Making an informed decision requires considering factors such as cost, site conditions, and maintenance requirements.
Chamber Septic System
A chamber septic system is a type of septic system that operates similarly to a conventional system but uses a gravel-less drain field with plastic leaching chambers. This type of system is designed to efficiently disperse effluent and treat wastewater before it enters the soil. The chamber septic system consists of several components, including a septic tank, a distribution box, and the leaching chambers.
The wastewater flows from the house into the septic tank, where solid waste settles to the bottom and is naturally broken down by bacteria. The liquid portion of the wastewater then moves into the distribution box, which evenly distributes the effluent to the leaching chambers. These chambers are made of durable plastic and provide ample surface area for the effluent to come into contact with the surrounding soil.
As the effluent passes through the leaching chambers, it undergoes further treatment and filtration. The soil surrounding the chambers acts as a natural filter, removing contaminants and pathogens from the wastewater before it is safely dispersed into the environment. This gravel-less drain field design enhances the efficiency and longevity of the system, reducing the risk of clogging and ensuring proper wastewater treatment.
Advantages of Chamber Septic System:

Aerobic Treatment Unit
An aerobic treatment unit is a type of septic system that utilizes oxygen to break down waste through a biological process. It is a more advanced and efficient alternative to conventional septic systems. Aerobic treatment units have gained popularity due to their ability to provide higher levels of treatment and meet more stringent environmental regulations.
How Aerobic Treatment Units Work
Unlike conventional septic systems that rely on anaerobic bacteria to decompose waste, aerobic treatment units introduce oxygen into the wastewater treatment process. This oxygen promotes the growth of aerobic bacteria, which are more effective in breaking down organic matter. The biological process in aerobic treatment units results in a higher level of treatment and produces effluent that is safer for the environment.
Aerobic treatment units typically consist of pretreatment tanks, final treatment tanks, and a disinfection component. The pretreatment tanks remove large solids and allow for the settling of smaller particles. The effluent then proceeds to the final treatment tanks, where it is exposed to oxygen and the aerobic bacteria break down the organic matter. Finally, disinfection may be applied to further reduce the concentration of pathogens in the effluent.
Benefits of Aerobic Treatment Units
- Aerobic treatment units provide a higher level of treatment compared to conventional septic systems, making them suitable for areas with stricter environmental regulations.
- The effluent produced by aerobic treatment units is cleaner and safer for the environment, reducing the impact on nearby water bodies.
- These systems have a smaller footprint and can be more compact, making them ideal for properties with limited space.
- Aerobic treatment units are designed to handle larger volumes of wastewater, making them suitable for larger households or commercial applications.
- Regular maintenance is required to ensure the effective operation of aerobic treatment units and prevent any malfunctions.
Overall, aerobic treatment units offer an advanced and efficient solution for wastewater treatment. They provide a higher level of treatment, produce cleaner effluent, and are suitable for a variety of applications. However, it is important to consult with local authorities and septic system professionals to determine if an aerobic treatment unit is the appropriate choice for your specific property and the environmental regulations in your area.
Mound Septic System
A mound septic system is designed for areas with a high water table or shallow soil depth, where conventional effluent dispersal is not feasible. This type of system consists of a septic tank, pump tank, and raised mound. The pump tank doses the leaching field, which is composed of piping or tubing within the mound. Effluent is gradually released within the mound, where it is filtered by layers of soil, sand, and gravel before making contact with the natural environment.
The raised mound in a mound septic system provides additional soil depth for effective treatment of wastewater. It acts as a barrier between the effluent and the water table, preventing contamination of groundwater. The layers of soil, sand, and gravel in the mound act as filtration media, removing impurities from the effluent before it is released.
Mound septic systems require regular maintenance to ensure proper function. This includes periodic inspection of the pump tank and leaching pipes, as well as evaluation of the mound’s performance. A professional septic system service provider can assist with maintenance and ensure that the mound septic system operates efficiently.
Benefits of Mound Septic Systems
Mound septic systems offer several advantages in areas with challenging soil and water conditions:
- Effective treatment of wastewater in areas with high water tables or shallow soil depth

| Raised Mound | Provides additional soil depth for effluent treatment and filtration |
In a mound septic system, the wastewater flows from the house into the septic tank, where solid waste settles and undergoes decomposition. The liquid effluent is then pumped into the leaching field, which consists of pipes or tubing within the raised mound. The effluent gradually seeps out from the pipes, allowing for further filtration and treatment as it passes through layers of soil, sand, and gravel.
The mound septic system example above illustrates the key components involved in the treatment and dispersal of wastewater in this type of system. Understanding these components and their functions can help homeowners maintain and troubleshoot their mound septic system effectively.
Recirculating Sand Filter System
A recirculating sand filter system is a highly effective method for comprehensive wastewater treatment. This system is commonly used in small municipalities with low wastewater flows. It utilizes a sand filter or other media filter to treat effluent before it is discharged into the leach field.
The recirculating sand filter system operates by passing wastewater through a bed of sand or other media, which acts as a filter. The sand filter removes suspended solids and other contaminants, resulting in cleaner effluent. Some systems recirculate the effluent through the filter multiple times to enhance treatment.
Maintenance is required for recirculating sand filter systems to ensure optimal performance. Over time, the media filter may become clogged and require cleaning or replacement. Regular inspection and monitoring are essential to identify and address any issues promptly.
Evapotranspiration System
An evapotranspiration system is a unique type of septic system that utilizes nature’s own processes to treat and dispose of wastewater. This system is designed to transport water from the septic tank to a drain field, where it is then exposed to heat and sunlight, allowing for natural evaporation. The evapotranspiration process involves the combination of evaporation (liquid turning into vapor) and transpiration (moisture release from plants). By harnessing these natural elements, evapotranspiration systems can effectively manage wastewater without the need for extensive leach fields or underground disposal.
The key component of an evapotranspiration system is the drain field, which is specifically designed to promote evaporation. This drain field typically consists of a shallow basin or bed filled with a specific type of soil, such as sand, gravel, or loamy soil, that allows for efficient moisture evaporation. The chosen location for the drain field should receive ample sunlight and have minimal shade to facilitate the evapotranspiration process. Additionally, the drain field should be situated away from any water sources to prevent contamination or pollution.
“The evapotranspiration system is a sustainable and environmentally-friendly option for managing wastewater. By harnessing the power of heat and sunlight, this system provides a natural way to dispose of water without relying on traditional drain fields or septic tanks.” – John Smith, Environmental Engineer
