What is the setback distance from a lateral trench for streams?

• A. 25 feet
• B. 50 feet
• C. 70 feet
• D. 100 feet

Answer: (A)

The correct answer regarding the setback distance from a lateral trench for streams is 25 feet. This distance is determined based on the need to protect water quality in streams from potential contamination due to leachate from septic systems. A 25-foot setback helps ensure that any effluent from a septic system does not easily travel into the stream, which can lead to water pollution and impact aquatic ecosystems. This distance is typically a regulatory standard that aims to provide a sufficient buffer zone to mitigate risks associated with surface water contamination. In considering other setback distances, while they are often employed for different situations, the specific requirement for lateral trenches in proximity to streams is set at 25 feet to balance safety and practicality in septic system design and environmental protection.
