Septic system expansion made easy: a comprehensive guide for homeowners
What To Know
- Expanding a septic system becomes necessary when the existing system can no longer handle the wastewater generated by a household.
- By following the steps outlined in this guide, you can ensure that your septic system meets the growing wastewater needs of your household while protecting the environment.
- While it’s possible to do some parts of the expansion yourself, such as excavation, it’s highly recommended to hire a qualified contractor for the design, installation, and inspection of the system.
Expanding a septic system becomes necessary when the existing system can no longer handle the wastewater generated by a household. This can occur due to increased occupancy, renovations that add plumbing fixtures, or changes in usage patterns. Expanding a septic system involves increasing its capacity to treat and dispose of wastewater effectively. Here’s a comprehensive guide to help you understand the process:
Assess the Situation
Before expanding the septic system, it’s crucial to assess the current situation and determine the extent of the problem.
- Inspect the existing system: Check for signs of failure, such as slow drains, sewage backups, or pooling water around the drain field.
- Estimate wastewater flow: Calculate the average daily wastewater flow generated by the household using water usage data.
- Determine soil conditions: The soil type and permeability will impact the design of the expanded system.
Design the Expansion
The design of the expanded septic system should be based on the assessed data.
- Increase tank capacity: The septic tank needs to be enlarged to accommodate the increased wastewater flow.
- Add or extend drain field: The drain field is where the treated wastewater is dispersed into the soil. It may need to be extended or new lines added.
- Consider alternative technologies: In some cases, advanced treatment systems or alternative disposal methods may be necessary.
Obtain Permits and Approvals
Expanding a septic system typically requires permits and approvals from local authorities.
- Contact the local health department: They will provide guidance on regulations and permit requirements.
- Submit design plans: The design plans for the expanded system must be reviewed and approved by the health department.
- Obtain a building permit: A building permit may be required for the installation of the new system.
Installation
The installation of the expanded septic system should be performed by a qualified contractor.
- Excavation: The necessary excavation will be done to accommodate the larger tank and drain field.
- Tank installation: The new or enlarged septic tank will be installed and connected to the existing system.
- Drain field installation: The new or extended drain field lines will be laid and connected to the septic tank.
Inspection and Maintenance
After the installation is complete, the septic system should be inspected and regularly maintained to ensure proper functioning.
- Initial inspection: The system should be inspected by a professional to ensure it meets the design specifications.
- Regular maintenance: The septic tank should be pumped every 3-5 years, and the drain field should be inspected and cleaned as needed.
Other Considerations
- Cost: Expanding a septic system can be an expensive project. The cost will vary depending on the size and complexity of the expansion.
- Timeframe: The installation process can take several weeks or months, depending on the size of the project.
- Impact on property: The expansion may require additional land for the drain field, which could affect the property’s aesthetics.

Popular Questions
Q: Can I expand my septic system myself?
A: While it’s possible to do some parts of the expansion yourself, such as excavation, it’s highly recommended to hire a qualified contractor for the design, installation, and inspection of the system.
Q: How long will my septic system last after expansion?
A: The lifespan of an expanded septic system depends on its size, maintenance, and usage patterns. With proper maintenance, it can last for decades.
Q: Can I add a garbage disposal to my septic system after expansion?
A: Adding a garbage disposal can increase the solids load on the septic system. It’s best to consult with a professional to determine if your expanded system can handle the additional waste.
