Liquid Waste Management for Sydney Businesses
One EPA-licensed partner for every liquid waste stream your site generates — industrial wastewater, chemical liquids, interceptor pump-outs, grease trap servicing and oil collection — fully documented, on your schedule.
Licensed collection, transport and disposal of industrial liquid waste
What Is Liquid Waste Management?
Liquid waste management covers the licensed collection, transport and disposal of any waste in liquid or semi-liquid form — industrial wastewater and trade waste, chemical liquids, oily water from interceptors and separators, washdown water, grease trap waste, used cooking oil and used engine or industrial oil. Because it can't go in a general waste bin, liquid waste has its own regulatory framework under NSW EPA licensing and, for wastewater discharged to sewer, your local trade waste agreement.
Clean Waste manages every liquid waste stream your site generates under one account, one invoice and one point of contact — with a free site assessment to map out exactly what your business produces and the right collection plan for each stream.
Liquid Waste Can't Go Down the Drain or Into General Waste
Trade waste agreements and EPA licensing exist because liquid waste behaves differently once it leaves your site.
Discharging or dumping liquid waste incorrectly is a compliance breach
Tipping wastewater, chemical liquids or oils down a drain, gutter or general waste bin can breach your trade waste agreement or EPA licensing conditions, and cause blockages or contamination well beyond your site. Every liquid stream needs its own licensed collection pathway and disposal certificate.
One Partner for Every Liquid Waste Stream
Most sites generate more than one type of liquid waste — managing them separately means separate contractors, invoices and compliance gaps.

Liquid Waste Management FAQs
Straight answers to the questions Sydney businesses ask most before setting up a service.
What counts as liquid waste?

Can I get one provider for all my liquid waste streams?
Yes. Clean Waste manages grease trap servicing, used cooking oil, used engine and industrial oil, wastewater, chemical liquids and interceptor pump-outs all under a single account and invoice.
Are you licensed to handle hazardous liquid waste?
Yes, Clean Waste holds the required NSW EPA licences for the collection, transport and disposal of hazardous and non-hazardous liquid waste, with full documentation for every job.
What documentation do I receive?
Waste transport certificates and consignment notes are issued for every liquid waste collection, confirming the volume removed and the licensed facility it was taken to.
Is emergency call-out available for spills or overflows?
Yes, priority call-out service is available across Greater Sydney for urgent liquid waste situations, in addition to scheduled collections.
How much does liquid waste management cost?
Pricing depends on the specific stream, volume, contamination level and frequency. Grease trap, used cooking oil and used oil collection each have their own indicative pricing on their service pages, while wastewater, chemical liquids and interceptor pump-outs are quoted individually. Consolidating streams under one account typically reduces your overall cost.
