Work authorized by this license, per the Alabama Onsite Wastewater Board. This reflects the license's scope, not a list of services the business advertises.
What this Adv Installer (Lv 1) And Installer covers
The Alabama Onsite Wastewater Board licenses installers and pumpers under Ala. Code § 34-21A. Installer licences are tiered by system flow and complexity, and the tiers must be earned in order — a basic licence first, then Advanced Level I, then Advanced Level II, each with a time-in-grade and completed-systems requirement. Every licensee must be bonded for the work the licence covers: a minimum of $15,000 for a basic installer, pumper, portable toilet or manufacturer licence, and $30,000 for either advanced level. A lapsed bond suspends the licence immediately.
Advanced Level I adds small-flow systems up to 1,800 gallons per day, mound systems, simplex pumps with time dosing, and on-demand duplex pumps including single-family systems with secondary treatment. Anything above 1,800 gallons per day requires Advanced Level II.
Checking it yourself: The Board runs a public licence search. Because the flow thresholds are hard boundaries in Alabama, confirm the level covers your system's design flow before work starts.
Based on Ala. Code § 34-21A-12 and § 34-21A-16; AOWB Administrative Code 628-X.
