Liquid Waste Removal

Oily Water & Hydrocarbon Removal

EPA J120 licensed removal of oily water and hydrocarbon waste — and the sludge layer beneath it. Triple interceptors, oil-water separators, wash-bay pits, and workshop sumps cleaned out across Sydney, with photo evidence, tipping dockets, and EPA transport certificates.

Our Specialty

The Sludge Beneath the Oily Water

Pumping off the liquid is the easy half. Our lane is the settled layer — the compacted sludge in interceptors, separators, and wash-bay pits that stops them doing their job.

Triple Interceptors & Oil-Water Separators

Separators fail because of the settled sludge layer, not the water. We scrape and wash the plates, baffles, and floor, then vacuum the lot out — cleaned to the base under our J120 licence.

Wash-Bay Pits & Workshop Sumps

Grit, degreaser residue, and oily sludge build up until pits stop draining. We pump them down, clean them out, and leave them working.

Spills & Emergency Pump-Outs

Hydrocarbon spills, flooded bunds, and contaminated water — contained, extracted, and transported under EPA J120. Our enquiries line is open 24/7.

How It Works

Our Oily Water & Interceptor Process

Licensed, documented, and cleaned to the base — from collection to disposal.

01

Assessment

Identify the waste type, volume, and contamination level. Confirm EPA classification and disposal pathway.

02

Set-Up

Exclusion zones established, with spill containment and absorbents deployed where the job calls for it.

03

Pump-Out & Sludge Removal

Oily water drawn off and the settled sludge layer vacuumed out — interceptors, separators, and pits cleaned to the base.

04

High-Pressure Wash

Plates, baffles, and walls jet-washed so the asset separates properly again — not just emptied.

05

Licensed Transport & Disposal

Sealed vacuum unit to an EPA J120 licensed facility. Tipping docket and EPA transport certificate provided.

06

Photo Evidence

Before-and-after photos of the asset for your records, plus an honest read on its condition.

Common Questions

Oily Water & Interceptor FAQs

Do you take the sludge or just pump the water off?

Both — the sludge is the point. Interceptors and separators fail because of the settled layer, so we scrape and wash the plates, baffles, and floor, then vacuum everything out under our J120 licence.

What paperwork do we get?

Photo evidence of the asset before and after, a tipping docket for the load, and an EPA transport certificate.

Our separator hasn't been serviced in years — can it be brought back?

Usually, yes. Long-neglected separators carry compacted sludge a quick pump-out won't shift. We deep clean them and tell you straight if anything is damaged before we start.

Do you respond to spills?

Yes. Oily water and hydrocarbon spills are part of our J120 scope — containment, extraction, and licensed disposal. The enquiries line is open 24/7.
