Trade Waste

Trade Waste

Trade waste is the liquid waste from any industry, business, trade or manufacturing premises, other than domestic sewage from a hand basin, shower, bath, toilet or other domestic fixture. If you're disposing waste to the wastewater system, you need to ensure you have a trade waste permit because uncontrolled or illegal discharge of trade waste causes serious problems in the sewerage system including flooding and overloading, blockages, corrosion, hazardous work environments, even failure of sewage treatment processes. The City is responsible for preventing these contaminants from entering the sewerage system, ensuring that the health and safety of the community and the environment are protected.
Applying for a Trade Waste Permit
To apply for a Trade Waste permit please fill in the attached Trade Waste Application Form in the Quick Links section, and return it to the City either through email or through post to PO Box 2042, Boulder, WA 6432.

The grease and fat contained in wastewater can accumulate both in your drains and the City's sewer system, resulting in blockages and overflows. The potential cost to your business associated with a drain or wastewater blockage can be significant, not only in finding and clearing the blockage but also the effect it has on the normal operation of your business. You should be aware that if a wastewater blockage is attributable to your business you may be required to pay the substantial cost for removing the blockage and the associated cleanup.
