What is the minimum cover depth required over all underground metallic piping?

The minimum cover depth required over all underground metallic piping is important for several reasons, primarily to protect the piping from physical damage and environmental factors. A depth of 12 inches ensures that the piping is well-protected from surface activity, such as vehicle traffic, landscaping, or other excavation activities that might occur on the ground above.

Additionally, the 12-inch cover helps to mitigate the risk of corrosion and other environmental effects on metallic piping. This standard helps maintain the integrity of the system over time, reducing the likelihood of leaks and ensuring safe operation. Proper adherence to this depth also aligns with safety regulations and guidelines set forth by industry standards, aiming to prevent accidents and safeguard the public and property.
