Pre-treatment products

Get the facts on why you need to pre-treat waste, what products to use, approvals and more.

Why is pre-treatment required?

Pre-treatment of trade waste ensures wastewater discharged from your premises meets our requirements and prevents contaminants that can harm public health and the environment from entering our wastewater system.

Your trade waste permit will indicate whether you need to pre-treat your waste.

The following fixtures and products are acceptable for pre-treating your waste:

Food waste disposal

Food waste disposal units are under-sink devices that grind food waste into small particles.

Under by-laws, you're prohibited to install or run food waste disposal units. Food waste is better disposed of via the solid waste disposal system.

Unapproved fixtures or products

If you install unapproved fixtures or products that don't meet our standards, you'll be required to replace these at your own expense.

If you're proposing to install an unapproved fixture or product, we'll firstly need to review this along with your trade waste permit application. You may also need to clearly demonstrate that the device is suitable for its intended use.

If you plan to cancel you trade waste permit and/or shut down your pre-treatment device, you need to let us know before doing so. If you're not the property owner, you'll need to provide written permission from the owner to disconnect the fixture. 

A licensed plumber will have to come to remove the fixture, bridge the fixture or re-route your wastewater lines to by-pass the fixture.

If a fixture, such as a grease arrestor or dilution pit, is shut down but left in place, it must first be cleaned and pumped out by a licensed liquid waste contractor.
