FAQ

Frequently Asked Septic System Services Questions

Answers to common questions about our Septic System Services

Is Your Septic Tank Causing Problems? Know The Warning Signs

It's important to recognise the early signs of a septic tank issue before it becomes a major crisis. If you notice any of the following, it's time to contact our team for professional advice:

  • Foul Odours: Unpleasant smells around the tank, drainage field (soakaway), or even back inside your property are a classic sign of a blockage or full tank.
  • Slow Drains: Are your toilets, sinks, and showers draining much slower than usual? This indicates the system is struggling to cope.
  • Gurgling Sounds: If you hear strange gurgling noises from your pipework, it’s often caused by trapped air from a blockage in the system.
  • Waterlogged Ground: Spongy, unusually green grass or standing water near your septic tank or soakaway area suggests the system is overflowing and not draining correctly.

How Often Does My Septic Tank Need Professional Cleaning and Maintenance?

Regular, professional cleaning (often called de-sludging) is the single most important thing you can do to keep your septic tank working properly and avoid costly repairs. As a general rule, most domestic septic tanks need to be emptied every 12 to 18 months. However, this can vary depending on the size of your tank and the number of people living in your home. Regular maintenance helps prevent the build-up of solids that can block your soakaway system, which can be very expensive to repair or replace. Our team can advise on the perfect maintenance schedule for your specific needs.

Septic Tank or Treatment Plant: Which System Do I Need?

This is a common question, especially for those planning a new build or needing to upgrade an older system. A septic tank is a relatively simple holding tank where solids settle at the bottom and wastewater flows out into a soakaway system to be filtered naturally by the soil. A wastewater treatment plant is a more advanced solution. It uses mechanical parts and bacteria to actively treat the water, producing a much cleaner effluent. Treatment plants are often required if you need to discharge near a watercourse or if the ground conditions are not suitable for a traditional soakaway. We can conduct the necessary percolation tests and provide expert advice on the right solution for your property.

Looking for a New Septic Tank Installation? We Can Help.

Absolutely. Our team is able to diagnose and repair all manner of septic tank problems.
