What is the minimum required inches of bedding for piping trench?

In underground storage tank systems, proper installation of piping is crucial to ensure safety and functionality. The minimum required bedding for a piping trench is typically specified to provide support and protection for the piping against the surrounding soil and potential environmental factors. A bedding of 6 inches helps achieve this by allowing sufficient material to cushion the pipes, minimizing the risk of damage from settling or shifting soil over time. This bedding layer also aids in drainage, reducing the likelihood of water accumulation that could lead to corrosion or other deterioration of the piping.

Specifications like these come from regulatory requirements and industry best practices, which emphasize the need for adequate support and protection in underground installations. Using the correct bedding depth ensures that the pipes can operate efficiently and safely, maintaining the integrity of the overall system.
