Can We Plant Trees Around Outside of Mound Septic Systems?

When it comes to landscaping and beautifying our outdoor areas, planting trees is always a great idea. However, if you have a mound septic system on your property, you may be wondering if it is safe to plant trees around it. In this article, we will explore this question and provide you with some insights on planting trees around mound septic systems.

Understanding Mound Septic Systems

Mound septic systems are a type of onsite wastewater treatment system that is designed for areas that have poor soil quality or are located close to groundwater sources. The system consists of a septic tank for holding the wastewater and a raised bed or mound of soil that is built on top of the area where the soil is unsuitable for absorption.

As the wastewater from the septic tank flows through the pipes or chambers buried in the mound, it is treated and filtered by the soil, which acts as a natural filter. Eventually, the treated water is released to the surrounding groundwater sources.

Risks of Planting Trees Around Mound Septic Systems

While planting trees around mound septic systems may seem like a good idea, it can actually pose several risks to the system and your property. The roots of trees can grow deep into the soil and potentially damage the pipes or chambers of the system buried within the mound.

If the roots penetrate the chambers or pipes, they can cause blockages, leading to a malfunction of the system. This can result in backups of wastewater in your home, unpleasant odors, and even costly repairs.

Additionally, planting trees too close to the mound can create issues with the absorption capacity of the soil, which can cause the system to fail prematurely. The roots of trees can also cause instability of the mound structure, which can lead to collapse or erosion of soil from the mound.

Guidelines for Planting Trees Near Mound Septic Systems

While planting trees near mound septic systems is not recommended, if you must plant trees, there are some guidelines that you should follow to minimize the risks.

Firstly, it is essential to plant trees at a significant distance from the mound, ideally 50 feet or more to avoid any damage to the system. Secondly, you should choose trees with shallow root systems that will not penetrate deep into the soil; some varieties of trees that are suitable for planting near mound septic systems include Japanese maple, dogwood, and redbud.

Furthermore, you should avoid planting large trees that require a lot of water or nutrients, as they can put additional strain on the mound's soil absorption capacity. You should also avoid planting trees on top of the mound or on the sides where the lateral lines of the system are located.

Conclusion

Planting trees can undoubtedly enhance the beauty of your property, but when it comes to mound septic systems, caution is essential. While it is not advisable to plant trees around mound septic systems, if you must, use suitable guidelines and consult with a professional to ensure that you do not cause any damage to the system or your property.
