Wastewater Expert’s Step-by-Step Guide to Septic Tank Installation

Septic Tank Installation by a Technician

Living in rural areas necessitates effective wastewater management. A strong understanding of septic systems simplifies this process, making it achievable. This guide provides a step-by-step approach to septic tank installation. It highlights how it promotes a healthier lifestyle and contributes to a cleaner environment. Whether new to septic systems or looking to upgrade your current setup, this guide delivers valuable insights and practical steps for sustainable wastewater management.

Understanding the Septic Tank System

The septic tank system is integral for treating wastewater in regions lacking municipal sewage services. It utilises a tank where waste decomposes with the help of bacteria. The treated liquid effluent then flows into a drain field for further purification. This system is vital for managing household wastewater and protecting the environment. Regular maintenance is necessary for its longevity and efficacy.

Assessing Your Property for a Septic Tank

Proper property assessment is the first step towards a successful septic tank installation. The evaluation includes soil testing, percolation tests, securing necessary permits, and ensuring the system design complies with local septic tank installment requirements.

1. Soil Testing and Site Evaluation

Soil testing and site evaluation are critical in determining your property’s most suitable septic system. These initial steps help evaluate the soil’s water absorption capabilities, which influence the size of your leach field. Ideal soils for septic tanks include: 

  • Sandy or loamy soils
  • Soil with a balanced mix of gravel and clay 

During the site evaluation, consider the layout, slope, and proximity to water sources to ensure compliance with septic tank regulations and avoid areas with high water tables and steep slopes. 

Percolation Tests

A percolation or perc test measures the rate at which soil absorbs water, which is important for designing the leach field. This test is essential for environmental protection and compliance with local regulations. It involves:

  • Digging small holes.
  • Saturating the soil with water.
  • Measuring the water absorption rate.

Submitting the perc test results to the local council before the septic system installation is mandatory.

2. Securing Necessary Permits

Securing necessary permits is crucial. This process involves submitting detailed system designs and soil test results to local health or environmental authorities. The permit ensures your septic tank installation meets all regulatory requirements and avoids unexpected legal complications.

Choosing the Right Septic Tank

Choosing the right septic tank requires understanding the different types available and considering size and capacity based on your needs.

1. Types of Septic Tanks

Concrete:

These tanks are renowned for their durability and longevity. While sturdy and long-lasting, they are also heavy and challenging to install.

Fibreglass:

Fibreglass tanks offer a lightweight alternative to concrete. They are corrosion-resistant, making them ideal for long-term use, and they are relatively easy to install compared to concrete tanks.

Plastic:

Plastic tanks are lightweight and resistant to cracking. However, they may not be as durable as concrete or fibreglass options. Despite this, people often choose plastic tanks for their ease of installation and lower cost.

2. Size and Capacity Considerations

The right size and capacity of your septic tank depend on:

Size of the Household:

Larger households generate more wastewater, necessitating a larger tank.

Land Area:

The available land space influences the system’s layout and size. Considering local regulations and setbacks, sufficient tank and drain field space is essential.

Soil Absorption Capacity:

Assessed through percolation tests to determine the appropriate tank size.

Step-by-Step Process for the Septic Tank Installation

Proper planning and execution are essential for a successful septic tank installation. Here’s what the process involves:

1. Preparing the Site

  • Site Evaluation: Assess the soil and groundwater conditions.
  • Planning and Permits: Obtain necessary permits based on the design.
  • Marking the Location: Clearly define where you will install each component.
  • Site Clearing: Remove any obstructions from the installation area.
  • Excavation: Follow the design plans to prepare the site.

2. Installing the Tank

  • Tank Delivery: Ensure the tank is delivered safely to the site.
  • Positioning the Tank: Place the tank precisely in the designated area.
  • Stabilising the Tank: Secure the tank by backfilling around it.

Careful handling and precise placement are crucial to ensure the tank functions correctly and remains secure.

3. Installing Septic Pipes and the Drain Field

  • Connecting Pipes: Install and connect the inlet and outlet pipes.
  • Positioning the Distribution Box: Set up the distribution box correctly.
  • Laying Drain Field Pipes: Ensure the pipes are correctly laid and covered.

Proper installation ensures efficient wastewater distribution and absorption.

4. Backfilling and Landscaping

  • Backfilling: Fill in the excavated areas properly.
  • Grading: Adjust the terrain to ensure proper drainage.
  • Landscaping: Use vegetation to prevent erosion and beautify the area.

This procedure ensures proper drainage and covers the area with vegetation to prevent erosion.

5. Finalising the System

Complete the installation by ensuring everything functions as designed:

  • Inspection: Conduct a final inspection.
  • System Testing: Check for proper operation.
  • Documentation: Maintain records of installation and maintenance guidelines.
  • Maintenance and Monitoring: Set up a regular maintenance schedule.

Safety Considerations During Installation

When installing a septic tank, adhering to safety protocols is crucial to prevent accidents and ensure compliance with regulations. Here are the key safety measures:

  • Excavation Safety: Use proper trenching techniques to prevent cave-ins and continually monitor soil stability.
  • Handling Heavy Equipment: Utlise lifting equipment operated by trained personnel to ensure safe handling.
  • Personal Protective Equipment (PPE): Always wear essential safety gear, including hard hats, safety glasses, gloves, high-visibility clothing, and steel-toed boots.
  • Confined Space Safety: Maintain proper ventilation, utilise gas detectors, and have a strong rescue plan and emergency communication devices.
  • Utility Safety: Before excavation, accurately Identify and label underground utilities to avoid disruptions.
  • Installation Procedures: Install the tank on a stable, level base, ensuring correct alignment and sealing of the inlet and outlet pipes.
  • Environmental Protection: Implement measures to minimise soil and water contamination during installation.
  • Regulatory Compliance: Secure all necessary permits and adhere to all regulations. Schedule required inspections to ensure regulatory compliance.

Common Installation Mistakes to Avoid

When installing a septic tank, avoiding common pitfalls is essential for ensuring long-term functionality and preventing costly repairs. Here are key mistakes to steer clear of:

  • Impact and Sharp Edges: Avoid impacting the tank or placing it near sharp objects that could puncture or damage it.
  • Improper Modifications: Adding neck extensions to the tank or building a brick maintenance hole above the tank neck increases burial depth and can lead to installation complications.
  • Excessive Burial Depth: Do not install the tank deeper than its designed depth, as this can jeopardize its structural integrity.
  • Installation in High Traffic Areas: Installing the tank in areas that will bear heavy loads (like trafficked or sloped areas) without proper backfill design can damage the tank.
  • Incorrect Backfilling Practices: Never backfill around an empty tank; it can lead to uneven settling or structural damage.

Long-term Maintenance Costs

Maintaining a septic system involves ongoing costs that are essential for its longevity and efficiency:

  • Regular Pumping: Septic tanks should be pumped every 2 to 5 years to remove solids buildup. The frequency and cost of pumping depend on the tank size and household wastewater volumes.
  • Potential Repair Costs: Over time, wear and tear, accidental damage, or system failures may necessitate repairs. The costs for these repairs can vary greatly, depending on the extent of the damage and the parts of the system affected.
