and individual doing the regulated work.

Compare the same scope—not just the headline price
- Licence and insurance: match the name on the proposal to the current public record.
- Depth and per-foot terms: record the included depth, overage rate and dry-hole terms.
- Complete system: separate drilling, casing, grout, pump, tank, wiring, permit, test and restoration.
- Water and workmanship: ask about yield testing, disinfection, laboratory testing and written warranties.
