Above Ground vs. Underground Septic Systems
Choosing the right septic system is crucial for homeowners who live in areas without access to municipal sewer services. Two primary options are above ground and underground septic systems. Each has its own set of advantages and disadvantages, making it essential to understand both to determine which is right for you.
Above Ground Septic Systems
Above ground septic systems, often known as mound systems, are used in areas with high water tables, shallow soil, or poor soil conditions.
Advantages
- Suitable for Poor Soil Conditions: They are ideal for areas with rocky, clay, or sandy soil where traditional underground systems might fail.
- Elevated Drain Field: The elevated design helps prevent contamination of groundwater sources.
- Easier Access for Maintenance: Since the components are above ground, tasks like septic tank pumping and septic tank repair can be more straightforward and less invasive.
Disadvantages
- Higher Installation Costs: Due to the specialized design and materials required, the initial septic tank installation cost is generally higher.
- Aesthetic Concerns: The above-ground components can be visually unappealing, although landscaping can mitigate this issue.
- Potential for More Frequent Maintenance: Because of the unique setup, maintenance needs might be more frequent, requiring regular attention from a septic company.
Underground Septic Systems
Traditional underground septic systems are the most common choice for homes with suitable soil conditions. These systems consist of a septic tank buried underground, with a drain field that disperses treated water.
Advantages
- Lower Installation Costs: These systems typically cost less to install compared to above ground systems.
- Aesthetics: Since the components are buried, they do not affect the landscape’s appearance.
- Proven Technology: Underground systems are well-established, with many septic companies familiar with their installation and maintenance.
Disadvantages
- Soil Requirements: They require suitable soil conditions for effective operation. Poor soil can lead to system failure.
- Accessibility for Maintenance: Septic tank pumping, repair, and cleaning can be more challenging due to the buried components.
- Risk of Groundwater Contamination: In areas with high water tables or poor drainage, there is a risk of contamination if the system is not properly maintained.
Maintenance Considerations
Regardless of the type of system you choose, regular maintenance is essential to ensure its longevity and functionality.
- Regular Pumping: Septic tank pumping should be done every 3-5 years, depending on the size of the tank and household usage. This prevents solids from building up and clogging the system.
- Inspections: Regular inspections by Rooter Septic Services can identify issues before they become serious problems, reducing the need for extensive septic tank repair.
- Proper Use: Avoid flushing non-biodegradable items or pouring grease down the drain to prevent clogs and reduce the need for frequent septic tank cleaning.
Choosing the Right System
When deciding between an above ground and underground septic system, consider the following factors.
- Soil Conditions: Conduct a soil test to determine which system is most suitable for your property.
- Budget: Consider both the initial septic tank installation cost and long-term maintenance expenses.
- Aesthetics: Decide if the visual impact of an above ground system is acceptable or if a hidden underground system is preferable.
- Local Regulations: Check local health department regulations and requirements, as they can influence your choice.
Choosing between an above ground and underground septic system depends on your property’s specific conditions and your personal preferences. Both systems have their benefits and drawbacks, and consulting with a professional septic company like Rooter Septic Services can help you make an informed decision.
