Liquid trade waste

Liquid Trade Waste is all liquid wastes other than domestic sewage that are discharged to the sewerage system. Septic tank and pan wastes are examples of liquid trade wastes that place much greater demands on sewerage systems than domestic waste.

If they are uncontrolled, liquid trade wastes can pose serious problems to public health, worker safety, Council's sewerage system and our environment.

Impacts of poor liquid trade waste include:

  • grease, oil, solid material: if these are not removed onsite, they can cause sewer chokes and blockages and untreated sewage discharge
  • sewage odour problems and corrosion of sewer mains, pumping stations and sewage treatment plants.

Business and industry requirements

Council is able to accept liquid trade waste into its sewerage system from businesses and industry that apply for and receive approval under section 68 of the Local Government Act 1993. Discharging liquid trade waste without approval is an offense under section 626 of the Act.

Fees applied to Liquid Trade Waste customers are published in Council's current Operational Plan.

Preventing backflow

Backflow is the unwanted flow of water back into the system and has the potential to introduce pollutants and contaminate the water supply. It can happen if there is a sudden loss of pressure in the water supply system which creates a vacuum effect that sucks water from your property into the water supply. 

To prevent back flow, all properties connected to the Eurobodalla water supply must install a back flow prevention device.

We have a backflow prevention program that is helping to reduce the risk of a backflow event compromising our reticulated water supply system.

High risk properties

Some properties pose a high risk to our water supply according to AS/NZS 3500.1 Plumbing and Drainage Water Services hazard ratings. These properties need more protection installed at the water meter. If your property is at risk, Council will issue you with a notice that will ask you to install a registered or testable backflow prevention device and advise you of our annual testing requirements.
