What is the minimum depth required for a service line that connects to the main?

The minimum depth required for a service line that connects to the main is typically 24 inches. This depth is crucial to protect the service line from freezing temperatures and potential damage from surface activities or changes in weather conditions. Installing the service line at this depth ensures that the water within the line remains at a stable temperature, reducing the risk of freezing, which can lead to costly repairs and interruptions in service.

In many jurisdictions, code requirements dictate this minimum depth to ensure safety and functionality in water delivery systems. It also prevents physical damage to the line from surface loads, such as vehicles or construction activities, which might otherwise compromise the integrity of the service line. The depth can vary in different regions based on local climate conditions, but 24 inches is a standard practice in many areas.
