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 Trade Waste Fee
The annual trade waste fee covers the cost of Council carrying out an annual inspection of your business premises to ensure that you are complying with conditions of your approval. Your business will be charged one of the following fees, set in accordance with Council’s 2019/2020 Revenue Policy, depending on the nature of your business activity:
- Category 1 Discharger - $103.00 – this fee applies to dischargers requiring minimal pre-treatment with low impact on the sewerage system. For example – Florists, beauticians.
- Category 2 Discharger - $206.00 – this fee applies to dischargers with prescribed pre-treatment. This is the most common category for businesses in Cowra. For example – restaurants & food premises, mechanical workshops, motels & hotels and car washes.
- Category 3 Discharger - $690.00 – this fee applies to larger dischargers requiring more complex pre-treatment. For example – large industrial businesses.
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 the NSW DPI Water) that a certain percentage of your daily average water consumption is liquid trade waste. The remaining percentage is deemed to be used for domestic purposes (i.e. toilets, hand basins, kitchens, showers etc).
Council’s 2019/2020 Revenue Policy sets a usage charge of $1.74/KL for businesses that have installed the required pre-treatment devices, and $15.96/KL for businesses that have not installed the required pre-treatment devices.
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 trade waste service.
Also, if your business is found to be discharging liquid trade waste without approval, or in non-compliance with the conditions of an approval, Council will charge a non-complying fee. Council’s 2019/2020 revenue policy current sets this fee at $15.96/KL of liquid trade waste.
In accordance with section 103 of the Local Government Act 1993, renewal of an approval is required every five years.
