Licensed to Perform
Work authorized by this license, per the North Carolina Onsite Wastewater Contractors and Inspectors Certification Board. This reflects the license's scope, not a list of services the business advertises.
What this Onsite Wastewater Installer Grade Level IV; Point of Sale Inspector covers
NCOWCICB certifies the people who install and inspect onsite wastewater systems in North Carolina. Certification is graded by the complexity of system a holder may install, and continuing education is required in each calendar year — three hours at Grade Level II, six at Grade Level IV and six for a Point of Sale Inspector. The grade structure changed on 1 January 2025: existing Grade I holders moved to Grade II and Grade III holders to Grade IV, leaving only those two installer grades. The Board does not regulate pumping. A septage pumping business needs a separate permit from NC DEQ.
Grade Level IV covers the full range of system types, from conventional gravity through low pressure, drip dispersal, pretreatment and reuse, and flows above 1,500 gallons per day. The Point of Sale Inspector certification alongside it authorises inspection of an existing system for a real estate transaction — a distinct credential from installation.
Checking it yourself: NCOWCICB publishes its certification list. Check that the grade covers the system you are having installed, not just that a certification exists.
Based on NCOWCICB certification guidance and FAQ; SB 166 (eff. 2025-01-01).
