Septic systems are essential for wastewater treatment in areas without access to municipal sewage systems. They ensure that human waste and other wastewater are safely processed and returned to the environment. However, people don’t create all septic systems equally. There are several different types of septic systems, each with its own design and functionality. In this article, we’ll explore the various types of septic systems to help you better understand which one may be right for your property.

Conventional Septic Systems
Conventional septic systems, also known as gravity septic systems, are the most common type. They consist of three main components: a septic tank, a distribution box, and a drainfield. Here’s how they work:
- Wastewater from your home flows into the septic tank, where solids settle and bacteria break down the organic matter.
- The liquid effluent then moves to the distribution box, which evenly distributes it to the drainfield.
- In the drainfield, the soil further treats the effluent as it percolates, undergoing natural filtration and purification.
Conventional septic systems are simple and effective but require proper maintenance to prevent clogs and failures.
Aerobic Treatment Units (ATUs)
Aerobic Treatment Units, advanced septic systems, use oxygen to break down wastewater more efficiently. These systems are ideal for properties with poor soil conditions or limited space. ATUs have three stages:
- Primary treatment in a septic tank, similar to conventional systems.
- An aerobic chamber where oxygen is introduced to promote the growth of beneficial bacteria for enhanced wastewater treatment.
- A final settling tank where treated effluent separates from remaining solids before being released into the soil or discharged.
ATUs are known for producing higher-quality effluent and may require more maintenance than conventional systems.
Mound Systems
Mound systems are designed for properties with shallow or unsuitable soil, high groundwater levels, or other limiting factors. Instead of relying on natural soil absorption, a mound system elevates the drainfield above ground level. Here’s how they work
- Wastewater from your home enters a septic tank for primary treatment.
- The treated effluent is pumped to a specially constructed mound made of sand, gravel, and soil.
- The mound provides additional filtration and treatment before the effluent gradually disperses into the native soil beneath.
Mound systems can be more expensive to install and maintain due to their unique design.
Pressure Distribution Systems
Pressure distribution systems are similar to conventional septic systems but use a pump to evenly distribute effluent to the drainfield. These systems are suitable for properties with uneven or challenging terrain. The pump ensures uniform effluent distribution, promoting efficient treatment and preventing clogs.
Alternative Septic Systems
In areas with stringent environmental regulations or specific needs, alternative septic systems may be required. These systems can include technologies such as sand filters, constructed wetlands, and advanced treatment units to achieve higher levels of wastewater treatment.
Selecting the right septic system for your property depends on factors like soil conditions, space, local regulations, and budget. Understanding the different types of septic systems is essential to make an informed decision. Regular maintenance and proper care are key to ensuring the longevity and effectiveness of any septic system, safeguarding both your property and the environment.
