Storage tanks should be located at least how far from the sewage disposal system?

• A. 5 feet
• B. 300 feet
• C. At least 50 feet from the sewage disposal system.
• D. 100 feet from the sewage disposal system.

Answer: (C)

Maintaining a safe setback between storage tanks and a sewage disposal system is about preventing cross-contamination and vapor migration while allowing access for maintenance. A minimum distance of 50 feet provides a practical buffer that reduces the chance of leaks, backflow, or odorous gases reaching the disposal area or contaminating nearby groundwater. It also gives space for monitoring and emergency containment without interfering with the disposal system’s operation. Closing in to 5 feet would be unsafe and increase contamination risk, while distances like 100 or 300 feet exceed the typical minimum and aren’t necessary for this specific scenario unless dictated by local codes. So, at least 50 feet is the correct, efficient standard.
