Georgia Septic Installer Practice Test

What is the required minimum placement distance for absorption line laterals?

1. 5 ft on center

2. 6 ft on center

3. 7 ft on center

4. 8 ft on center

The correct answer is: 7 ft on center

The correct answer indicates that the required minimum placement distance for absorption line laterals is 7 feet on center. This specification is important for ensuring that the septic system functions effectively and minimizes the potential for contamination and malfunction. Maintaining this minimum distance helps to provide adequate space for the absorption lines to operate properly. It allows for sufficient soil aeration and drainage, which is crucial for the natural treatment of waste as it passes through the soil. Proper spacing helps to prevent overlapping absorption areas, which could lead to overloading any single section of the system and ultimately result in system failure or environmental contamination. By adhering to the minimum spacing guidelines, installers can ensure that the effluent is adequately treated before it reaches the groundwater or nearby surface water bodies, thus safeguarding public health and preserving water quality.
