• Skill level: 4 / 5 (requires specialised knowledge in hydraulics and waste management as well as confined space working experience).

• Typical duration: Several hours up to a full day, varying with the severity of the fault and tank condition.

Safety First

• Always wear full personal protective equipment, including gloves, boots and eye protection.

• Ensure proper ventilation when working in confined spaces and consider a safety harness if required.

• Use adequate signage and barrier protection to secure the work area.

• Handle any chemical treatments with care and in accordance with manufacturer guidelines.

Tools & Materials

Step-by-Step

1. Inspect the septic tank – assess condition, leaks, blockages and structural damage.

2. Isolate the system – safely disconnect inflow and outflow to avoid contamination.

3. Pump out the tank – remove excess sludge and waste to reduce hazards during repair.

4. Identify faults – use inspection tools to locate cracks, blockages or broken components.

5. Carry out repairs – patch cracks, replace damaged parts or clear blockages as required.

6. Test the system – check for proper flow, leak absence and ensure all repairs meet safety standards.

7. Restore and finalise – clean the area, reconnect the system and document the work completed.

Completion Checks

• Septic tank is leak-free and structurally sound.

• Flow and drainage have been fully restored.

• All repairs comply with local health and environmental regulations.

• A final system test confirms safe and efficient operation.

When to Call a Pro Instead

For issues involving extensive structural damage, persistent malfunctions, or where legal compliance and safety certifications are required, calling a certified septic tank repair specialist is highly recommended.
