The drain field is among the most vital parts that make the septic system work. The drain field 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 in your drain field. 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 drain field. Drain fields can also be mentioned as leach fields or leach drains. It's a soil subsurface area that is a disposal facility for wastewater. The drain field removes impurities and contaminants within the water. The dirt within the water is going to be treated by the bacteria within the drain field. The wastewater has already been treated by the bacterial anaerobic digestion inside the septic tank. The treatment in the drain field is the final step before the water gets combined with the other water tables

The drain field is usually made of trenches with pipes and porous materials like gravel 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 drain field 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 drain field is found is often mentioned as a septic reserve area.

Why is that the drain field vital?

The drain field 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 drain field 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 drain field?

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


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


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


The drain field must be large enough to handle the enormous volume of sewage it will get every day. If the drain field 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 drain field.


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