Stormwater, grease, septic, and J120 oily water — for commercial and industrial clients across Sydney. We target the complex jobs: heavy sludge, neglected tanks, and long runs from truck to asset. EPA licensed, documented on every load.
Every liquid waste job ends with lawful, EPA-licensed transport and disposal — that's the baseline. The work we specialise in is what happens before that: tanks and pits carrying years of settled sludge, assets a long way from truck access, and infrastructure that needs to be cleaned back to condition — not just emptied.
We work across four streams — stormwater assets, grease traps, sewage and septic systems, and J120 oily water — for commercial and industrial clients. Pump-outs are always on the table; sludge cleanouts are where we earn our keep.
We service commercial and industrial clients across New South Wales — 24/7 line for critical incidents.
Most people picture a liquid waste job the same way: a truck arrives, sucks out the liquid, and leaves. That's not what turns up from ASB. Our hydro vacs carry two systems a standard liquid waste truck doesn't — and they're the reason we take on the jobs we do.
Purpose-built vacuum systems with the pull to lift heavy sludge, silt, and settled solids — not just free liquid — from deep pits, tanks, and wells. Years of compacted buildup comes out, at depth and over distance.
If it's settled, hardened, or compacted, it takes real vacuum power to shift — that's what these trucks are built around.
The cleaning system a standard liquid waste truck doesn't carry. High-pressure water breaks up hardened buildup, scours walls and benching, and washes pits and tanks back to bare concrete — so the asset works the way it was designed to.
When the asset is nowhere near truck access — basement plant rooms, rear-of-building tanks, pits deep inside a site — we run hose from the street and keep full suction at the far end. Runs beyond 100 metres are part of the job.
A standard liquid waste truck pumps out liquid. A hydro vac breaks up what's settled, lifts it over distance, and washes the asset clean. It's the difference between an asset that's been emptied and one that's been restored.
From heavy sludge cleanouts to emergency response — the full spectrum of liquid waste removal, with scheduled programs available once assets are back to baseline.

Liquid waste disposal is tightly regulated by the NSW Environment Protection Authority. Illegal dumping carries significant fines and reputational damage for the waste generator — not just the transporter.
When you use ASB Vac Services, you have complete confidence that every load of liquid waste we collect is transported under a valid EPA licence and disposed of at an approved licensed facility. We provide the paperwork to prove it.

They reduced the amount to pay because it didn’t take as long as they expected. And they even cleaned up afterwards. Highly recommended"
"I recently engaged ASB Vac Services to clean out the onsite detention tank at the rear of our building & pits located in our basement using their sucker truck, & I couldn’t be more impressed with the service. From the very beginning, Alen was extremely professional & clearly knowledgeable, bringing over 15 years of experience in the industry. He took the time to explain the process, answered all my questions, & even followed up with courtesy calls afterward to ensure everything met my expectations. The quality of his work was outstanding, & the entire job was completed efficiently & thoroughly. I highly recommend ASB Vac Services for anyone needing this type of work. I’ll definitely be continuing with a preventative maintenance plan after seeing the level of care & expertise Alen & the team provided. Exceptional service from start to finish!"
"The Lads at ASB go above and beyond every time!!! SSTC Group highly recommend them."
