Frequently Asked Questions

Service & Maintenance

How often should I pump out my septic tank?

In accordance with Australian Standards and local council health regulations, most septic tanks should be pumped out every 3 to 5 years. This frequency depends on the size of your tank and the number of people in your household or business.

Common indicators that your tank requires servicing include:

  • Slow-draining sinks, tubs, or toilets.
  • Gurgling sounds in the plumbing system.
  • Persistent sewage odours.
  • Patches of unusually lush, green grass or pooling water near the absorption trenches.

If sludge is left to accumulate, it can overflow into your absorption trenches (soakage area). This leads to soil clogging, system failure, and potential environmental contamination. Repairing or replacing a failed absorption area can cost thousands of dollars, whereas regular pumping is a fraction of that cost.

You do not need to stop using water before we arrive. Once the pump-out is complete, you can resume normal water usage immediately.

To maintain a healthy system:

  • Avoid flushing “flushable” wipes, feminine hygiene products, or paper towels.
  • Limit the use of harsh bleach or chemical cleaners that kill beneficial bacteria.
  • Keep heavy vehicles or livestock off the absorption area to prevent soil compaction and pipe damage.

Pricing & Logistics

The cost is determined by the volume of waste (measured in litres) and your location. Because disposal fees vary by council and waste type, we provide obligation-free quotes to ensure you receive a fair and accurate price.

The primary factors include:

  • Tank Capacity: Larger tanks take longer to pump and incur higher disposal fees.
  • Location: Travel distance to your property and the nearest licensed disposal facility.
  • Access: If the tank is located a significant distance from where our truck can safely park, additional hose lengths may be required.

Yes. Emergency after-hours call-outs or sites requiring more than 50 metres of hose may incur additional charges. We recommend discussing your site layout with our team when booking.

No, you do not need to be there as long as our operators have clear, unobstructed access to the tank and any gates are unlocked.

Yes. To keep service costs down, we ask that you locate and uncover the tank lid before we arrive. If you are unable to find the lid, our operators can assist in locating it using specialised equipment for an additional fee.

Technical & Environmental

Our vacuum truck operator inserts a high-suction hose into the tank to extract the accumulated sludge, scum, and liquid effluent. We ensure the tank is thoroughly emptied and then securely replace the lid.

While the tank is empty, our operators perform a basic visual inspection. We look for obvious signs of structural damage, such as cracks in the concrete or damaged baffles, and will notify you if we identify any issues that require attention.

Absolutely. Enwaste is fully licenced by the Department of Environment and Science (DES). All waste is transported and discharged at EPA-approved treatment facilities where it is processed according to strict environmental guidelines.

Yes. During periods of heavy rain, the soil in your absorption trenches can become saturated, preventing the tank from draining. This can cause your system to back up even if the tank is not full of solid waste.

If you have recently had a pump-out but are still experiencing slow drains or sewage smells, your absorption trenches may have failed. Our team can help diagnose whether the issue is a simple blockage or a more serious system failure.

Emergency Situations

We maintain a fleet of trucks across South East Queensland and prioritise emergency requests where there is a risk of environmental contamination or property damage.

  1. Stop using all water immediately (do not flush toilets or run taps).
  2. Check if the overflow relief gully (ORG) outside is clear.
  3. Call Enwaste immediately to arrange an emergency pump-out to prevent further internal damage.
