What is the purpose of surface drainage?

The fundamental purpose of surface drainage system design and construction is to remove water from the surface as quickly as possible while minimizing soil erosion that can occur when water travels too quickly. Surface drainage systems also provide for the appropriate distribution of water during periods of excessive rainfall.

Surface drainage helps control flooding by removing excess water from the surface of the land as quickly as possible. The faster water can be removed, the less likely it will cause flooding. Also, surface drains help prevent puddles from forming on your lawn which could lead to mosquito breeding if they remain untreated. Puddles tend to attract animals who will eat the plants in your yard if you don't clean them up!

Surface drains should be installed near the bottom of a property line or at least 12 inches away from any tree trunk or large rock formation. The drain should be placed so that the inlet is over an area where water may collect (such as after a rain or when it's snowing) and the outlet is toward a dry area or into a trench. Make sure that the hole dug to install the drain is deep enough to accommodate an average rainfall event. Drains should not be placed under roadways or other areas where damage might be caused by water flowing through them.

The location of surface drains affects how they perform their function.

What is drainage?

The natural or artificial removal of surface and subsurface water from a region with an excess of water is referred to as drainage. Drainage is important for preventing flooding and other problems caused by excessive moisture.

Drainage can be accomplished through the use of ditches, pipes, reservoirs, and other devices. It is also possible to improve the ability of soil to drain naturally. The earth beneath and around buildings becomes saturated with water during periods of rain or melting snow. This water must be removed before it causes damage to the foundation or interior of the building.

Drainage systems take away water that would otherwise remain near its original place of deposition (as liquid water or groundwater), causing environmental problems such as soil erosion and flooding. The word "drain" comes from the French word "dérainer," which means "to discharge." Thus, drainage involves removing water so that it cannot replenish itself.

There are two types of drainage systems: active and passive. Active systems use power to remove water, while passive systems allow water to flow through them into nearby waterways or out of sight into underground chambers. Modern buildings often include some form of active system for collecting and carrying away storm water.

What is surface and subsurface drainage?

When the drainage problem is mostly caused by shallow water tables, subsurface drainage methods are utilised. A combined surface and subsurface drainage system is necessary when both surface and subterranean waterlogging occur. Wells are usually preferred over pipe drainage or ditches. They are more efficient than pipes and do not cause as much damage to land.

Surface drainage systems involve laying of conduits on the ground or underpasses to conduct water away from buildings or foundations. This type of system is used where there is sufficient space around structures for trenches or drains to be dug. The water will flow through the conduit into an adjacent gully or storm drain.

Subsurface drainage systems consist of excavating holes and channels beneath buildings or pavement surfaces with or without backfilling them with gravel or sand. The holes should be large enough to allow water to seep through. They may be open pits or closed cells in a polymeric material. These underground channels will lead water away from buildings or foundations.

Drainage problems can arise because water does not have a place to go. In such cases, surface drains or gutters should be installed to carry away excess water. If this fails, then sub-surface drainage systems may be required.

The location and size of these drainage systems affect how often they need to be maintained or replaced.

What are the advantages of a drainage system?

Some of the benefits of a drainage system are as follows:

  • Prevents Water Accumulation. Too much accumulated water on your lawn can lead to flooding which can in turn kill your plants.
  • Reduces Soil Erosion. Stagnant water can make soil muddy which will cause it to erode.
  • Removes Toxic Materials.

What is the function of drainage?

One of the drainage system's duties is to collect surface and/or ground water and send it away from the ballast bed, so keeping it drained. The drainage system must also safeguard the substructure against erosion, soddening, and loss of load-bearing capacity and stability. Finally, the system should not cause a rise in ground water levels around buildings or at parking lot edges.

The function of drainage is twofold: first, to remove water from areas where it is not wanted; second, to allow it to drain away from structures and their surroundings. If not removed, water can accumulate which may lead to problems such as flooding, structural damage, or soil saturation. Allowance for water removal and drainage are therefore essential in any structure design. In general, the closer together the openings through which water escapes, the faster this will happen. However, there should be space between each opening to prevent small objects from getting caught in them. This would be dangerous for people walking by or using the area regularly!

Drainage systems can be divided into three main types: natural, artificial, and combined. Natural drainage systems rely on gravity to carry water away from building sites. This type of system should be used wherever possible because it does not require maintenance. Artificial drainage uses pumps or other devices to remove water from close to the source. These systems can be effective in reducing flooding near buildings but can also lead to increased costs of construction.
