Inspection process
- 1
Pre-backfill inspection
Planning Department inspects the installed system after installation but before backfilling, to confirm it was built per approved plans and county wastewater regulation standards.
Tips
- Authorization to Construct expires two years from issuance if installation/inspection isn't completed; a renewal may be requested at least 30 days before expiration if plans are unchanged.
- Albany County does NOT permit water wells — those go through the Wyoming State Engineer's Office (307-777-6163), not the county.
