If you have an existing business, or you are proposing a new business activity, and that activity generates liquid waste that is discharged to the sewerage system, then it is a legal requirement that you lodge a Liquid Trade Waste Application with Council. If liquid trade waste is produced but not discharged to the sewerage system Council still need to be notified.
If your business activity only discharges to the sewer from toilets, hand wash basins and showers then you do not need to lodge a Liquid Trade Waste Application.
Council regulates liquid trade waste dischargers so waste does not:
- Cause problems for the sewage treatment process.
- Compromise the health and safety of council workers
- Damage Council’s infrastructure and assets.
- Significantly increase maintenance costs.
- Overflow the sewerage system.
- Cause significant odour complaints.
- Harm the environment.
- Harm public health and safety.
- Degrade effluent and biosolid quality and management.

As a condition of Council’s Liquid Trade Waste Approval for your business, your business will need to have installed all required pre-treatment devices.
The type of pre-treatment devices that are required for your business will depend on the nature of the business activity, the contaminants in the liquid trade waste, and the volume and strength of the liquid trade waste.

Annual Usage Charge
The annual usage charge is calculated based on the total volume of liquid trade waste that your business discharges to the sewerage system. This charge covers the cost of treating the liquid trade waste at Council’s sewage treatment plant.
To calculate the total volume of liquid trade waste, it will be assumed (based on guidelines developed by DPI Water) that a certain percentage of your daily average water consumption is liquid trade waste. This is calculated from your water meter reading.
Council’s 2021/2022 Revenue Policy sets a usage charge of $1.79/kL for businesses that have installed the required pre-treatment devices, and $16.40/kL for businesses that have not installed the required pre-treatment devices or is discharging in non-compliance with conditions of approval. (One kL equals 1000 litres)
If your business is discharging a liquid trade waste to the sewerage system without an approval, or in non-compliance with the conditions of an approval, your business is committing an offence and Council has legal powers to issue a fine, penalty notice, clean-up notice or prevention notice. Council also has the legal power to revoke your approval or disconnect your sewerage service.
