How we calculate the volumetric charge
We calculate the amount of wastewater charged for each water meter by assigning an industry type with a corresponding wastewater percentage. View industry wastewater percentages
The wastewater percentage represents the proportion of your water use that will be charged for volumetric wastewater services, ranging from 5 per cent to 95 per cent. The exact figure depends on the type of industry you operate in.
A concrete manufacturer, which typically discharges a low amount of wastewater, would be charged at 5 per cent.
A restaurant, which discharges a high volume of wastewater, would be charged at 95 per cent.
