Understanding Septic Tank Options
After recognizing the importance of selecting the right septic tank, learning about the specifics of the available options is essential. Each type of septic tank has distinct characteristics that can significantly impact its performance and suitability for your property. Understanding their characteristics, advantages, and drawbacks will help you make well-informed decisions about your wastewater treatment needs.
Plastic Septic Tanks (Poly Septic Tanks)
Plastic septic tanks, known for their light weight and ease of installation, are popular among homeowners. They offer quick and cost-effective setups, reducing labour expenses and time. These tanks are made from durable polyethylene, which provides excellent resistance to corrosion and is easier to handle than traditional materials.
Advantages
- Cost-Effective: Generally cheaper than concrete options.
- Lightweight: Simplifies installation with fewer labour requirements.
- Portable: Easy to relocate and position in various locations.
- Corrosion-Resistant: Immune to rust or water degradation.
- Flexible: Less likely to crack under pressure due to material flexibility.
- Hygienic: Easier to keep clean compared to concrete tanks.
- Pre-Assembled: Ready for quick and straightforward installation.
- Low Maintenance: Smooth surfaces make cleaning easier.
Disadvantages
- Less Durable: May deform under heavy soil or vehicular pressure.
- Environmentally Sensitive: Prone to ruptures or breaks due to soil vibrations and temperature changes.
- More Vulnerable: Susceptible to damage and warping.
- Frequent Maintenance: Requires more regular inspections and upkeep.
- Limited Lifespan: Often shorter than that of concrete tanks.
- Buoyancy Issues: Risk of shifting if not anchored properly.
- Regulatory Approval: Only permitted in some states due to varying regulations.
Concrete Septic Tanks
Concrete septic tanks are a time-tested option for those seeking strength and longevity. Made from precast concrete and reinforced with steel rebar, their durability and capacity to withstand heavy loads make them ideal for large properties or high-demand situations.
Advantages
- Durable & Long-Lasting: Can last up to 40 years with proper maintenance.
- Less Likely to Leak: Concrete tanks are less likely to leak than plastic, reducing inspection needs.
- Stable Underground Placement: Their heavy weight prevents floating, even under substantial soil or vehicle pressure.
- More Resistant to Freezing: Ideal for cold climates, concrete tanks are less likely to freeze compared to plastic tanks.
- High Effluent Capacity: Ideal for larger households or high-volume waste.
- Handles Heavy Loads: Capable of withstanding the pressure from heavy soil and vehicles without sustaining damage.
Disadvantages
- Heavy & Complex Installation: Requires machinery for placement, increasing installation complexity and cost.
- Prone to Cracking: Potential for leaks if not maintained.
- Corrosive Risks: Susceptible to chemical attack over time.
- Expensive Repairs: Repairing a damaged concrete tank can be difficult and costly.
Finding the Perfect Septic Tank for Your Home
Choosing the right septic tank involves considering various factors impacting its performance, longevity, and compatibility with your property. Below, we break down key considerations to help you decide between concrete and plastic septic tanks, ensuring you select a system that meets your needs.
Factors to Consider
1. Budget
The cost of septic tanks can vary significantly between concrete and plastic options. While plastic tanks generally have a lower initial purchase price and reduced installation costs, concrete tanks, though initially more expensive, may offer greater value over time due to their longevity and reduced maintenance needs. Evaluating your budget will help you determine which option is more cost-effective in the long run. For a comprehensive cost analysis, consider requesting a free quote.
2. Wastewater Volume
The amount of waste water your household produces daily should guide your choice of tank material. Concrete tanks typically have higher effluent capacities and are better suited for large households or those with high wastewater output. In contrast, plastic tanks are available in various sizes but may require more frequent emptying and maintenance if under heavy use.
3. Ease of Installation
Consider the installation process when choosing your tank. Plastic tanks are lighter and often more flexible to install, which can significantly reduce labour and equipment costs. On the other hand, concrete tanks are heavier and require more rigorous installation procedures, which might be a critical factor if access to your property is restricted.
4. Durability Needs
Durability is a major factor in selecting a septic tank. Concrete tanks are highly durable and resistant to various environmental factors, making them suitable for areas with high traffic or heavy soil. Plastic tanks, while durable in their own right, can be susceptible to damage from external pressures and may not last as long as their concrete counterparts without proper maintenance.
5. Soil and Site Conditions
The specific conditions of your site, such as soil type and water table level, can influence the performance of your septic tank. Plastic tanks, being lighter, might require additional anchoring in high-water table areas to prevent flotation. Due to their weight, concrete tanks naturally resist buoyancy and are typically more stable in varied soil conditions.
6. Long-Term Maintenance
Maintenance considerations are vital in your decision. Concrete tanks often require less frequent maintenance but can be more challenging and costly if issues arise. Plastic tanks are generally easier to install and maintain but might need more regular checks to ensure integrity, especially in environments with fluctuating temperatures and moisture levels.
7. Regulations and Permits
Local regulations and permits can dictate tank choice. Check with authorities on permissible tank types and applicable installation/maintenance rules. The Queensland Development Code (MP 4.2 and MP 4.3) requires features like mosquito-proof screens and lead-free materials to ensure safety. Regular inspections by local authorities are also necessary to verify compliance with these standards.

How much does a septic tank weigh?
Septic tank weight varies by material and size. Concrete tanks can weigh several tonnes, while plastic tanks are much lighter, often weighing less than 500 kilograms.
Is a concrete or plastic septic tank better?
The choice depends on your specific needs—concrete tanks are for durability and longevity, while plastic tanks are for cost efficiency and easier installation.
What kind of septic tank lasts the longest?
Concrete septic tanks generally have the longest lifespan, often lasting up to 40 years or more with proper maintenance. Although they can be more expensive and challenging to install, their durability and strong construction make them a worthwhile investment.
What is the life expectancy of a plastic septic tank?
The life expectancy of a plastic septic tank is about 30 years or a bit more with proper maintenance. Their lifespan depends on factors like soil conditions and usage.
