By installing tile drainage, the water table is effectively lowered and plants can properly develop their roots. The lack of water saturation of soil permits oxygen to remain in the pores of the soil for use by roots. Drain tile prevents the roots from being under the water table during wet periods, which can stress the plants.
A diagram of a traditional French drain. A French drain [1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain [1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area.
Figure 1 classifies the various types of drainage systems. It shows the field (or internal) and the main (or external) systems. [2] The function of the field drainage system is to control the water table, whereas the function of the main drainage system is to collect, transport, and dispose of the water through an outfall or outlet. In some ...
The two stage drainage ditch is classified as a 'surface' sustainable drainage system, contrary to a sub-surface system. The two stage drainage ditch is a modification of the land whereby grass benches which serve as floodplains are formed within the land of the watershed of the water system, shown in the diagram to the right.

In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...
A French drain, PVC pipe, or other drainage system is installed in the newly made channel. The installed drain is covered with new cement. The installed drain is covered with new cement. The drainage system collects any water entering the basement and drains it to an internally placed sump pump system, which will then pump the water out of the ...
The high point of the vent system (the top of its "soil stack") must be open to the exterior at atmospheric pressure. On large systems, separate parallel vent stacks may also be run to ensure sufficient airflow, because the number of devices linked to an atmospheric vent, and their distances from it, are regulated by plumbing code.
