Keep whey, brine, cleaning liquids and solid cheese waste as separate planning items. Ask your water authority and receiving operator about the actual composition before deciding whether a liquid can enter the sewer.
Information to gather
- Measure liquid volumes and note cleaning chemicals and batch processes.
- Check the trade-waste agreement against the current production method.
- Get written acceptance before offering whey as a byproduct or arranging off-site collection.
What to check before deciding
Do not mix concentrated brine or cleaning chemicals with a proposed food-recovery stream. Compare collection and treatment proposals using site data rather than assuming whey always has a buyer or positive value.
Yarra Valley Water requires an agreement for business wastewater discharged to its sewer; site conditions determine acceptance and charges. See Yarra Valley Water - Trade Waste.
