Septic tanks play a vital role in managing household waste in Canada, particularly in areas where municipal sewage systems are not available. For beginners, understanding the key components of a septic system is essential to ensure proper maintenance and prevent potential issues. In this guide, we’ll unveil the fundamental aspects of septic tanks to help homeowners navigate the basics with confidence.

 The Anatomy of a Septic System

1. Septic Tank:

  • Purpose: The septic tank is the primary component designed to separate solids from liquids in household wastewater.
  • Material: Tanks are typically made of concrete, fibreglass, or plastic, providing durability and resistance to corrosion.
  • Location: Installed underground, septic tanks are commonly located in the backyard.

2. Inlet Pipe:

  • Function: Wastewater from the house enters the septic tank through the inlet pipe.
  • Separation Begins: As water flows into the tank, solids begin to settle at the bottom, forming sludge.

3. Outlet Pipe:

  • Filtered Effluent: The liquid portion of the wastewater, known as effluent, exits the septic tank through the outlet pipe.
  • Distribution: Effluent then travels to the drain field for further treatment.

4. Drain Field:

  • Absorption and Filtration: The drain field consists of perforated pipes or chambers buried in trenches filled with gravel. It allows effluent to be absorbed into the soil, undergoing natural filtration.
  • Role in Treatment: Soil microorganisms further treat the effluent, breaking down remaining contaminants.

 Maintenance Essentials for Septic Tanks

1. Regular Pumping:

  • Frequency: Schedule regular pumping every 3 to 5 years to remove accumulated sludge and prevent system overload.
  • Professional Assistance: Hire septic tank professionals for pumping to ensure proper disposal of waste.

2. Water Conservation:

  • Moderate Usage: Be mindful of water usage to prevent overloading the system.
  • Water-Efficient Fixtures: Install water-efficient appliances and fixtures to minimize water entering the septic tank.

3. Avoid Harsh Chemicals:

  • Septic-Safe Products: Use septic-safe cleaning products to maintain a healthy balance of bacteria in the tank.
  • Avoid Excessive Chemicals: Limit the use of harsh chemicals that can disrupt the natural processes within the tank.

4. Regular Inspections:

  • Professional Inspection: Periodically schedule inspections by septic tank professionals to identify potential issues.
  • Homeowner Inspection: Keep an eye out for signs of problems, such as foul odours, slow drains, or lush vegetation in the drain field.

 Common Septic Tank Issues

1. Clogs and Blockages:

  • Causes: Improper disposal of non-biodegradable items or excessive use of grease.
  • Prevention: Avoid flushing items like wipes, paper towels, or grease down the drains.

2. Overflow and Backups:

  • Causes: Neglecting regular pumping or excessive water usage.
  • Prevention: Schedule regular pumping and practice water conservation.

3. Drain Field Issues:

  • Causes: Soil compaction, root intrusion, or the use of the drain field for heavy activities.
  • Prevention: Avoid planting trees or shrubs near the drain field and refrain from driving or building structures on it.
