Concept of water drainage

The removal of excess water either from the ground surface or from the root zone is called drainage. Excess water may be caused by rainfall or by using too much irrigation water, but may also have other origins such as canal seepage or floods.

Drainage can be either natural or artificial. Many areas have some natural exterior drainage contractors near me; this means that excess water flows from the farmers' fields to swamps or to lakes and rivers.

There are two types of artificial drainage:

1. Surface drainage

Surface drainage is the removal of excess water from the surface of the land. This is normally accomplished by shallow ditches, also called open drains. The shallow ditches discharge into larger and deeper collector drains. This is site prep services. In order to facilitate the flow of excess water toward the drains, the field is given an artificial slope by means of land grading.

2. Subsurface drainage

Subsurface drainage is the removal of water from the root zone. It is accomplished by deep open drains or buried pipe drains.

Deep open drains - The water drainage contractors near me from the root zone flows into the open drains. The disadvantage of this type of subsurface drainage is that it makes the use of machinery difficult.

Pipe drains - Pipe drains are buried pipes with openings through which the soil water can enter. The pipes convey the water to a collector drain

Deep open drains versus pipe drains - Open drains use land that otherwise could be used for crops. They restrict the use of machines. They also require a large number of bridges and culverts for road crossings and access to the fields.
