Missouri septic rules
Septic pumping rules in Missouri.
We did not find a statewide license for septic pumpers in Missouri. Counties and cities may still require one. Below: who regulates, what pumpers have to keep, and where to find the official forms. Checked against official sources on October 8, 2026.
The rules
What a pumper in Missouri should know.
A guide, not legal advice. Counties and local health departments can add their own rules on top of the state's, so check with the county where the system is.
- Who regulates septic systemsState and local
Missouri Department of Health and Senior Services (DHSS), Onsite Wastewater Treatment Program. DHSS sets minimum state construction standards and registers onsite professionals, while in most counties the local health department issues construction permits (elsewhere a sewer district, building department or planning and zoning office), and local ordinances can be more restrictive.
The state program- Pumper and hauler licensingNo state license found
DHSS registers or licenses installers, inspectors/evaluators and soil professionals who complete its courses and renew every three years with an ID card, but no state license or registration for septic tank pumpers or septage haulers was found on the DHSS pages read. Local requirements may apply.
Licensing details- Where septage can go
Not confirmed from an official source. Ask the state program linked above, or your county health department.
- Records and reports
Not confirmed from an official source. Ask the state program linked above, or your county health department.
- Inspections
Individuals must be licensed by DHSS to perform private assessments of existing systems for real estate transactions. DHSS distinguishes an inspection (full assessment including a hydraulic test of the soil treatment system) from an evaluation (no hydraulic test), and copies of reports are provided to the DHSS Onsite program. DHSS says local public health agencies mostly no longer inspect existing systems for real estate transfers. Requirements for inspectors/evaluators are in 19 CSR 20-3.070. No state rule requiring an inspection at sale was found.
Inspection rules- The rule book
19 CSR 20-3.015 (operation of on-site sewage systems), 19 CSR 20-3.060 (Minimum Construction Standards for On-Site Sewage Disposal Systems), 19 CSR 20-3.070 (inspectors/evaluators), 19 CSR 20-3.080

Questions
Do I need a license to pump septic tanks in Missouri?
We did not find a statewide license for septic pumpers in Missouri. Counties and cities may still require one. DHSS registers or licenses installers, inspectors/evaluators and soil professionals who complete its courses and renew every three years with an ID card, but no state license or registration for septic tank pumpers or septage haulers was found on the DHSS pages read. Local requirements may apply.
Where do I get Missouri septic forms?
From the state's own pages, linked on this page. Many counties and local health departments use their own forms on top of the state's, so check with the county where the system is too.
Does PortaPro come with Missouri forms built in?
No. Forms change, and counties use their own, so PortaPro doesn't ship copies. You upload the current PDF from your county or state once, place the fields on it, and PortaPro fills it from each job: customer, site, tank, gallons pumped and technician. When the agency updates its form, you upload the new one.
How current is this page?
We read the official sources listed at the bottom on October 8, 2026. Rules and forms change, so treat this as a starting point and confirm with the agency before you rely on it. This is not legal advice.
