How to Safely Check Septic Tank Field Lines for Post Holes
Installing or repairing posts on your property can be a straightforward task, but it's crucial to ensure that you do not accidentally damage your septic system. This guide will walk you through the necessary steps and precautions to safely check the location of your septic tank field lines before digging for post holes.
1. Contact Your Local Building Department and Plumbing Inspector
The first step is to contact your local building department or plumbing inspector's office. They can provide you with recorded plans of your septic system and ensure that your fence meets local codes.
It's essential to retrieve the original permit information as the plans for your septic system should be on file at the building department. This information might also be available online through the city or county website. Additionally, make sure to check if you need a permit before starting any excavation work.
2. Check During Summer for Clear Indicators
Timing is key when checking for septic tank field lines. The best time to do this is during the summer months, when the grass and soil are more visible and moist. The grass over the field lines should be greener, and the soil should feel damp, especially during dry periods.
A hard test probe, particularly one with a diameter of 3/8ths of an inch, should be able to penetrate the soil with ease, often aided by tapping with a hammer to break through any crust or hardpan.
3. Consult Your County Environmental Department
If you still cannot locate the field lines, consider visiting your county environmental department. They often have detailed drawings of your septic system layout and can provide you with the exact locations of the field lines, drains, and other components.
Be prepared to provide your property address and possibly a copy of your land survey or property deed. Staff there can guide you through the process and ensure that you are not excavating in a potentially hazardous area.
4. Implement Safety Protocols During Digging
Even with the best intentions and planning, digging for post holes can still pose risks to your septic system. Here are some safety protocols to follow to prevent damage:
Familiarize yourself with the exact location of the field lines and mark them clearly on the ground with stakes or paint.
Use manual tools like shovels or scrapers to dig horizontally around the marked field lines, slowly and gently probing the soil.
Be cautious of potential changes in soil type or moisture levels that may indicate close proximity to the field lines.
Stop digging if there's any doubt or if your probing causes the ground to shift or collapse.
Never use heavy machinery like backhoes or bulldozers in areas where the field lines are suspected.
Conclusion
Checking for septic tank field lines before digging for post holes is a critical step in protecting your property and ensuring the proper functioning of your septic system. By following these steps and implementing the necessary safety protocols, you can minimize the risk of damaging your septic system and ensure a safer and more successful installation of your posts.
