What is trade waste?

Trade waste is all non-human liquid waste generated on commercial properties that’s discharged to our sewerage system. It includes liquid waste such as grease, oils and chemicals.

Pre-treatment and trade waste permit

If you own a business that generates trade waste you will need some form of pre-treatment and a trade waste permit. Follow the steps below. 

Trade Waste Search 

If you are going to purchase a new business that generates trade waste we recommend you conduct a Trade Waste Search. This search will detail the pre-treatment facilities currently on site and ensure the trade waste fees are adjusted at settlement (if applicable). You will also need a trade waste permit. 

Follow these steps for your business:

2. Apply for your Trade Waste Permit 

If your business does one or more of the following, you need a Trade Waste Permit:

  • Businesses that wash or clean any utensil or equipment and then discharges the wastewater into Unitywater infrastructure. These businesses are required to install grease traps as part of their Trade Waste Agreement with Unitywater
  • Businesses that produce non-domestic liquid waste containing chemicals or residue from a commercial or industrial process. These businesses are required to install pre-treatment devices as part of their Trade Waste Agreement with Unitywater
  • Businesses that have an existing pre-treatment device on the property must apply for a new Trade Waste Permit. 

To apply for a Trade Waste Permit, please complete the following form and return it to Unitywater.

Prior to submitting a plumbing application (to council) that incorporates trade waste, you are required to submit your permit application to our Trade Waste team along with:

  1. A hydraulic plan detailing fixtures, and the pre-treatment device/s and manufacture details.
  2. Plan assessment application (PDF 83KB). Plan assessments are undertaken to ensure what is proposed on the hydraulic plans will not have any harmful effects on the sewer network. The hydraulic plans show the proposed fixture rating and pre-treatment devices to be installed. The applicant will be notified in writing whether the proposal is satisfactory and a Letter of Approval will be supplied which will be required by the relevant Council as part of the plumbing assessment. This application requires payment of plan assessment fee.

Unitywater has three types of Trade Waste Discharge Permits (high risk, medium risk and low risk). They are categorised by the level of risk associated with the waste. Upon application, we will assess your level of risk and will assign the relevant Trade Waste Discharge Permit classification. Please refer to the risk assessment on page 15 of the Trade Waste Management Plan (PDF 596KB).
