Septic tank pump-outs for homes and businesses

A septic tank clean removes accumulated sludge and scum. We pump out the tank, clean it and check its visible condition, then remove the waste from your property. Tank size, use and access all affect the work involved, so we ask about your system before quoting.

Is your tank due for a clean?

Slow drains, persistent odours, sewage backing up and wet ground near the tank are reasons to have the system checked. A pump-out may be needed, but these symptoms can also have other causes. Describe what is happening when you call so we can discuss the next step. Our guide to septic warning signs explains what to look for.

Planning your next pump-out

The right interval depends on your tank, household use and service history. If you cannot find the last pump-out date, tell us when booking rather than guessing. See our guide to septic pump-out timing for the factors to consider.

Liftwells and AWTS units

A pumped system may also have a separate collection chamber that needs cleaning. Read about liftwell and pumping station cleaning. If your property has an aerated treatment unit, see AWTS cleaning and desludging so the correct service is booked.

Getting a quote

Call 0434 048 887 with your address, the type and size of the system, and a description of the problem. If you know when it was last cleaned, have that date handy. We will discuss access, agree on the work and confirm the price before starting.

Before the truck arrives

Tell us where the tank or pit is, how the truck can reach it, and whether there are gates, narrow driveways or other access limits. If you have system plans or previous service records, these can help us identify the right access point. Let us know about any other tanks or pits that need attention when you book.

Septic cleaning questions

Do I need to be home?

Discuss this when booking. We need clear directions to the tank and agreed access to the property; whether someone needs to be present depends on the site.

How long does a clean take?

The time depends on tank size, buildup and access. We can discuss an estimate once we know your setup.

Can you help with an urgent overflow?

Call our 24/7 line and describe the issue. We will confirm availability and the expected arrival time.
