What this licence covers

Licensed for alternative systems
Onsite Wastewater Service Co holds Alternative sewage disposal system contracting (ADS). That covers the engineered systems used where a conventional drain field will not work — but not, on this specialty alone, conventional systems, which are CDS.
Class A contractor
Virginia's contractor classes cap the value of work a firm may take on: Class C is the smallest, Class A the largest. This is about contract size, not septic competence — the specialty codes above are what say they may touch a septic system.

What this listing does and does not tell you

Onsite Wastewater Service Co appears on Virginia’s septic licensing records as a licensed septic contractor, as published August 26, 2026. That is a statement by Virginia DPOR that the licence was held when the record was compiled.

The record puts the first certification at October 19, 2021 — 5 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.

Virginia DPOR does not publish phone numbers in these records, so there is no number to show. We also leave out the street address and email address the state publishes: at this scale a licence file is full of home addresses, and a tidy list of contact emails is a spam list rather than a directory.
