The ground in Mulvane
Mulvane sits east of the Arkansas River and straddles the Sedgwick–Sumner county line. West toward the river the soils are sandier bottomland; east and south, up on the farm ground, they get siltier and heavier with clay, and a field there takes water more slowly.
That mix shows up in the systems we see: septic tanks with lateral fields on the lighter soils, and lagoons on the heavier ground where acreage allows it. Both start with a septic tank, and both need that tank pumped.
Permits and rules
Which office permits a system depends on which side of the county line the property is on. North of the line it’s Sedgwick County’s MABCD; south of it, Sumner County. Either way, repair and replacement work needs a permit, and the installer should know the county’s standards before digging.

Mulvane septic questions
Questions from Mulvane.
I used Mulvane Septic. Is that the same company?
Mulvane Septic was combined with Sunflower Septic and Mosley Septic to form Mosley Services. The number to call now is (316) 777-4000.
My Mulvane property has a lagoon. Does it still have a septic tank?
Usually, yes. Sedgwick County’s lagoon standards call for a 1,000-gallon septic tank ahead of the lagoon, with risers to grade. That tank catches the solids and needs pumping like any other, or sludge ends up in the lagoon.
Who issues septic permits in Mulvane?
It depends on the county. Sedgwick County properties go through MABCD; properties on the Sumner County side go through Sumner County. Call the county before any repair, or let a licensed installer handle the permit.
