Key Aspects Of Septic Tank Installation: A Comprehensive Guide

By Graham’s Precast Concrete Products Pty Ltd


Installing a septic tank is a detailed procedure that demands an understanding of various aspects. It’s a decision that not only impacts the daily functioning of a household but has long-term implications for the environment and property value. Here’s a comprehensive look into these aspects to help you make a sound decision.

Determining the Right Size for Your Needs

Size is of utmost importance when it comes to septic tanks. The tank’s capacity will determine how efficiently it processes waste and how often it needs maintenance. Household size estimated daily water usage and property dimensions play an important role in determining the ideal tank size. For instance, a small family might suffice with a smaller tank, while larger households or properties with frequent guests might need more substantial systems. Manufacturers are well-versed in calculating the optimal size based on these variables, ensuring that the tank serves its purpose efficiently over the years.

Material Choices: Durability and Functionality

  • Concrete: One of the oldest materials used, concrete tanks boast of longevity. While they are durable and can last for decades, they are heavy, often requiring specialised equipment and techniques for installation.
  • Fiberglass: A modern alternative to concrete, fiberglass tanks are lighter, thus easier to install. Their resistance to rust and corrosion makes them an appealing choice. However, care must be taken during installation as they can be susceptible to damage.
  • Plastic (Polyethylene): Their primary advantage is their lightweight nature, making transport and installation a breeze. They’re rust-proof but might not offer the same lifespan as concrete.

Local Regulations and Compliance

Septic tanks must adhere to strict Australian standards that guarantee both environmental safety and the safety of those residing on the property.

  • Permit Acquisition: Most regions require homeowners to acquire a permit before installing a septic system. Qualified installers can often assist in navigating this bureaucratic step, ensuring all paperwork is in order.
  • Inspection Protocols: After installation, several councils demand an official inspection. This step guarantees that the installation aligns with all local requirements and that the system operates safely.

Site Assessment and Pre-installation Steps

An effective septic tank installation begins much before the actual process. A thorough site assessment ensures that the system is placed optimally. This involves studying the soil type, which affects drainage and absorption rates. The water table depth and land gradient are other factors taken into consideration. An installer will also look for potential obstructions and access paths to ensure smooth installation.

Efficiency and Environmental Considerations

  • Reduced Water Consumption: Advanced septic systems often incorporate features that aid in reducing overall water consumption, directly contributing to global sustainability efforts.
  • Eco-friendly Materials: Innovations have led to the development of tanks made of recycled or eco-friendly materials, marking a stride in the industry’s environmental responsibility.
  • Natural Filtration Systems: Some modern systems integrate natural filtration processes, allowing for cleaner water output, which further minimises environmental impact.

Understanding the Maintenance Schedule

A well-maintained septic system can serve a household efficiently for many years. Scheduled checks, usually every 3-5 years, ensure the system’s smooth operation. During these checks, accumulated sludge is pumped out. Manufacturers provide homeowners with a detailed manual that outlines maintenance routines, signs of potential issues and recommendations for optimal system performance.

Post-installation Support and Warranties

The responsibility of a manufacturer doesn’t end with installation. Ensuring the system’s long-term operation often involves periodic checks, repairs and part replacements. Having a warranty not only assures homeowners about the product’s quality but provides a safety net against unforeseen issues.

Cost Implications and Financing Options

A septic tank is a long-term investment. While the initial cost might seem significant, it’s crucial to factor in long-term savings from reduced water bills and potential damages from malfunctioning systems. To ease the financial burden, some manufacturers extend financing options, making high-quality septic systems accessible to a broader audience.

The Evolution of Septic Systems: Modern Innovations

  • Advanced Filters: Contemporary septic tanks have evolved to include sophisticated filtration mechanisms. These advanced systems not only improve the purity level of the processed wastewater but also prolong the life of the drain field.
  • Remote Monitoring: Integration of digital technology with septic tanks allows for remote monitoring of system health. Homeowners can now receive real-time data and notifications on potential issues, reducing the risk of major malfunctions and costly repairs.
  • Improved Lifespan: Continuous research and development in the industry have birthed septic tanks with considerably enhanced lifespans. These modern tanks not only promise a longer functional life but also offer a more efficient, environmentally friendly operation over the years.
