Hard block? That is the whole job.
Mammoth Liquid Waste pumps out tanks the big rigs cannot reach since 2022 across Rockhampton, Yeppoon, Emu Park, Gladstone and 27 more towns. You get a person on the phone, a price before we start, and the ground left as we found it.

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.
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.
