Trade waste pre-treatment requirements
Pre-treatment facilities may include grease arrestors, oil separators, cooling pits, lint traps and dilution pits. We recognise grease arrestors sized 1,000 litres minimum and 5,000 litres maximum.
Your role in the trade waste process
You may be consulted to give advice or engaged to carry out plumbing and drainage works by property owners or developers of new developments or redevelopment projects.
Advice to reduce wastewater discharge
Simple but effective changes to onsite operations and procedures may improve wastewater quality and reduce operational costs. These include:
- Don't pour oil, grease or fats down the sink - recycle all spent cooking oils. Most used cooking oils are suitable for recycling. Contact local recycling companies for further details.
- Discard all solids food waste (food scraps, batter mix, etc.) to the garbage for recycling or landfill.
- Don't overuse detergent and ensure it is biodegradable.
- After the pre-treatment facility has been cleaned out by an accredited contractor, refill the facility with clean water to promote immediate compliant operation.
