What happens on the day

What actually happens on the day.

You get a person, not a queue

Ring and someone who drives the truck answers. You get a price and a day on that call, not a callback.

Finding it is part of the job

Under the lawn, under a garden bed, under a slab someone poured over it. We locate the lid and uncover it before anything else.

Emptied properly, not skimmed

A tank is not done when the liquid is gone. The crust and the settled sludge come out too, which is the part that decides how long before you need us again.

The paperwork follows the load

Tipped at a licensed facility, recorded, and available to you if a council or a buyer ever asks where it went.

The council report is handled

Treatment systems come with paperwork obligations. We do the service and the report together, so nothing is chased later.

The lid goes back properly

Seated, weighted, and safe to walk over. That last part matters more than anything else on this list.

Not the same as the next truck

Straight answers

The questions we get asked most.

How often should a septic tank be pumped?
For most households it is every three to five years, and it depends on tank size and how many people live there. If it has been longer than five years, or you have just moved in and nobody can tell you when it was last done, book it.
How do I know if mine needs doing?
Slow drains through the whole house, gurgling, a smell near the tank, or wet ground and greener grass over the trench. Any of those means ring, do not wait.
Do you need to find the lid, or do I?
We can find it. If you know where it is, tell us and we are faster. If nobody has looked in twenty years, that is a normal job for us.
Can the truck get to my tank?
Usually. Tell us if the tank is behind a locked gate, down a steep drive, or more than about thirty metres from where a truck can park, and we will bring the right hose.
What happens to the waste?
It goes to a licensed facility and it is documented. Ask for the docket any time you want it.
Do you do the council service report as well?
Yes. Aerated systems have to be serviced on a set interval and reported. We do the service and fill in the report at the tank, so you are not chasing paperwork later.
How often does a grease trap need doing?
Most kitchens run somewhere between monthly and quarterly, and your council sets the minimum. We will tell you honestly if you are paying for visits you do not need.
How much does it cost?
It depends on tank size, access and how long it has been. Ring 0405 211 859 with your address and you get a real number, not a range.
