Apply for multiple occupancy discharge approval

Step 1.Understand your pre-treatment requirements

Before you make an application, make sure you understand the pre-treatment requirements relevant to the business activities onsite. In most situations, waste streams generated by different activities must not be combined prior to pre-treatment.

As a guide, multiple occupancy developments such as shopping centres require individual pre-treatment equipment. Businesses could include, but not limited to:

• Food providers (e.g. grease arrestors, can be shared between food businesses)
• Laundromats (e.g. lint screens, cooling pits)
• Mechanical workshops (e.g. oily water separators)
• Supermarkets (e.g. grease arrestors, extractors)

Depending on the individual activities, a variety of equipment may be required.

Step 2.Have your documentation ready to upload

To complete this application you will need to attach:

• Relevant hydraulic plans and pre-treatment equipment specifications (as appropriate)
• A copy of the land owners consent (if property is leased)
