What is the minimum cover required for underground (UG) piping systems?

The minimum cover required for underground (UG) piping systems is 12 inches. This standard is crucial for ensuring the safety and integrity of the piping system. Adequate cover helps protect the pipes from physical damage due to surface loads, such as vehicles or heavy equipment. It also serves to minimize the risk of accidental damage from digging or construction activities that may occur above the piping.

In addition to physical protection, adequate cover can also help prevent the ingress of soil and moisture, which can lead to corrosion and other types of degradation over time. Furthermore, adhering to these depth requirements is important for compliance with local regulations and standards, which are designed to enhance safety and reliability in the use of LP gas systems.

Understanding these requirements is vital for anyone involved in the installation or maintenance of underground piping systems, as it directly impacts safety and system longevity. While other depths may be specified for different materials or conditions, the standard of 12 inches is a widely recognized baseline for general underground piping applications.
