To apply for a Trade Waste Permit, please complete the form on the left 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:
- A hydraulic plan detailing fixtures, and the pre-treatment device/s and manufacture details.
- 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).
