Aerated system running as it should?
Southern Liquid Waste services and pumps aerated treatment systems, septic tanks and liquid waste across Shoalhaven, Bowral, Camden, Gerringong and 11 more towns. One phone call, a day that suits you, and a lid that goes back on the way it should.

What we get called out for most.
Everything Southern Liquid Waste 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
Effluent
Effluent pump out services
Effluent pumped out and carted under licence, from single tanks up to a full transfer station run.
03
AWTS
AWTS (Aerated Wastewater Treatment System) maintenance
Routine maintenance on a set interval, so nothing on the property gets to the emergency stage.
04
Ablution
Ablution block & portaloo servicing
Scheduled servicing that keeps the system inside what the manufacturer and the council both expect.
05
Grease
Grease trap cleaning
Kitchen grease traps emptied and washed out on a schedule that keeps the council and your kitchen happy.
06
Oily
Oily water pump out
Oily water and separator pits pumped and disposed of under licence, with the tracking paperwork.
Straightforward, start to finish.
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.
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.
Your service report, done at the tank
Aerated systems need a service record for the council. It gets filled in while we are there, not from memory afterwards.
We leave it safe
An unseated septic lid is the most dangerous thing on a rural block. Ours go back properly, every time.
