How do Drain Fields Work?

A drain field is a very important component of a septic system. It is an addition to the septic tank that helps in the proper disposal of wastewater from the tank. This drain field is best located in an open area, which will get a lot of sunshine. The presence of a properly installed drain field is very important in the proper functioning of the septic system and it will also help in stretching the life of the septic tank. The drain field is a vast area that will spread the water from the septic tank to the soil surrounding the pipe.

Even though all the people are aware of the presence of a drain field, a good percentage of the people are unaware about how do drain fields work? In order to understand the proper function of a drain field, it is important to know about the function of the entire septic system. Therefore, the initial step is to know about the structure of a septic system. The whole system consists of pipelines, a septic tank and the drain field. The sources of the wastewater in the building, such as the showers, toilets and the sinks will be connected to the septic tank through pipelines. These pipelines serve as the connectors between the septic tank and the sources. The wastewater from the sources is directed to the septic tank through pipelines.

The septic tank will be having an inlet and an outlet. The waste from the sources comes in to the septic tank through the inlet and the outlet will be connected to the drain field. The outlet to the drain field will be having a filtering device, which will prevent the solid waste particles from passing on to the drain field. There can be as much drain pipes as the availability of the area for the drain field. All the pipelines in the drain field will be connected to the outlet of the septic tank to provide equal amount of water to all the pipelines. The pipelines will be spread over the area of the drain field.

There is a specific mode to keep the fix the pipelines in the field. The pipes will be having small holes in it. The pipes will be kept on a layer of washed gravel. This is done to enable free flow of water from the pipes to the surrounding soil. The soil in the surrounding will absorb the water from the pipes and the chemical reaction that happens with the presence of oxygen helps in easy and natural disposal of the waste components as well as the water. Planting over the drain field can improve the efficiency of drain field.
