Learn How To Put In A Septic Tank In Just 3 Easy Steps!

Installing a septic tank is an essential step for any homeowner who relies on an on-site wastewater management system. While it may seem like a daunting task, with proper planning and execution, you can successfully put a septic tank in your property. This comprehensive guide will provide you with detailed instructions and expert tips to ensure a seamless installation process.

Planning and Preparation

1. Determine the Size and Type of Septic Tank:

The size of your septic tank depends on the number of bedrooms in your home and the estimated wastewater flow. Consult with a professional to determine the appropriate size. There are various types of septic tanks available, including concrete, fiberglass, and polyethylene.

2. Choose a Suitable Location:

Select a location that is at least 10 feet away from your home’s foundation, 50 feet from any water sources, and on level ground. Ensure that there are no overhead obstructions, such as trees or power lines.

3. Obtain Permits and Inspections:

Most localities require permits for septic tank installation. Contact your local building department to obtain the necessary permits and schedule inspections throughout the process.

Excavation and Installation

4. Excavate the Hole:

Dig a hole for the septic tank that is approximately 1 foot wider and 1 foot deeper than the tank’s dimensions. The bottom of the hole should be level and free of rocks or debris.

5. Install the Septic Tank:

Lower the septic tank into the hole using a crane or other heavy equipment. Ensure that the tank is level and properly positioned.

6. Connect the Inlet and Outlet Pipes:

Connect the inlet pipe from your home’s plumbing system to the septic tank‘s inlet. Similarly, connect the outlet pipe to the distribution box or drain field.

7. Backfill the Hole:

Backfill the hole around the septic tank with compacted soil. Use a tamper to ensure that the soil is firmly packed.

Drain Field Installation

8. Dig the Trenches:

Excavate trenches for the drain field that are at least 4 feet wide and 2 feet deep. The length and number of trenches depend on the size of your septic tank.

9. Install the Perforated Pipes:

Place perforated pipes in the bottom of the trenches. These pipes will allow wastewater to seep into the surrounding soil.

10. Cover the Pipes with Gravel:

Spread a layer of gravel over the pipes to prevent soil from clogging the perforations.

11. Backfill the Trenches:

Backfill the trenches with compacted soil. Ensure that the soil is level and slopes away from the septic tank.

Final Steps

12. Install the Distribution Box:

Connect the outlet pipe from the septic tank to the distribution box. The distribution box distributes wastewater evenly to the drain field.

13. Cover the Septic Tank and Drain Field:

Cover the septic tank and drain field with soil. Grass or other vegetation can be planted on top to blend them into the landscape.

14. Inspect and Maintain Regularly:

Schedule regular inspections of your septic tank and drain field to ensure proper functioning. Pumping the septic tank every 3-5 years is typically recommended.
