What this licence covers

Certified to install any onsite wastewater system
The highest grade held by anyone at Quan Underground LLC is Grade Level IV, which permits them to install any onsite wastewater system: conventional gravity systems, and also dual pumps or siphons, low-pressure and drip dispersal, groundwater lowering, pretreatment and reuse systems, and systems with no daily flow limit.
2 certified people on the board's list
North Carolina certifies the installer personally rather than the firm, so a company's capability is the sum of its certified staff. Quan Underground LLC has 2 across 2 grade levels (Grade IV, Grade II).

What this listing does and does not tell you

Quan Underground LLC appears on North Carolina’s septic licensing records as a certified septic installer, as published August 21, 2026. That is a statement by NC OWCICB that the licence was held when the record was compiled.

The record puts the first certification at November 3, 2023 — 3 years ago. Longevity is not a measure of quality, but it is a fact the state publishes and it is hard to fake.

It is not a rating, a review, an endorsement or a guarantee of insurance, price or workmanship — and licences lapse. Nothing on this page comes from the company itself, and no company pays to be here.

To confirm the licence is current today, check with the certification board, or your county environmental health office. Step by step →
