What is the minimum distance a septic tank must be located from a water supply line?

1. 5 feet

2. 10 feet

3. 15 feet

4. 20 feet

The correct answer is: 10 feet

The minimum distance a septic tank must be located from a water supply line is typically set at 10 feet. This requirement is in place to ensure that there is adequate separation between potential contaminants from the septic system and the potable water supply, which is vital for maintaining public health and safety. When septic tanks are located too close to water supply lines, there is an increased risk of contamination from pathogens and harmful substances that can affect the quality of drinking water. Separation distances are governed by health regulations and building codes, which aim to prevent any drainage or leakage from the septic system from reaching the water lines. This distance is designed to allow for natural filtration processes, which help mitigate risks associated with pathogens and chemicals that may be present in septic discharge. Therefore, maintaining a minimum distance of 10 feet is crucial for ensuring the integrity of the drinking water supply and protecting the health of those who use it.
