The Benefits of Mound Septic Systems: A Comprehensive Guide

 

 

 

 

 

If you're a homeowner or considering a septic system installation, you've probably encountered the term "mound septic system" in your research. It's an alternative septic system designed to treat wastewater and organic waste in areas where a conventional option is not possible due to unusual conditions.

That's why we created a short yet comprehensive guide on mound septic systems. Today we will explain how they work and the unique benefits they offer homeowners. So, let's dive in and discover why they are an excellent choice for many properties.

 

Understanding Mound Septic Systems
Mound septic systems are an alternative to conventional septic systems. They are typically used in areas with challenging soil conditions or locations that require additional wastewater treatment.

Unlike conventional options that rely on gravity and natural soil absorption, mound systems use an elevated mound of sand and gravel to treat and filter wastewater. This mound is built above the natural soil, creating an artificial drainfield.

The key components of a mound system include a septic tank, a dosing chamber, a pump and the mound itself. Wastewater enters the septic tank, where solids settle to the bottom, grease to the top, and effluent can pass through to the dosing chamber.

From there, a pump distributes the effluent evenly across the mound, where it percolates through the sand and gravel layers, undergoing filtration and treatment before reaching the underlying soil.

 

Mound System Benefits
Enhanced Treatment and Environmental Advantages
Mound septic systems provide advanced wastewater treatment as their elevated design promotes improved efficiency by increasing the contact time between the effluent and the layers of sand and gravel. As a result, the capacity for removing pollutants and reducing nitrogen levels is higher, thus providing increased protection for groundwater resources.

This heightened treatment capability makes mound septic systems particularly beneficial in environmentally sensitive areas. Properties near lakes, rivers, or coastal regions can benefit from the enhanced filtration and nutrient removal provided by such systems to safeguard nearby water bodies from contamination.

 

Increased System Longevity and Reliability
One of the more significant advantages of this type of system is its durability and reliability, especially in challenging soil conditions.

Raising the drainfield above the natural soil helps overcome clayey or poorly draining soil limitations. This minimizes the risk of drainfield failure, clogging, or hydraulic overloading, which can occur in conventional systems installed in unsuitable soil types.

Regular maintenance maximizes a mound septic system's longevity and efficiency.

Homeowners should adhere to some general rules:

●        - Stick to recommended pumping schedules

●        - Avoid excessive water usage

●        - Be mindful of what enters the system

●        - Diverting rainwater away from the mound

●        - Do not plant deep-rooted trees nearby

These preventative measures can help preserve the system's integrity.

 

Aesthetics and Landscaping Considerations
Creative landscaping designs can help integrate the elevated mound into the surrounding environment.

Planting suitable vegetation on the slopes or nearby the mound can soften its appearance and blend it with the rest of your backyard. Grasses, herbaceous (non-woody) or flowering plants that are tolerant of the mound's unique conditions can be chosen to enhance its aesthetic appeal.

Maintaining an attractive outdoor space while accommodating a mound septic system is possible with careful planning and regular maintenance. Regular mowing, pruning, and vegetation monitoring are necessary to keep the landscaping around the mound neat and well-maintained.

 

Cost Considerations and Return on Investment
The cost of installing a mound septic system may vary depending on site conditions, system size, and local labor and material costs. Generally, mound systems tend to be more expensive than conventional septic systems due to the additional materials and engineering involved.

However, it is important to consider the long-term savings and return on investment that mound systems can offer. The improved treatment efficiency may reduce the need for additional costly wastewater treatment solutions. Moreover, mound systems' increased reliability and durability can minimize the frequency of repairs or system replacements, resulting in long-term cost savings.

It is advisable to consult with a professional septic service company to obtain accurate cost estimates and discuss financing options or incentives that may be available for mound septic system installations.
