Understanding Above Ground Septic Tanks
Above ground septic tanks are an essential component of wastewater management systems, particularly in areas where traditional underground septic systems are impractical or impossible to install. These tanks serve the same fundamental purpose as their underground counterparts: to treat and manage sewage and wastewater from residential or commercial properties. However, their above-ground design offers unique advantages and challenges that are worth exploring.
The primary function of an above ground septic tank is to collect and treat wastewater before it is released into the environment. This process is crucial for preventing pollution and protecting public health. Unlike conventional septic systems that rely on gravity to move waste through a series of underground pipes and soil filtration, above ground tanks use a different approach. They are typically made from durable materials such as fiberglass, plastic, or concrete, designed to withstand the elements and provide a reliable solution for waste management.
One of the most significant advantages of above ground septic tanks is their ease of installation. In situations where the soil is too rocky, sandy, or saturated to support a traditional system, above ground tanks can be placed on the surface, eliminating the need for extensive excavation. This can save time and money during installation, making them an attractive option for homeowners and builders alike.
However, the use of above ground septic tanks is not without its challenges. They require careful maintenance and monitoring to ensure they function correctly. Because they are exposed to the elements, they can be susceptible to damage from weather conditions, pests, and other environmental factors. Additionally, local regulations may impose restrictions on their use, requiring homeowners to adhere to specific guidelines to ensure safety and compliance.
In this article, we will delve deeper into the workings of above ground septic tanks, exploring their components, how they function, and the benefits and drawbacks associated with their use. We’ll also provide practical recommendations for homeowners considering this option for their wastewater management needs.

How Above Ground Septic Tanks Operate
Above ground septic tanks are designed to manage wastewater effectively, ensuring that harmful contaminants are treated before being released into the environment. Understanding how these systems work is crucial for homeowners and property managers who rely on them. This section will break down the components of above ground septic tanks, their operational processes, and the factors that influence their efficiency.
Components of Above Ground Septic Tanks
An above ground septic tank consists of several key components that work together to treat wastewater. These components include:
- Tank Body: The main structure, often made from fiberglass, plastic, or concrete, that holds the wastewater.
- Inlet Pipe: This pipe connects the home’s plumbing to the tank, allowing wastewater to flow into it.
- Outlet Pipe: This pipe carries treated effluent from the tank to the drain field or other disposal area.
- Access Ports: These openings allow for maintenance and inspection of the tank.
- Effluent Filter: A device that prevents solids from exiting the tank and clogging the drain field.
Operational Process of Above Ground Septic Tanks
The operation of an above ground septic tank can be broken down into several stages:
- Wastewater Inflow: Wastewater from the home enters the tank through the inlet pipe. This includes water from sinks, showers, toilets, and appliances.
- Sedimentation: Once inside the tank, the wastewater undergoes sedimentation. Heavier solids settle at the bottom, forming sludge, while lighter materials, such as grease and oils, float to the top, creating scum.
- Aerobic Treatment: Some above ground septic tanks incorporate aerobic treatment systems that introduce oxygen into the tank. This process helps break down organic matter more efficiently than anaerobic systems.
- Effluent Discharge: After sufficient treatment, the liquid effluent flows through the outlet pipe to the drain field or other designated disposal area. Here, it undergoes further filtration and treatment as it percolates through the soil.
Benefits of Above Ground Septic Tanks
Above ground septic tanks offer several advantages over traditional underground systems:
- Installation Flexibility: They can be installed in areas where soil conditions are unsuitable for traditional systems.
- Cost-Effective: Reduced excavation and site preparation can lower installation costs.
- Accessibility: Easier access for maintenance and inspections can lead to better long-term performance.
- Environmental Protection: Properly maintained systems help prevent groundwater contamination.
Challenges and Considerations
While above ground septic tanks have their benefits, they also come with challenges that need to be addressed:
- Weather Vulnerability: Exposure to the elements can lead to damage from extreme weather conditions, such as heavy rain or freezing temperatures.
- Maintenance Requirements: Regular pumping and inspections are necessary to ensure optimal performance and prevent system failure.
- Local Regulations: Homeowners must comply with local health and safety regulations, which may dictate specific requirements for installation and maintenance.
Understanding the workings of above ground septic tanks is essential for effective wastewater management. By recognizing their components, operational processes, benefits, and challenges, homeowners can make informed decisions about their wastewater treatment options.
Practical Recommendations for Above Ground Septic Tank Management
Maintaining an above ground septic tank is crucial for ensuring its longevity and effectiveness in wastewater treatment. Proper management not only protects the environment but also enhances the system’s performance. Here are actionable recommendations for homeowners and property managers.
Regular Maintenance Schedule
Establishing a maintenance schedule is essential for the optimal functioning of your above ground septic tank. Consider the following steps:
- Schedule regular inspections at least once a year.
- Have the tank pumped every 3 to 5 years, depending on usage and tank size.
- Check for signs of leaks or damage during inspections.
What to Look For During Inspections
During your inspections, be vigilant for the following issues:
- Cracks or damage to the tank body.
- Unpleasant odors around the tank area.
- Pooling water or soggy ground near the drain field.
- Clogged effluent filters.
Proper Waste Disposal Practices
The way you dispose of waste can significantly impact the performance of your septic system. Follow these guidelines:
- Avoid flushing non-biodegradable items such as wipes, sanitary products, and plastics.
- Limit the use of harsh chemicals that can disrupt the bacterial balance in the tank.
- Be cautious with food waste disposal; consider using a composting system for organic materials.
Water Usage Management
Managing water usage can help prevent overloading the septic system. Here are some tips:
- Install water-efficient fixtures, such as low-flow toilets and faucets.
- Spread out laundry and dishwashing over the week instead of doing it all in one day.
- Fix leaks promptly to avoid unnecessary water accumulation.
Understanding Your System’s Capacity
Knowing the capacity of your septic tank is vital. Here’s how to gauge it:
- Consult the tank specifications to understand its volume.
- Keep track of the number of occupants in your home, as this affects wastewater production.
- Adjust your water usage based on the number of people using the system.
Environmental Considerations
Protecting the environment should be a priority when managing your septic system. Consider these actions:
- Plant grass or shallow-rooted plants around the tank and drain field to prevent soil erosion.
- Avoid parking vehicles or placing heavy objects on top of the septic tank.
- Keep chemicals, oils, and other hazardous materials away from the tank and drain field.
Emergency Preparedness
Being prepared for emergencies can save you time and money. Here’s what to do:
- Know the location of your septic tank and drain field.
- Have a list of emergency contacts, including a local septic service provider.
- Keep a maintenance log that includes inspection dates, pumping dates, and any repairs made.
Emergency Signs to Watch For
Be aware of the following signs that indicate potential problems:
- Slow drains in your home.
- Unpleasant odors near the septic tank or drain field.
