Request an AWTS cleanout

Aerated wastewater treatment system (AWTS) cleanouts are recommended every 5 years to ensure the ongoing working of a system is maintained.

If a tank is not cleaned out, a layer of sludge will settle on the bottom of the tank that will cause blockages or prevent the transfer of solids to your effluent disposal area (e.g. trenches or collection tank).

Tank cleanouts are a pre-paid service and include:

  • Standard cleanouts - undertaken within three (3) working days
  • Emergency cleanouts - actioned within 24 hours (additional fees apply)

Please note: If the tank is greater than 8,000L or a non-standard tank, you will be invoiced for the service.
