The drainfield is among the most vital parts that make the septic system work. The drainfield installation is often supervised by a very reliable contractor. Once you opt to install a septic system installed in your home, the contractor will suggest the proper location to put it in your drainfield. You might think that you simply can place your septic system anywhere but the reality is that there are a variety of things that need to be considered.

The septic system is formed by a tank, pipes, and therefore the drainfield. drainfields can also be mentioned as leach fields or leach drain. It's a soil subsurface area that is a disposal facility for wastewater. The drainfield removes impurities and contaminants within the water. The dirt within the water is going to be treated by the bacteria within the drainfield. The wastewater has already been treated by the bacterial anaerobic digestion inside the septic tank. The treatment in the drainfield is the final step before the water gets combined with the other water tables

The drainfield is usually made of trenches that have pipes and porous materials like gravel that are covered with a layer of soil. The upper soil layer is placed to stop any animals or possible surface runoff from going to the wastewater that has been distributed to the trenches. The first design of a drainfield would have a hydraulic to handle the quantity of the wastewater that needs disposal and also because the catabolic is used for the long-term oxygen demand of the wastewater. The land location where the drainfield is found is often mentioned as a septic reserve area.

Why is the drainfield vital?

The drainfield is extremely essential because it helps in treating the wastewater. The pipes can help in moving the wastewater through the whole system into the soil. The soil obviates any harmful viruses, bacteria, and nutrients in the wastewater. After the water is filtered out, the drainfield discharges the liquid as groundwater which matches back to the system. If there's a filtration process, it's going to cause some serious health problems for the members of the household.

What are some of the factors which will influence the installation of the drainfield?

You might assume that you simply can have your drainfield installation anywhere in the yard. However, you've got to remember that some factors have an impression on the drainfield’s placement.


The type of soil where you would put your drainfield will have a serious impact on the functionality of the entire system. When you are deciding the area for your drainfield, you have to make sure that the soil has a good consistency. The soil must let the water flow but is quite fine to filter the effluent. A soil that is too coarse won't filter the effluent properly.


The terrain is one of the factors you have to think about when installing your drainfield. Avoid steep terrain. When there's rainfall or a heavy downpour, the drainfield may experience runoff issues that may damage and flood the drainfield. If your drainfield floods, it's going to cause damage to the whole system. Pick a flat surface to get the correct consistency to make the drainfield work properly.


If there's any landscape within the yard, it'll function as an element to work out where the drainfields are going to be installed. The drainfield installation should not be placed near any trees. This is because the roots of the plants may grow to the drainfield and damage it. It can also damage the pipes of the septic system. There should also be no obstructions in your drainfield and also avoid placing any heavy things on top of it.


It is vital that the drainfield would be large enough to handle the enormous volume of sewage it will get every single day. If the drainfield is small, it could easily overload and flood the system. When the flooding happens, it's going to cause some sewage to fill the pipes and could spill into the groundwater resulting in contamination. You have to properly choose the best area in your yard that might be large enough for your drainfield.

Drainfield Options

There are a few different drainfield options to choose from, each with its benefits and drawbacks. The three most common types of drainfields are:

  • Pipe Drainfield: This type of drainfield is made up of PVC pipes buried in the ground. The wastewater flows through the pipes and into the soil. This type of drainfield is typically less expensive to install, but it can be more difficult to repair or replace.
  • Sand Filter Drainfield: A Sand Filter drainfield uses sand to filter out the wastewater before it enters the soil. This type of drainfield is typically more expensive to install, but it is easier to maintain and repair than a Pipe Drainfield.
  • Soil Absorption Drainfield: A Soil Absorption drainfield uses the soil to filter out the wastewater. This type of drainfield is typically the most expensive to install, but it is also the most efficient and easy to maintain.

Each drainfield option has its benefits and drawbacks, so it's important to choose the option that best suits your needs.
