Your drain field is a significant part of any septic system. What a person may not realize is that these fields are not a one size fits all kind of thing. There are a few different types of fields, each one uniquely suited for a different purpose. Let’s examine these different drain fields and see what the differences are between them.

Different Type Of Drain Fields

There is not just one size fits all when it comes to these systems. Many factors go into what type of drain field your property should have. Let’s look at the different options for septic drain fields.

Conventional drain field design – for people who have the perfect soil and ideal yard conditions, this is the type of drain field you will need. When an individual thinks of a drain field, this is most likely the style they have in mind. In this kind of field, a rectangular trench is dug in your yard that is surrounded by gravel. Pipes are placed through the field. The liquid that enters the field travels through the pipes and then into the ground. This type is not visible because it is built underground.

Mound/Elevated Seepage Bed System – this type of drain field works best for properties that have extremely hard soil. This style is also used where there is a risk of the drain field being too close to the supply of groundwater. In this type of system, all the liquid comes to the mound and then flows out of the mound via a pipe. This system is visible as the mound is built above ground.

Dry well systems – this system is quite close to the conventional drain field design. The difference between this style and the conventional style is that in this model, the field is lined with crushed rocks or gravel. There are no pipes used in this type of drain field. This style is also built underground and is not visible.

Chamber style system – this style is a newer kind of design in the world of drain fields. In this model, all of your liquids enter a plastic chamber. The liquid then enters the ground via the plastic chamber, eliminating the need for the classic gravel or stone filled bed. This system has a shorter life span but is much less expensive than the other styles. It is also built underground.

Benefits Of The Different Styles Of Drain Fields

No matter which style you pick, each type of field is effective in helping manage your wastewater in an environmentally sound way. All will treat your effluent and move it out of your yard.

If you are concerned about your field being visible, all but the mound style system are built below ground. The conventional, dry well, and chamber style all have the drain field or chamber hidden underground. However, even with the mound/elevated seepage bed system, there are ways to conceal the mound, so it isn’t readily seen. All of these drain field styles are also recognized as durable, although the chamber method will need replacing before any of the others. With that being said, it will still last between 15-20 years.

There is also a great deal of balance across the levels of maintenance each individual type of tank requires. Chamber style systems need more monitoring and maintenance but have fewer parts, which lowers repair costs. The reverse is true for the other systems, so you may need less monitoring, but there are more parts to the system. The costs for maintaining each system ends up being about the same.

How To Tell When Your Drain Field Is Experiencing Issues?

While some fields need more monitoring than others, there are universal signs that your drain field is having an issue. The first being if there is standing water around the location of your field. Another is the smell of sewage in your yard or inside your home. Slow draining sinks and showers are another sign that there may be distress in your drain field. If you notice any of these, contact a professional right away. Your septic system could need pumping or require some other type of repair.
