Do You Need a Permit to Install a Septic Tank – Guide

As an industry leader in septic services in Jefferson City, Missouri, our team at Superior Sewer Solutions often gets the question, “Do you need a permit to install a septic tank?” The short answer is almost always yes. The longer answer involves understanding state regulations, local rules, and the permit process itself.

We’d like to break it down in simple terms, so you’ll know exactly what to expect.

Why Regulations Require Septic Tank Permits

Installing a septic tank involves much more than digging a hole and dropping in the hardware. Septic systems handle wastewater that can rapidly contaminate drinking water and streams. The Missouri Department of Health and Senior Services (DHSS) requires a septic tank permit for virtually every new installation. 

In addition to protecting public safety, the permit process ensures that your system meets environmental compliance regulations, operates efficiently, and serves your household for years to come.

Understanding Septic Permit Requirements

In Missouri, the DHSS oversees statewide septic regulations, but the permit application process is usually handled by your county’s local health department. Regardless of where you live in the state, these are the basic steps involved when you need a permit to install a septic tank: 

Determine Whether You Need a Permit   

The only notable exception to the permit requirement is for single-family homes on parcels of 10 acres or more that meet very specific criteria. Even then, you’ll need written confirmation from your local authority. 

Contact the Local Health Department 

Each county may have additional local regulations on top of state requirements. It’s important to reach out to your county health department early to understand specific rules and avoid delays. 

Schedule a Site and Soil Evaluation 

A certified evaluator or professional engineer will conduct soil tests to determine your property’s suitability. This test measures how quickly water drains through your soil, impacting which septic system types, if any, you may install. 

Design the System 

A licensed installer or engineer designs your septic system based on your soil test results, lot size, and household size. The design will specify tank size, drainfield location, and system type. 

Submit Your Permit Application 

Once you’ve completed the site evaluation and system design process, you’ll submit everything along with your permit application process paperwork, fees, and property information to your county’s permitting office. 

Complete the Installation and Schedule Inspections 

Your licensed installer will handle the installation according to approved plans, followed by required inspections from the county. Inspectors verify proper installation and ensure complete environmental compliance before providing wastewater system approval. 

Planning Permission and HOA Rules: Don’t Overlook These Details

Aside from county regulations, you may need a permit to install a septic tank from a local planning permission if your property is within city limits or under certain zoning laws.  

Additionally, if your property is part of a homeowners’ association (HOA), you’ll want to review its covenants, conditions, and restrictions. Some HOAs require pre-approval for any septic installation and may impose aesthetic or system type limitations.

Common Types of Septic Systems Approved Locally

Common septic system types installed in Missouri include: 

• Conventional systems: Ideal for properties with good soil and adequate space  

• Mound systems: Used when soil conditions or high water tables require elevating the drainfield  

• Aerobic treatment units (ATUs): These advanced systems inject oxygen to break down waste more effectively, often used in smaller lots or challenging soils  

• Chamber, sand filter, or gravelless systems: Solutions for specific site conditions, designed to maximize treatment and space efficiency
