The system outlet, whether an open channel or a closed pipe, must be large enough to carry the desired drainage discharge from a field quickly enough to prevent significant crop damage.
January 2003 Subsurface drainage usually uses buried perforated or slotted hollow pipe called drain tile. Excess water in the soil enters and is carried away by gravity. In urban areas, these pipelines drain excess water from foundations and lawns. Tiles are made of concrete, clay, perforated plastic, or other materials designed for subsurface 14-10-2019В В· A subsurface drainage system that removes excess water from a field within a day or two of a big storm can help to provide plants with an adequate amount of both water and oxygen. Ad An agricultural drainage system is usually composed of pipes or open channels that carry extra water out of the field to a drainage ditch or a natural waterway, such as a stream.

Perforated plastic drain tubes are placed between 1 and 2 m below the soil surface. The technique was originally called tile drainage because tile cylinders were laid end to end in a trench.

Sometimes, a subsurface drainage system is installed in soils with a low infiltration capacity, where a surface drainage problem may improve the soil structure and the infiltration capacity so greatly that a surface drainage system is no longer required.
