All 20 mm and 25 mm meters have a backflow prevention device. This is suitable for properties that have a low backflow hazard.
You must have a backflow prevention device on your water connection to reduce the hazard your activities may pose to our water supplies. You'll need to engage an accredited backflow plumber to assess your site and install the right kind of backflow device.
You'll be charged a wastewater service charge and wastewater usage charges based on our measure or estimate of the volume of wastewater discharged from your site. We calculate these charges using a wastewater usage discharge factor (WUDF). We've identified standard (typical) WUDFs for a range of industries, and we'll use a standard WUDF unless your property has a discharge meter.
If you believe the standard WUDF doesn't apply to your property and you don't have a discharge meter, you can ask us to review it. Complete a WUDF variation request form (49 KB, XLSX). You'll need to provide evidence to support your request in line with the requirements detailed in Appendix 1 of our . You can request a review once a year for free.
We'll have an agreement with you if you have special equipment or conditions. It's important that you understand it. If you need help to understand your agreement, call:
If you sell your property, you must tell potential buyers about any agreements that apply.
