What we pump

What the truck is set up to do.

Everything Mammoth Liquid Waste handles, in the order people ring about it.

01

Septic

Septic waste tank pumping and desludging

The standard household pump-out. We lift the lid, vacuum the tank down, check the outlet and leave the lid seated properly.

02

Grease

Grease trap cleaning and pumping

Kitchen grease traps emptied and washed out on a schedule that keeps the council and your kitchen happy.

03

Greywater

Greywater removal

Grey water pits and tanks emptied, and the outlet checked while the lid is off.

04

Oily

Oily water and sludge removal

Oily water and separator pits pumped and disposed of under licence, with the tracking paperwork.

05

Wash

Wash bay and car wash pit desludging

Wash bay pits and silt traps emptied before they overflow into the yard drain.

06

Pond

Pond desludging and draining

Blocked drains cleared and the line checked, so the same blockage doesn't come back next month.

07

Ablution

Ablution block and holding tank waste removal

Holding tanks pumped on a standing run, so it never becomes an emergency call.

What happens on the day

No mystery, no mess.

You ring, we give you a day

No answering service, no ticket. You get a person, a price and a day that suits the truck and suits you.

Nobody knows where the lid is. That is fine

Half the jobs start with a probe and a shovel. If the lid has been buried since the eighties, we will still find it.

The tank goes out, not the lawn

Hose run from the truck, tank vacuumed down, sludge and crust taken with it. Boards down if the ground is soft.

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.

Documented every visit

Trade waste is only compliant if it is recorded. Every visit is documented and the record is yours.

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.
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 0400 278 008 with your address and you get a real number, not a range.
Book it in

Book it while it is still a job, not an emergency.

Ring 0400 278 008 and speak to someone, or leave your details and get a call back.

We read every one of these. If it is urgent, ring instead — it is faster.
