What is the recommended depth for burying lateral lines?

The recommended depth for burying lateral lines in irrigation systems is typically 6-12 inches. This depth is crucial for protecting the lines from damage caused by surface activities, including foot traffic, equipment movement, and seasonal frost. By burying the lateral lines within this range, you ensure that they are adequately insulated from temperature fluctuations that could cause freezing and that they are below the reach of general surface disturbances, which could lead to accidental ruptures or leaks.

Additionally, this depth helps in preventing any interference from surface irrigation practices or maintenance activities that could expose the lines. Furthermore, when buried in this range, lateral lines are less likely to be affected by soil erosion or other environmental factors, thus enhancing the longevity and effectiveness of the irrigation system. This depth is a balance between accessibility for maintenance and protection from physical and environmental damage.
