What is the minimum burial depth for pipe under driveways or roadways?

The minimum burial depth for pipes under driveways or roadways is specified to be 3 feet. This depth is essential to ensure that the pipes are adequately protected from the weight and stress imposed by vehicles passing overhead. Adequate burial depth reduces the likelihood of damage to the pipes from surface loads and prevents any potential disruptions to service.

Selecting a depth of 3 feet aligns with industry standards and best practices for the installation of private fire service mains, ensuring operational integrity and safety. While other options suggest deeper burial depths, they may not be necessary in most cases, as the minimum requirement is sufficient to provide the needed protection under typical conditions.
