Trade effluent

The Water Industry Act 1991 defines trade effluent as “any liquid, either with or without particles of matter in suspension in the liquid, which is wholly or partly produced in the course of any trade or industry carried on at a trade premises."

What is trade effluent?

Trade effluent is any liquid waste (effluent) discharged into our sewers from a business or industrial process.

This includes any wastewater derived from a production process or from washing down or cooling activities including wastes from public funded activities such as municipal landfills.

This can be best described as anything other than domestic sewage (toilet, bath or sink waste) or uncontaminated surface water and roof drainage (rainwater).

How do I submit a G02 or G03 form for the customer?

You can submit the application on our retailer portal under the section called G Forms on our portal, where you can also see guidance notes.

How do Retailers view customer’s Trade Effluent sample results?

As per the G4 process, when all sample analysis is completed and verified the results are sent to the trade effluent customer via email and the results are made available to their retailer via our Retailer Portal. Retailers will be sent an email notifying them when results are added. You can find the results undersection 5. Trade Effluent - G Forms – TE monitoring and search by SPID.

What is flow measurement (Private meters)?

Consent conditions may require flow measuring equipment such as a private trade effluent meter to be provided, maintained and records kept. The cost of installing and maintaining such equipment will be the responsibility of the discharger.

Assessment of flow by other means such as private water meters or process meters may also be used by trade effluent dischargers to aid calculation and accuracy of billing, as well as providing improved monitoring of their processes.

Any flow measuring equipment and installation used for trade effluent billing should be to MCERTS standard.

Any private meter used to calculate trade effluent bills should be registered in the market

To notify us that your customer has installed, exchanged or has an issue with a private meter please submit a BO1 form. Please refer to the Market Operational Codes (Schedule 1 Part 3) under B12, B13 and B14 to view the processes that may need to be followed.
