What this listing does and does not tell you
John Walker appears on Missouri’s septic licensing records as a registered owts installer, as published August 26, 2026. That is a statement by Missouri DHSS that the licence was held when the record was compiled.
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.
Missouri DHSS 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.
