This business is matched to a DHSS registered OWTS installer record — the credential Missouri requires of anyone installing an onsite sewage system for someone else (RSMo 701.031; 19 CSR 20-3.080(4)). It is a state registration, not a license, and it is not conditioned on a bond or on insurance. A registration runs thirty-six months from its own effective date, so Missouri has no single annual renewal cliff; where the roster shows one has run out, this listing says so and carries no verification badge. A registration is a filing, not an endorsement — ask for proof of insurance and references before hiring.

What this covers

Advanced OWTS Installer. Registered to install the systems the department lists as advanced OWTS, which only an advanced registrant may install. 19 CSR 20-3.080(4)(B) requires a basic registration in good standing first.

A Missouri registration is issued to a person, not to a company (19 CSR 20-3.080(4)), and it is valid statewide whatever counties the registrant lists beside it on the DHSS roster — RSMo 701.053.1 provides that a registration issued by a county “shall be considered a state registration and valid in all political subdivisions of the state”. It expires thirty-six months from its own effective date rather than on a date shared with everybody else’s, renews on a $90 processing fee and continuing education, and cannot be renewed at all more than forty-five days after it expires (19 CSR 20-3.080(7)).
