Understanding the Different Septic System Designs: Pros and Cons 1

What are Septic Systems?

Septic systems are essential for households and businesses that do not have access to the public sewer system. The septic system is an underground wastewater treatment system installed on your property. It is responsible for treating the wastewater produced by your home or business and returning it to the environment. A septic system comprises four main components: the septic tank, distribution box, drain field, and soil.

Understanding the Different Septic System Designs: Pros and Cons 2

Types of Septic Systems

There are different types of septic systems, and each has its unique pros and cons. The most common types are:

  • Conventional septic tank system
  • Chamber system
  • Aerobic treatment unit (ATU)
  • Septic mound system
  • Drip distribution system
  • Conventional Septic System

    The conventional septic tank system is made up of two main parts: the septic tank and the drain field. Wastewater flows from the property’s plumbing into the septic tank, where it is treated and separated through the use of natural bacteria. The solids settle to the bottom of the tank as sludge, while the scum floats to the top of the tank. The wastewater that remains is then released into the drain field, where it further gets treated naturally as it filters through the soil.


  • Easy installation and maintenance
  • Low maintenance cost
  • Cons: Want to know more about the topic? https://www.clearriverenvironmental.com/cesspool-service-near-huntington-ny, we suggest this to improve your reading experience and expand your understanding.

  • Requires adequate space for a drain field
  • Cannot be installed in areas with high groundwater table
  • If not maintained properly, the system can malfunction
  • Chamber System

    A Chamber system consists of a series of connected chambers placed in the soil. Chambers are designed to be lightweight, making the installation process easy. The wastewater flows into the chambers, where it gets treated using natural processes.


  • Lower installation footprint
  • Less cost than other options like mound systems
  • Cons:

  • It needs a large area for installation
  • Maintenance can be challenging and expensive
  • Aerobic Treatment Unit (ATU)

    An Aerobic Treatment Unit (ATU) or a biological unit is a wastewater treatment system that uses aerobic bacteria to treat the wastewater. ATU uses forced air to provide oxygen to naturally occurring bacteria, providing optimal conditions for them to mimic and purify the wastewater.


  • Much smaller footprint required for installation
  • Reduced environmental impact compared to conventional systems
  • Cons:

  • Expensive to install and maintain
  • The system requires electricity to operate
  • Septic Mound System

    A septic mound system is specifically designed for areas with high groundwater table or clay soil. It comprises gravel-filled an elevated soil mound to get better drainage. It has pipes that distribute wastewater through the gravel, which further filters the wastewater.


  • It is particularly useful in areas with poor soil
  • Great for small lots
  • Cons:

  • Needs periodic maintenance, or it can malfunction
  • Drip Distribution System

    A drip distribution system is a good alternative for challenging installations sites. The system comprises a series of small, flexible plastic tubes installed above the soil surface via a pressurized pump. The drip system applies small bits of wastewater evenly over the soil’s surface, allowing them the opportunity to get absorbed slowly and infiltrated by the soil.


  • Very low public health risk
  • Very effective at treating wastewater
  • Cons:

  • Needs periodic maintenance, or they can malfunction
  • Conclusion

    A septic system could be an economical and effective solution for homes or businesses in areas without access to the public sewer system. It is essential to consider the advantages and downsides of different septic system designs to make an informed decision before installing one. Work with a professional designer or an engineer to help you choose the septic system that best suits your requirements.
