What is required if a minimum of 12 inches of cover cannot be maintained for underground piping?

When underground piping cannot maintain a minimum cover of 12 inches, the regulations allow for a reduction of the cover to 12 inches if the installation is not located in traffic areas. This provision is important as it acknowledges different risk levels based on location. Traffic areas impose additional stress and potential damage from vehicle loads, which creates a greater need for protection. Therefore, if the piping is situated away from these stresses, a slight reduction in cover can be permitted while still adhering to safety standards.

The allowance for this reduction in highly trafficked areas is rooted in the understanding of how the environment affects the integrity and safety of underground installations. This consideration promotes responsible engineering practices while ensuring that the piping remains adequately protected under less strenuous conditions. Thus, the option regarding reducing the cover to 12 inches, contingent upon the absence of traffic risk, aligns with industry safety practices and regulations.
