Septic installation and replacement in Christian County, Missouri
Christian County adopted its own onsite wastewater ordinance in 1992 and last revised its construction standards in October 2015, and it is one of the counties that licenses installers itself. Anyone installing for hire here needs a Christian County license on top of their state registration, and that license expires every two years with a short renewal exam. A homeowner doing the work on their own system does not need that license, but they do still need the permit. A rural build here can involve three different agencies: the health department for septic, county building regulations for the structure, and the Department of Natural Resources for a well.
Who issues a septic permit in Christian County, MO?
The Christian County Health Department, Environmental. That is the office to call before anything else, because in Missouri the permitting authority is not the same kind of agency in every county, and assuming it is the health department wastes a week in the counties where it is not.

Missouri lets a county adopt standards more restrictive than the state's, so a requirement here is not evidence of the same requirement one county over.

What is the ground like in Christian County?
Ozark karst, and it is the controlling fact for septic design here. Christian County sits south of the Missouri River on the Springfield Plateau, where thin residual soil sits directly on fractured, cavernous limestone. Effluent that reaches bedrock in this ground is not treated by soil on the way: it enters groundwater through solution channels. That is why the separation between the bottom of a system and bedrock matters more here than percolation rate alone.
That matters because the soil decides the system. A standard system needs at least one foot between the trench bottom and the limiting layer or seasonal high water table, rising to four feet to groundwater or bedrock in highly permeable soils and in cherty clay soils in areas of severe geological limitations, and a percolation rate slower than sixty minutes per inch pulls a registered engineer onto the design.
The soil evaluation is what settles it for your particular lot.

Which towns does this cover?
Christian County has Ozark as its county seat. Places served include Ozark, Nixa, Clever, Sparta, Billings, Fremont Hills, Highlandville, Saddlebrooke, Chadwick, Spokane. Anywhere in the county not on a public sewer is on a system this page applies to.
Who is allowed to do the work here?
An installer registered with the Missouri Department of Health and Senior Services. That is a state requirement rather than a county one, and it applies wherever you are. Some counties add their own licensing on top of it, which is one more reason to ask the permitting authority what they require before you sign anything.
How to check an installer's registration takes one phone call.

What we could not confirm for this county
Whether the county wastewater ordinance reaches inside incorporated city limits, or applies only to unincorporated areas, was not established, and which parts of Nixa and Ozark are on public sewer was not mapped. The health department publishes a current fee schedule, and fees change, so no figure is repeated here. Confirm both with the department.
