When you need a permit
You need a permit for a new installation or a major repair. Senate Bill 446 established Missouri statutes 701.025 through 701.059, which set the standards and procedures for construction and repair of on-site sewage systems, complaint investigation, installer registration and training, and soil evaluation.
The permit process
Buy the Missouri DHSS On-Site Sewage Disposal System Construction Permit
Have a soil morphology evaluation performed by a registered soil scientist
Submit the permit, the soil report, and the completed application packet
BCHD reviews and issues the construction permit
Install the system
BCHD performs a final site inspection
What stops a permit
A permit will not be issued if the state permit was not purchased, if the soils report shows unsuitable soil, if the application packet is incomplete or never submitted, or if the proposed system does not meet the regulations.
Soil morphology
Only a soil scientist registered with Missouri DHSS may perform a soil morphology evaluation for the design and construction of an on-site sewage system. The department keeps a list of registered installers and qualified soil evaluators.
What we do and do not do
Butler County Health Department does not design septic systems. Staff do offer technical assistance and advice to anyone who asks for it.
Maintaining your system
A well-maintained septic system lasts decades. A neglected one fails and costs thousands.
How often should I pump?
Every 3 to 5 years for most households, depending on tank size and household size.
What should never go down the drain?
Grease, wipes (even “flushable”), paint, solvents, and medications.
How do I protect the drainfield?
Keep vehicles off it, direct roof water away, and plant only grass above it.
What are the warning signs of failure?
Slow drains, sewage odor, wet spots over the drainfield, and backups after rain.
