Differences Between Conventional and Aerobic Septic Systems

Differences Between Conventional and Aerobic Septic Systems

When dealing with waste management for your home, understanding the difference between aerobic and conventional septic systems is crucial. Each has pros and cons, and knowing these can help you make the best choice for your needs. In this guide, Metro Septic Pumping explains how these two systems compare and when you might need to call a septic company for services like septic tank pumping.

What is a Conventional Septic System?

A conventional septic system is the most common type found in homes. It typically consists of a septic tank and a drain field. Wastewater from your house flows into the septic tank, where solids settle to the bottom, and liquids flow out into the drain field for further treatment in the soil.

Key Components:

• Septic Tank: This is where the initial separation of solid waste and liquid takes place.
• Drain Field: Also known as a leach field, this area allows the liquid to seep into the ground, where it's naturally filtered and treated by soil microorganisms.

Over time, solids accumulate in the septic tank, necessitating periodic septic tank pumping. A septic company will perform this service to prevent the tank from overflowing and causing a backup.

What is an Aerobic Septic System?

On the other hand, an aerobic septic system uses oxygen to help break down and treat wastewater. This more complex system includes additional components like an aerator and disinfectant chamber. The process involves treating the waste with oxygen to speed up the decomposition of organic matter.

Key Components

• Aerator: This device adds oxygen to the wastewater, promoting the growth of aerobic bacteria that break down waste more efficiently.
• Disinfectant Chamber: This chamber ensures that the treated water is disinfected before being released into the drain field or surface water.

Because of its complexity, an aerobic system often requires more frequent maintenance. A septic company must regularly clean and inspect the tank to ensure proper functioning.

Comparison of Treatment Processes

• Treatment Efficiency: Aerobic systems typically provide a higher treatment level than conventional systems. This is because the aerobic bacteria used in the process break down waste more completely.
• Environmental Impact: Aerobic systems are better suited for areas with high water tables or poor soil conditions because they treat wastewater more thoroughly before it's released.
• Cost: Conventional systems are generally less expensive to install and maintain. However, aerobic systems can save money in the long run by extending the life of the drain field and reducing the frequency of septic tank repair.

Maintenance and Costs

Maintaining your septic system is crucial to its longevity and efficiency. Both systems require regular septic tank pumping, but the frequency can vary. Conventional systems usually need pumping every 3-5 years, while aerobic systems may need more frequent attention.

• Septic Tank Pumping: Regular pumping prevents the buildup of solids that can clog the system and cause backups. A septic company can provide this service and check for any signs of needed septic tank repair.
• Septic Tank Cleaning: Aerobic systems often need frequent cleaning and inspections to ensure the aerator and other components function correctly.

While aerobic systems might have higher maintenance costs, their ability to treat wastewater more thoroughly can result in fewer environmental impacts and potentially lower long-term costs.

Installation Considerations

When considering septic tank installation, it is important to evaluate your property's soil conditions, water table level, and local regulations. Conventional systems are easier and cheaper to install in areas with well-draining soil. However, an aerobic system might be the better choice if your property has poor soil conditions or a high water table despite the higher upfront cost.

A professional septic company can assess your site and recommend the best type of system for your needs. They can also handle the septic tank installation, ensuring it's done correctly and complies with local regulations.

Making the Right Choice

Choosing between an aerobic and a conventional septic system depends on various factors, including your budget, property conditions, and environmental concerns. Here are some key points to consider:

• Budget: Conventional systems are typically cheaper to install and maintain. However, aerobic systems might offer long-term savings through better wastewater treatment and fewer septic tank repairs.
• Environmental Impact: If you're concerned about the environment and live in challenging soil conditions, an aerobic system might be worth the extra investment.
• Maintenance Needs: Consider how often you're willing to schedule septic tank pumping and cleaning. Aerobic systems require more frequent maintenance but offer superior treatment.
