These are calculated on your bill by service and for the number of days in the billing period. There are separate standing charges for water and wastewater services. There is no change to the standing charges previously billed by your Local Authority, and the total annual value remains the same.
(A) Actual or (E) Estimate
An (A) or an (E) after a reading indicates whether the reading is an Actual reading taken by the meter reader or an Estimate made by us. Estimates may be used in cases where we do not have an Actual reading.
Meter number
This is a unique number found on the water meter for your premises. If the meter is replaced, the meter number shown on your bill will change.
Meter type: Metric / Gallon
Your meter measures water consumption in either cubic metres (metric) or gallons. If the units consumed are measured in gallons, this volume is converted to cubic metres for your bill. You will see an explanation of the conversion formula on your bill.
Volume
The volume of water supplied or wastewater removed is shown in cubic metres. The symbol for cubic metres is m³. 1m³ = 1 cubic metre = 1,000 litres. If your meter measures in gallons, the volume will have been converted to m³ using the conversion formula explained on your bill.
Metered charges
Metered charges are calculated by taking the volume of water recorded by your meter. The volume is then multiplied by the unit rate(s) for water and/or wastewater, depending on the service(s) provided. There is no change to the unit rates charged.
