Georgia Septic Installer Practice Test

What is the minimum distance a septic tank must be from lakes and ponds?

1. 10 feet

2. 15 feet

3. 25 feet

4. 50 feet

The correct answer is: 25 feet

The minimum distance a septic tank must be from lakes and ponds is established to protect water quality and prevent contamination of natural water bodies. A distance of 25 feet is considered appropriate to ensure that when effluent leaks or slowly percolates from the septic tank, it does not adversely affect the nearby water resources. This buffer zone allows for the natural filtration of any contaminants as the sewage effluent travels through the soil before potentially reaching a water body. By maintaining this distance, state regulations aim to mitigate risks to public health and the environment, emphasizing the importance of adhering to minimum separation distances in septic system design and placement.
