One truck. One name on the door.
Mac Waste Group is owner-operated, pumping septic tanks, treatment systems and liquid waste since 2001 across Maffra, Sale, Traralgon, Bairnsdale and 25 more towns. One call, a straight answer, and a job that does not need doing again next month.

What the truck is set up to do.
Everything Mac Waste Group handles, in the order people ring about it.
01
Septic
Septic tank cleaning
The standard household pump-out. We lift the lid, vacuum the tank down, check the outlet and leave the lid seated properly.
02
Septic
Septic treatment plant cleaning
Aerated treatment systems serviced, pumped and left running the way the manufacturer intended.
03
Septic
Septic tank installation
New systems supplied and installed, sized to the block and the number of people actually living on it.
04
Water
Water tank cleaning
Rainwater tanks drained, cleaned out and refilled, so what comes out of the tap is what you thought was in there.
05
Grease
Grease trap cleaning
Kitchen grease traps emptied and washed out on a schedule that keeps the council and your kitchen happy.
06
Triple
Triple interceptor cleaning
Triple interceptors pumped and washed down, so the last chamber is doing its job and not passing solids on.
07
Car
Car wash pit cleaning
Car wash pit cleaning — quoted before we start, and finished the same day where we can.
How the day goes.
A phone call, and it is booked
One conversation. You hear what it costs, you hear when we can be there, and that is the booking done.
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.
