The purpose of a septic system is to break down and filter the waste, preventing it from contaminating groundwater, surface water, and the surrounding environment.
Knowing the various types of septic systems available and their respective advantages and disadvantages can help property owners make an informed decision that best suits their specific site conditions, local regulations, and long-term maintenance requirements. This article will explore the different types of septic systems, their features, and the factors to consider when choosing the right system for your property.
Conventional Septic Systems
Conventional septic systems are the most common and widely used type of septic system. These systems consist of a septic tank and a drainage field, where the treated wastewater is dispersed into the soil. The septic tank is responsible for the initial treatment of the wastewater, where solids settle to the bottom, and the liquid portion (effluent) is then discharged into the drainage field.
One of the primary advantages of conventional septic systems is their simplicity in design and operation. They do not require complex mechanical or electrical components, making them relatively low-maintenance and cost-effective to install and operate. Additionally, conventional systems are well-suited for properties with adequate soil depth and percolation rates, allowing for the effective absorption and filtration of the effluent.
However, conventional septic systems do have some limitations. They are typically less effective in areas with high groundwater tables, shallow soil depths, or poor soil drainage, as these conditions can lead to the system’s failure or reduced performance. In such cases, alternative septic system types may be more suitable. Proper installation and regular maintenance, such as periodic pumping of the septic tank, are also crucial for the long-term functionality of a conventional septic system.
Aerobic Septic Systems
Aerobic septic systems, also known as advanced treatment systems, are a more sophisticated type of septic system that utilizes an aerobic treatment process to break down and treat the wastewater. Unlike conventional systems, aerobic systems introduce oxygen into the treatment process, which helps to enhance the decomposition of organic matter and the removal of pathogens.
One of the primary benefits of aerobic septic systems is their ability to produce a higher-quality effluent that is more environmentally friendly. The aerobic treatment process results in a cleaner, less-polluted discharge, which can be more suitable for areas with sensitive environmental conditions or where the effluent is dispersed into a smaller drainage field.
Aerobic systems typically require more complex installation and maintenance compared to conventional systems. They often include mechanical components, such as an air compressor or blower, to introduce the necessary oxygen into the treatment process. Additionally, aerobic systems may have higher energy consumption and operational costs, as they require a continuous power supply to operate the mechanical components.
Despite the increased complexity, aerobic septic systems can be a viable option in situations where conventional systems are not suitable, such as in areas with high water tables, shallow soil depths, or poor soil percolation rates. Proper installation, regular maintenance, and monitoring are essential to ensure the long-term performance and efficiency of an aerobic septic system.

Mound septic systems, also known as elevated septic systems, are a specialized type of septic system designed for areas with challenging soil conditions or high groundwater tables. In a mound system, the septic tank and drainage field are constructed on top of a mound of sand or gravel, rather than being installed directly in the native soil.
The primary advantage of a mound septic system is its ability to function effectively in areas where the soil conditions are not suitable for a conventional or in-ground septic system. The mound provides an additional layer of filtration and treatment, allowing the system to be installed in areas with high water tables, shallow soil depths, or poor soil percolation rates.
The design and installation process for a mound septic system is more complex compared to a conventional system. The mound must be constructed with specific soil types and dimensions to ensure proper treatment and dispersal of the effluent. Additionally, the mound system may require more maintenance, as the pump and other mechanical components must be regularly serviced to maintain optimal performance.
Mound septic systems are often a suitable option for properties with limited space or challenging site conditions, where a traditional in-ground system is not feasible. However, the increased complexity and higher installation costs associated with mound systems should be carefully considered when selecting the appropriate septic system for a property.
Drip Irrigation Septic Systems
Drip irrigation septic systems, also known as subsurface drip dispersal systems, are a unique type of septic system that utilizes a network of small-diameter tubing to distribute the treated effluent directly into the soil. Unlike traditional drainage fields, drip irrigation systems disperse the effluent slowly and evenly throughout the soil, allowing for more efficient absorption and treatment.
One of the primary advantages of drip irrigation septic systems is their ability to function in areas with limited soil depth or poor soil percolation rates. The slow and even distribution of the effluent helps to prevent ponding or surfacing, which can be a common issue with conventional drainage fields. Additionally, drip irrigation systems can be designed to minimize the required land area for the dispersal field, making them a suitable option for properties with limited space.
Drip irrigation septic systems typically require more complex installation and maintenance compared to other septic system types. The network of tubing and associated components, such as pumps and filters, must be carefully designed and installed to ensure proper operation. Regular maintenance, including flushing the system and monitoring for any blockages or issues, is essential to maintain the long-term performance of a drip irrigation septic system.
While drip irrigation systems may have a higher initial cost, they can be a practical and environmentally-friendly option in areas with challenging soil conditions or where a smaller dispersal field is required. Consulting with a professional septic system installer or designer is recommended to determine if a drip irrigation system is the best choice for a particular property.
