The top of a pipe in a trench must be at least how many inches from the top of the ground?

The requirement for the top of a pipe in a trench to be at least 24 inches from the top of the ground is based on standards designed to ensure proper safety and function of the water infrastructure. This clearance helps prevent damage from surface activities, such as construction or landscaping, which might otherwise compromise the integrity of the pipe. It also allows for adequate soil cover to protect the pipe from external forces and environmental conditions, ensuring the water system remains operational without risk of contamination or failure. This standard is particularly relevant for utility installations, where maintaining proper depth can affect the long-term reliability and safety of the water delivery system.
