Introduction to Building a Septic Tank and Soakaway
In rural and semi-urban areas, where access to municipal sewage systems is limited or non-existent, septic tanks and soakaways play a crucial role in waste management. These systems are designed to treat and dispose of wastewater from households, ensuring that harmful contaminants are effectively managed and do not pose a threat to the environment or public health. Understanding how to build a septic tank and soakaway is essential for homeowners looking to maintain their property and comply with local regulations.
A septic tank is a watertight container, typically made of concrete, fiberglass, or plastic, that collects and treats wastewater. The tank allows solids to settle at the bottom, forming sludge, while lighter materials, such as grease and oils, float to the top, creating scum. The liquid effluent that remains in the middle is then directed to a soakaway, which is a drainage system that disperses the treated wastewater into the surrounding soil. This process not only helps in the decomposition of organic matter but also minimizes the risk of groundwater contamination.
Building a septic tank and soakaway requires careful planning and execution. It involves understanding local regulations, selecting appropriate materials, and ensuring proper installation to prevent future issues. Improperly constructed systems can lead to costly repairs, environmental hazards, and health risks. Therefore, it’s crucial to approach this task with the right knowledge and tools.
In this comprehensive guide, we will walk you through the essential steps of building a septic tank and soakaway. From planning and design to installation and maintenance, we aim to provide you with the information needed to successfully complete this project.

Building Your Own Septic Tank and Soakaway: A Step-by-Step Guide
Constructing a septic tank and soakaway system is a significant undertaking that requires careful planning and execution. This guide will provide you with detailed steps to ensure that your system is built correctly and functions efficiently.
Understanding Local Regulations
Before you begin, it’s crucial to familiarize yourself with local regulations regarding septic systems. Different regions have specific codes and requirements that must be adhered to. Failing to comply can result in fines or the need to redo your work. Here are some steps to consider:
– Contact Local Authorities: Reach out to your local health department or environmental agency to understand the regulations.
– Obtain Necessary Permits: Ensure that you have all required permits before starting construction.
– Consult with Professionals: If unsure, consider consulting with a septic system professional to guide you through the legalities.
Planning and Design
Once you have a clear understanding of the regulations, the next step is to plan and design your septic system. This involves several key considerations:
– Site Selection: Choose a location that is away from water sources, such as wells or streams, and has good drainage.
– Soil Testing: Conduct a percolation test to determine the soil’s absorption capacity. This will help you decide the size and type of soakaway needed.
– System Size: Calculate the size of the septic tank based on the number of bedrooms in your home. A general rule of thumb is:
– 1-2 bedrooms: 750 gallons
– 3-4 bedrooms: 1000 gallons
– 5+ bedrooms: 1250 gallons or more
Materials and Tools
Gather the necessary materials and tools before you start construction. Here’s a list to get you going:
Materials:
– Concrete or fiberglass for the septic tank
– PVC pipes for drainage
– Gravel for the soakaway
– Geotextile fabric to prevent soil clogging
Tools:
– Shovel and spade
– Level
– Tape measure
– Wheelbarrow
– Safety gear (gloves, goggles, mask)
Construction Steps
Now that you have your plan and materials ready, follow these steps to build your septic tank and soakaway:
1. Excavate the Site:
– Use a backhoe or shovel to dig a hole for the septic tank and soakaway. Ensure the hole is deep enough to accommodate the tank and the drainage field.
2. Build the Septic Tank:
– If using concrete, pour the concrete into forms to create the tank. Ensure it is watertight.
– If using a pre-made fiberglass tank, lower it into the hole carefully.
3. Install Inlet and Outlet Pipes:
– Connect the inlet pipe from your home to the septic tank. This pipe should slope downward to allow gravity flow.
– Install the outlet pipe that will lead to the soakaway.
4. Create the Soakaway:
– Dig trenches for the soakaway, typically 3-6 feet deep and 2-3 feet wide.
– Place a layer of gravel at the bottom of the trench, followed by a layer of geotextile fabric to prevent soil from clogging the gravel.
5. Backfill and Compact:
– Backfill the area around the septic tank and soakaway with soil, compacting it as you go to prevent settling.
6. Test the System:
– Once everything is in place, run water through the system to ensure there are no leaks and that the effluent flows properly.
Maintenance Tips
To ensure the longevity and efficiency of your septic system, regular maintenance is essential. Here are some tips:
– Regular Pumping: Schedule pumping every 3-5 years, depending on usage.
– Monitor Water Usage: Be mindful of water usage to prevent overloading the system.
– Avoid Chemicals: Do not flush harmful chemicals down the drain, as they can disrupt the natural bacteria in the tank.
– Inspect Regularly: Check for signs of failure, such as slow drains or foul odors, and address issues promptly.
Conclusion
Actionable Recommendations for Building a Septic Tank and Soakaway
Building a septic tank and soakaway system is not just about following steps; it requires careful consideration and adherence to best practices. Here are actionable recommendations to ensure your project is successful and sustainable.
