Licensed to Perform
Work authorized by this license, per the South Carolina Department of Environmental Services. This reflects the license's scope, not a list of services the business advertises.
What this OSWW Installer Tier 2 covers
South Carolina licenses onsite wastewater installers in three tiers under S.C. Reg. 61-56, administered by the Department of Environmental Services. The tiers are cumulative and the boundary between them is real: a Tier 1 licence does not permit repairs to an existing system at all. Licences renew annually. Continuing education runs on a two-year cycle — eight hours at Tier 1, twelve at Tier 2, eighteen at Tier 3 — a requirement that took effect on 1 July 2025. Tier 3 installers must also carry a bond and insurance under §61-56.703.
Tier 2 covers everything Tier 1 does and adds pumps, grease traps, curtain drains, elevated infiltration and mounded systems, and all commercial, large and community systems. Unlike Tier 1, it authorises repairs to existing systems.
Checking it yourself: SCDES publishes the licensed installer and pumper/hauler roster. The register lists only active licences, so a firm's presence here means the licence was current when the register was last read.
Based on S.C. Reg. 61-56; SCDES OSWW licensing guidance.
