Controlled Waste Tracking Forms (CWTF)

The City reserves the right to reject loads if the tracking form is not completed accurately or if any information is missing. To prevent this, please ensure that these forms are filled out correctly and emailed through prior to disposal.

In cases where waste originates from a mine site and no specific address is provided, it is essential to include the tenement number and shire locality, along with the company and mine site name.

  • Please note that the responsibility for identifying the type of waste rests with the Controlled Waste Carrier. Additionally, when quoting unseen works, it is highly advisable to include a disclaimer to the waste generator, in case the waste does not match the description provided and is subsequently rejected.

What happens if my load is rejected?

In order to safeguard both the treatment plant and the quality of the discharged effluent, operators will not accept any loads that do not pass the initial assessment or any loads that are suspected of not meeting the acceptance criteria.

The carrier will be informed in writing, and a non-conforming load form will be completed and submitted to the DWER Controlled Waste Team.
