Commercial water and wastewater charges

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. 

For example:

  • 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.

(Unless otherwise agreed using our wastewater audit process.)
