When you need this permit
- Required for construction, installation, or modification of any small wastewater (septic) system
- Systems must be installed by a licensed installer, OR the property owner may install their own system under guidance of the county's Small Wastewater Resolution and the Wastewater Engineer
- Process: (1) obtain the Small Wastewater Permit Application from Planning & Zoning; (2) conduct groundwater observation cut and percolation tests; (3) submit the septic permit application with design layout to Planning & Zoning; (4) obtain the county-issued Small Wastewater Permit to Construct; (5) install per approved design; (6) Planning & Zoning inspects the system BEFORE backfilling; (7) obtain the Small Wastewater Facility Permit with permission to backfill
- The county can require excavation/removal/rebuild of a non-compliant system found during inspection
- Issuance of a permit to construct does not relieve the permittee of responsibility for proper design, construction, operation, and maintenance

Inspection process
- 1
Pre-Backfill Inspection
Planning & Zoning Office inspects the installed system BEFORE backfilling occurs; a non-compliant system can be required to be unearthed, removed, or rebuilt
Tips
- This IS a genuine county-issued construction-related permit even though the county has no general building permit — septic/small wastewater is administered locally by Uinta County Planning & Zoning, not by the state.
- Do not backfill a septic system before the county inspection — the county requires a BEFORE-backfill inspection and can require you to unearth a non-compliant system.
