Well Drilling Permit

Definition

A well drilling permit is the official approval from the Idaho Department of Water Resources (IDWR) that authorizes a driller to construct a new well, deepen an existing well, or perform other regulated groundwater work on a specific property. The permit application includes the property’s legal description, the intended use of the well (domestic, commercial, agricultural, etc.), the driller’s license number, and the proposed construction method. IDWR reviews the application to ensure the proposed well complies with setback requirements, does not conflict with existing water rights, and meets state construction standards. The permit must be on-site during drilling and is the legal authorization that allows work to begin.

Frequently Asked Questions

Why Well Drilling Permit Matters

No well drilling in Idaho is legally permitted without this authorization. Property owners who discover their existing well was drilled without a permit face regulatory exposure and can have difficulty selling the property or obtaining financing. For new construction projects, permit timeline must be factored into the project schedule — delays in permit issuance can delay construction starts.

How Trident Drilling Company Uses It

Trident Drilling obtains all required IDWR permits on behalf of clients before any drilling begins. Permit applications are submitted as early as possible in the project planning process to account for IDWR processing times and to avoid construction schedule delays.
