Check with your water retailer before discharging commercial wastewater to sewer. Consent and treatment requirements need to match the premises and activity. Source: South East Water — Trade waste.
What applies
South East Water defines trade waste as non-domestic liquid waste from business activities and provides a consent process. Its food-business policy links interceptor requirements to consent and distinguishes minor trade waste. This is retailer-specific guidance, not a uniform rule for every Melbourne property.

Practical checks for your business
These suggested planning steps help organise site information; they are not an exhaustive legal compliance checklist.
- Identify the retailer and explain process, discharge and equipment before fit-out or changed use.
- Obtain written consent, pre-treatment, servicing, monitoring and discharge requirements for the site.
- Assign maintenance and record responsibilities, including the landlord/tenant split. Check what happens when the operator or process changes.
Confirm the requirement for your site
For a disputed requirement or enforcement issue, ask the relevant authority or qualified adviser to identify the current provision and how it applies. Do not rely on an old penalty amount or general website summary.
Keep a usable decision record
Keep assessments, acceptance conditions, responsible contacts and supporting records together. Note what needs confirmation before changing the service or starting work.

Common question
Is grease-trap servicing the same as consent?
No. Confirm retailer consent separately and arrange servicing to meet the site's applicable conditions.
Discuss your collection requirements
Contact Bundle Waste with the waste type, site and collection requirements. Keep specialist legal, environmental or safety assessment separate from the collection request.
