Non-domestic customers: make sure you’re paying the right amount
The wastewater percentage determines how much wastewater you will be charged for under your pricing plan.
It is allocated according to your industry type, unless you request an audit.
There are three types of audits:
Recipe-based – where the water is used as part of a final product, e.g. making beverages.
Water-check meter – where the water is used in operations but is not discharged to the wastewater networks, e.g. irrigation or cooling towers.
A combination of these.
We generally review all wastewater percentages after 2 years.
If there is a change in your wastewater volume before your 2-year review, please contact us to review your wastewater percentage. There is a fee for all reassessments.
If you move premises we will need to re-evaluate the wastewater percentage at your new site.
