Comparing Septic Systems: Which One is Right for You?

Septic systems are an essential part of residential and commercial infrastructure, and they play a critical role in disposing of waste and maintaining a healthy environment. When it comes to septic systems, there are various options to choose from, including city sewer, conventional systems, chamber systems, drip distribution systems, aerobic treatment units, mound systems, recirculating sand filter systems, evapotranspiration systems, constructed wetland systems, and cluster/community systems. In this article, we’ll explore each of these options to help you determine which septic system is best for your property.

City Sewer System

City sewer systems are centralized systems that collect and treat wastewater from multiple properties. This system is typically run by the local government, and the costs are usually paid through property taxes or utility bills. City sewer systems are a convenient option as property owners don’t need to worry about maintaining their own septic system. However, city sewer systems are only available in urban areas, and the cost can be significantly higher than other options.

Conventional System

The conventional septic system is the most common type of septic system used in residential properties. This system consists of a septic tank that collects wastewater from the property and allows solids to settle at the bottom while allowing the liquid to flow into the drain field. The drain field then filters the liquid through the soil and into the groundwater. Conventional systems are relatively simple, cost-effective, and low maintenance. However, they may not be suitable for all soil types and may not be able to handle heavy water usage.

Chamber System

Chamber systems are similar to conventional systems, but instead of using a drain field, they use a series of interconnected chambers that filter the liquid through the soil. The chambers are made of plastic and have a perforated design that allows the liquid to flow through. Chamber systems are more compact than conventional systems, making them a great option for properties with limited space. They are also cost-effective and easy to install.

Drip Distribution System

Drip distribution systems are designed to distribute the wastewater from the septic tank evenly across the drain field using a series of small drip emitters. This system is efficient as it delivers small amounts of water at a time, which is ideal for properties with limited soil absorption capabilities. Drip distribution systems are easy to maintain and can last for many years with proper care.

Aerobic Treatment Unit

Aerobic treatment units (ATUs) use oxygen to break down waste and treat the wastewater. This system is more complex than conventional septic systems and requires regular maintenance to keep it running efficiently. ATUs are suitable for properties with heavy water usage, as they can handle a large amount of wastewater. However, they are also more expensive to install and maintain.

Mound Systems

Mound systems are designed for properties with poor soil absorption capabilities. This system consists of a raised mound of sand and gravel that filters the wastewater as it flows through. Mound systems are more expensive than conventional systems and require regular maintenance to prevent clogging.

Recirculating Sand Filter System

Recirculating sand filter systems use a sand filter to treat wastewater, which is then recirculated back into the septic tank. This system is efficient as it filters the wastewater multiple times before it is released into the drain field. However, it requires regular maintenance to prevent clogging and can be costly to install.

Evapotranspiration System

Evapotranspiration systems use plants to absorb and evaporate wastewater. This system is suitable for properties with limited soil absorption capabilities and is environmentally friendly. However, it requires regular maintenance to keep the plants healthy and may not be suitable for all climates.

Constructed Wetland System

Constructed wetland systems are a natural and sustainable option for treating wastewater. This system consists of a series of shallow, planted pools that filter the wastewater as it flows through. The plants and microorganisms in the wetland help to break down the contaminants in the wastewater, making it safe for release into the environment. Constructed wetland systems are environmentally friendly and require minimal maintenance. They are also cost-effective and can be installed in both urban and rural areas.

Cluster/Community System

Cluster/community systems are designed for multiple properties to share a single septic system. This system consists of a large septic tank and a drain field that serves several properties. Cluster/community systems are ideal for areas where individual septic systems are not feasible due to space constraints or soil conditions. They are cost-effective and require less maintenance than individual septic systems. However, the system’s capacity must be carefully designed to ensure that it can handle the wastewater generated by all the properties it serves.


When choosing a septic system, it’s essential to consider factors such as the property’s location, soil conditions, and water usage. While city sewer systems are a convenient option, they may not be available in all areas, and the cost can be prohibitive. Constructed wetland systems and cluster/community systems are both sustainable and cost-effective options that can be tailored to meet the specific needs of a property. Ultimately, the best septic system will depend on the property’s unique requirements, and it’s essential to work with a qualified septic system installer to determine the best option for your property.
