What is the maximum depth of the trench subsurface drain tile if the soil has satisfactory absorption?

The maximum depth of a trench subsurface drain tile is influenced by the absorption capacity of the surrounding soil. When the soil has satisfactory absorption, it is able to effectively manage and drain excess moisture without becoming saturated, which might lead to ineffective functioning of the drain tile.

A depth of 2 feet 1 inch is appropriate because it ensures that the drain tile remains within an optimal range where efficient drainage occurs while also reducing the risk of potential soil saturation. This depth allows for adequate space to effectively collect and direct water away from the area.

Deeper configurations, such as 3 feet or more, may be unnecessary for soils that already demonstrate good absorption. Such depths could complicate installation, increase costs, and may lead to challenges with potential groundwater interference. Therefore, aiming for a maximum depth of 2 feet 1 inch is suitable for ensuring effective drainage in satisfactory absorbing soil conditions.
