Homemade Septic Tank Design – Tips, Tricks, and Tutorials


Building a homemade septic tank can be a cost-effective and practical solution for those living in areas without access to a municipal sewer system. In this article, we will provide you with valuable tips, tricks, and tutorials on how to design and construct your own septic tank at home.

1. Understanding the Basics

Before diving into the design process, it’s crucial to have a solid understanding of how a septic tank works. A septic tank is an underground chamber that collects and treats wastewater from your home. It separates solid waste, allowing the liquid effluent to be discharged into a drain field.

2. Assessing Your Needs

The first step in designing a homemade septic tank is to assess your needs. Consider the size of your household, daily water usage, and the soil conditions in your area. This information will help determine the appropriate tank size and drainage system for your property.

3. Designing the Tank

When designing the tank, you need to consider factors such as tank material, dimensions, and inlet/outlet pipes. Concrete and fiberglass are common choices for tank materials due to their durability and longevity. The tank size should be determined based on the estimated wastewater volume.

4. Building the Tank

Once you have finalized the design, it’s time to start building the septic tank. Excavate the designated area, ensuring it is large enough to accommodate the tank and provide easy access for maintenance. Follow the design specifications carefully while constructing the tank.

5. Installing the Drain Field

The drain field is an essential component of a septic system. It consists of a network of perforated pipes buried in trenches filled with gravel. The effluent from the septic tank is distributed through these pipes, allowing it to percolate into the soil.

6. Maintenance and Care

Proper maintenance is crucial to ensure the longevity and efficiency of your homemade septic tank. Regularly inspect the tank for any signs of damage or leakage. Pump out the solid waste periodically to prevent clogging and overflowing.

7. Troubleshooting Common Issues

Even with proper maintenance, septic tank issues may arise. Common problems include clogs, foul odors, and slow drainage. Understanding the causes behind these issues and implementing appropriate solutions can help you resolve them effectively.

8. Safety Considerations

When working on a homemade septic tank, it’s essential to prioritize safety. Wear protective gear such as gloves and goggles while handling chemicals or working in confined spaces. Follow local regulations and guidelines to ensure compliance and prevent any potential health risks.


1. Can I build a septic tank without professional help?

Yes, with the right knowledge and guidance, building a septic tank can be done without professional help. However, it is crucial to thoroughly research and follow proper design and construction techniques.

2. How much does it cost to build a homemade septic tank?

The cost of building a homemade septic tank can vary depending on factors such as tank size, materials used, and local regulations. It is important to budget for excavation, materials, and any necessary permits.

3. Are there any legal requirements for homemade septic tanks?

Yes, there are legal requirements for septic tanks, even if they are homemade. Local authorities may have regulations regarding tank size, setback distances, and installation permits. It is essential to check with your local health department before starting the construction process.

4. How often should I pump out the septic tank?

The frequency of septic tank pumping depends on factors such as tank size, household size, and water usage. As a general guideline, it is recommended to pump out the tank every 3 to 5 years to prevent solids from accumulating and causing issues.

5. Can I use alternative materials for the septic tank?

While concrete and fiberglass are commonly used materials for septic tanks, alternative options such as plastic tanks may also be suitable. It’s important to ensure that the chosen material is durable, watertight, and resistant to corrosion.
