Wastewater generated by industry, small business and commercial enterprise is referred to as trade waste.
Trade waste can be very different to regular household wastewater because it may contain fats, oils and greases and/or toxic or harmful substances such as acids, petroleum products, heavy metals, solids, organic solvents or chlorinated organics.
What impact can trade waste have on the environment?
Uncontrolled or illegal discharge of trade waste may cause serious problems in the wastewater system such as overflows and overloading, blockages, corrosion, hazardous work environments and failure of the sewage purification process.
Trade waste can impose an additional load on the wastewater system, and therefore requires extra, and more costly, treatment to keep our communities, the environment and our network safe.
There are additional costs to manage and treat trade waste safely and effectively. These costs go towards the extra chemicals, cleaning and electricity required to treat trade waste so that it does not pollute our environment, harm our people or cause blockages, overflows or damage to our network.
Sensitive, careful and effective wastewater treatment, which removes trade waste contaminants, is a critical safeguard for public health and the environment.
