Who handles septic permits in Callaway County

Missouri registers the individual installer and records the counties they serve. Your local health authority permits the system itself, and in some counties runs its own additional requirements on top.

Licensed companies in neighbouring counties

A Missouri septic licence is valid statewide, so a company listed in an adjoining county can legally do the work in Callaway County.

Records as published August 26, 2026. A licence can lapse at any time — confirm with Missouri DHSS, or the state's own published registration data before hiring. Report a correction.
