Trade waste

We can help your small business or agribusiness to manage trade waste and provide advice on pre-treatment options.

Trade waste is industrial and commercial wastewater that is sent through the sewers for treatment.

Only trade waste that complies with specific guidelines can be discharged into the sewerage system.

The Customer Charter – Trade Waste sets out the rights and obligations of both Lower Murray Water and our customers in relation to trade waste services.

Apply to discharge trade waste

To apply to discharge minor or major trade waste, complete a Trade Waste Application.

You will need to include information about:

  • plumbing fixtures
  • industrial chemicals
  • pre-treatment facilities.

You must also meet our trade waste acceptance criteria.

There is no application fee.

Submit your application:

To pay the fee by credit card, contact us. We can’t process your application until the fee has been paid.

Depending on the nature of your trade waste, we may need more detailed information. In this case, we will contact you.

Trade waste categories

There are 2 main categories of trade waste. The type and volume of wastewater we need to treat determines your costs and responsibilities. For trade waste charges, see Urban charges.

Minor trade waste

Minor trade waste is from businesses that discharge relatively small volumes of wastewater into the sewer – for example, hotels, restaurants, take away food businesses, laundries and car washes.

Minor trade waste customers need a Consent to Discharge Trade Waste. They are charged an annual fee that is incorporated into their quarterly bill.

Major trade waste

Major trade waste is from businesses that discharge large volumes of wastewater into the sewer, generally more than 1,000 kilolitres (kL) per year – for example, fruit and vegetable processing, fruit packing, abattoir, and winery operations.

Major trade waste customers are required to sign a Trade Waste Agreement with us. They are charged on a quarterly basis based on the organic load, calculated using the COD (chemical oxygen demand), suspended solids, sodium and hydraulic loadings in their wastewater.

An establishment fee per megalitre (ML) also applies.


Minor and major trade waste businesses must have appropriate pre-treatment facilities to treat wastewater to meet our guidelines. For example, a grease interceptor, petrol and oil interceptor, silt trap or acid neutralising tank.
