How User Rates Charges are Calculated

The below comprehensive example will help you understand how the user rates statement is calculated for a single-family residential property. For examples of other types of properties, see our other comprehensive examples (PDF format).
How User Rates Charges Are Calculated
Water Consumption:
To calculate your water consumption charge we take your water consumption in cubic metres (converted into gallons per day) and multiply it by the tiered water rates.
April 15 reading: 2386 cubic metres
August 5 reading: 2502 cubic metres (difference of 112 days)
Total cubic metres: 116(M
2)
consumption x water tier rate(s) x number of days in billing period
(Conversion: 1 cubic metre = 220 gallons)
Water Base Rate:
base rate x number of days in billing period
In this example, the water consumption rate is split among three tiers.
* first 110 gallons are in step 1
* the next 110 gallons are in step 2, and;
* the final 8 gallons are in step 3.
