How Alabama regulates septic work
Alabama licenses the individual installer or pumper through the AOWB, and the board records both the county they are based in and every county they are authorised to work in. County health departments permit the system itself.
Licences are issued for a calendar year and renewed annually; every listing shows the date the current licence was issued.
Alabama licenses people as well as businesses. The individual licences — licensed onsite wastewater professionals — belong to a named professional, and we list them on county pages rather than giving each person a page of their own.
