What this listing does and does not tell you
Psi appears on Missouri’s septic licensing records as a registered onsite soil evaluator, 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.
To confirm the licence is current today, check with Missouri DHSS, or the state's own published registration data. Step by step →
