Setback Requirements
Definition
Setback requirements are regulatory minimums specifying how far a well must be located from sources of potential contamination. In Idaho, IDWR establishes minimum setback distances for various contamination sources. Common setback rules include minimum distances from septic tanks and drain fields (typically 50 to 100 feet), underground fuel storage tanks, animal feedlots or enclosures, irrigation channels, surface water bodies, roads, and property lines. Setback requirements must be evaluated and documented as part of the IDWR permit application process. On properties with constrained layouts — particularly urban lots, infill development, or sites with existing septic systems — setback compliance can significantly affect where the well can legally be located.

How Trident Drilling Company Uses It
Trident Drilling conducts setback analysis as part of the site evaluation process for every new well project. If setback constraints exist, Trident identifies compliant drilling locations before permit application and before any ground is broken.
