Some Adair County septic work now points to DHSS

Adair County's health department points certain onsite sewage permit questions to the Missouri Department of Health and Senior Services.

Septic work is one rural-property topic that deserves a paper trail.

In Adair County, an onsite wastewater permit is required for construction when the property is smaller than three acres, or when it is next to a public utility lake or Corps of Engineers property. The local health department also points permit seekers to the Missouri Department of Health and Senior Services because of an onsite program authority change.

That means the right office can depend on both the property and the current program setup. For a repair, replacement, new system, sale, refinance, or added-bedroom plan, ask which office has permit authority for the exact property.

Keep the answer with the project or closing file. Septic records can matter again years after the first call.
