Above Ground vs. Underground Septic Systems

Knowing the main variations between above-ground and underground systems will help you decide which septic system best fits your property. Both have their benefits and limitations, but the right option depends on your specific needs, soil conditions, and budget.

In this blog post, our professionals from Septic Blue of Raleigh will explore the pros and cons of each type and help you make an informed decision.

What Are Above-Ground Septic Systems?

Often called mound systems, above-ground septic systems are intended for places where conventional underground systems would not be appropriate. An above-ground system can be the preferable choice if your property features poor soil drainage, shallow bedrock, or a high water table. These systems use layers of sand or gravel to create a filtration system on the surface, allowing wastewater to be treated and filtered more effectively.

The main advantage of an above-ground system is that it can be installed in areas with challenging soil conditions. The disadvantage is that these systems can be more visible and occupy more space, therefore influencing the look of your landscape.

What Are Underground Septic Systems?

Residential homes most often choose underground septic systems, sometimes referred to as conventional systems. These underground systems cleanse wastewater by depending on the natural filtration of the ground. If your soil is well-draining and your property has plenty of space, an underground system might be the most efficient and discreet option.

One of the key benefits of an underground system is that it is hidden from view, keeping your yard’s aesthetics intact. However, it's crucial to schedule regular septic tank pumping and cleaning to ensure the system continues to work efficiently. Ignoring these chores can result in expensive repairs or even a total system breakdown.

Installation Costs and Considerations

The cost of septic tank installation varies depending on whether you choose an above-ground or underground system. Since they require extra supplies such as gravel, sand, and specialized tools, above-ground systems usually cost more. However, they are often necessary for properties with poor soil conditions, making them worth the investment in the long run.

Underground systems, on the other hand, are generally more affordable upfront. Less materials are needed and the system is buried below the surface, hence the installation process is easier. To assess the soil quality, slope, and water table of your property, you need to speak with a qualified septic company before deciding. They can offer qualified advice catered to your needs.

Maintenance Requirements

Long-term effectiveness of any kind of septic system depends on frequent maintenance regardless of their design. Based on your tank's size and family count, septic pumping should be done every three to five years. Failing to schedule regular pumping can lead to overflowing tanks, backflow issues, and costly septic tank repairs.

Another vital chore for both above-ground and below ground systems is septic tank cleaning. This process removes solid waste buildup that could clog pipes or filters and cause system failure. A professional company can perform this cleaning and ensure that your system is running smoothly.
