Trade waste

Trade waste is any commercial or industrial liquid waste that flows into our wastewater (sewer) system.  It does not include stormwater or wastewater that goes into the sewer from domestic toilets, kitchens, bathrooms or laundries.

Any business that produces liquid waste larger than domestic quantities may need a trade waste consent.

What type of business may need a consent?

The types of businesses that may need a trade waste consent are: 

  • food processors - meat, fish, vegetables, fruit
  • hospitals, dentists
  • metal finishers
  • service stations
  • restaurants, cafe, take-a-ways
  • freezing works

For a list of the types of businesses producing trade waste -  see Schedule 1D of the Trade Waste Bylaw

Why you may require a trade waste consent

Industries must assist us to comply with the conditions of our Coastal Discharge Permit (the council's authority to discharge both domestic and industrial wastewater into the ocean environment). This means wastewater must undergo pre-treatment to reduce the level of solids, oils and greases to comply with the permit. 

Read our Trade Waste Bylaw

Trade waste consent application

All premises discharging trade waste to the council's sewer system will require a trade waste consent. If you discharge trade waste without holding a consent or exceed your consent conditions you are breaching our Trade Waste Bylaw. If convicted, fines can reach up to $200,000.

Grease trap tips

Do scrape all solids off plates before washing them.

Do service your grease trap on a regular basis.

Do ensure your grease trap is working efficiently and correctly.

Don't use large amounts of detergent when washing.

Don't tip oil and fats into your sink - these can solidify in the sewer lines causing blockages and overflows.
