How User Rates Charges Are Calculated

User rates are calculated differently depending on the type of property that is being serviced.  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).

Charges for a Single Family Dwelling (1 unit)

A household has its water meter read on August 5, which is 112 days since it was last read on April 15. The reading is 2502 cubic metres compared to the previous reading of 2386; therefore, consumption since the previous reading was 116 cubic metres or 25,520 gallons (1 cubic metre = 220 gallons). This works out to an average of 228 gallons per day (25,520/112) for this billing period.

Water fees are calculated by combining the water base charge and daily water usage rate.  To get the water usage rate, take the average gallons (of water) used per day, and split it into the tiered rate structure.  In this example, the first 110 gallons are in step 1, the next 110 gallons are in step 2, and the final 8 gallons are in step 3.  Once you have calculated the daily rates, multiply each by the number of days on the bill and round to the nearest cent to get the totals as they will display on the statement.

CALCULATION OF WATER FEES (DAILY)
Water base charge (daily rate):$1.00613
Water Consumption charges by tiered step (daily rate):
Step 1 – range from 0 to 110 gallons: 110 gallons x $0.00212/gal 0.23320
Step 2 – range from 111 to 220 gallons: 110 gallons x $0.00529/gal0.58190
Step 3 – range from 221 to 330 gallons: 8 gallons x $0.00925/gal0.07400
Total daily rate for 228 gallons – average per day:$1.89523
TOTAL WATER FEES ON STATEMENT (112 days):
Water base charge:$112.69
Water consumption charges by tiered step: 
Step 1 – range from 0 to 110 gallons: 110 gallons x $0.00212/gal 26.12
Step 2 – range from 111 to 220 gallons: 110 gallons x $0.00529/gal65.17
Step 3 – range from 221 to 330 gallons: 8 gallons x $0.00925/gal8.29
Total Water Fees:212.27

Sewer and garbage charges are both calculated as a daily charge.  To calculate either, take the current year’s fee, multiply by the number of days, and multiply again by the number of units.  In this example, there is only 1 unit of each.

SEWER FEE
$0.45057/day per unit: 112 days x 1 unit$50.46
GARBAGE FEE
$0.624658/day per unit: 112 days x 1 unit$69.96

To get the eligible discount amount (5 per cent if paid on or before the due date) take the total of all charges and multiply by 0.05.  Round the answer to the nearest cent and subtract it from the total of all charges.  Continuing with the example, the final charges would look like this:

HOW THESE CHARGES WILL DISPLAY ON THE STATEMENT
WATER BASE RATE – RES$112.69
WATER CONSUMP – RES: STEP 1 – 0 to 110 gallons 0.0021226.12
WATER CONSUMP – RES: STEP 2 – 110 to 220 gallons 0.0052965.17
WATER CONSUMP – RES: STEP 3 – 221 to 330 gallons 0.009258.29
SEWER UNIT RATE – RESIDENTIAL: 1 UNIT50.46

User Rates Estimator

Want to know how much your statement would have been if you used more or less water? Want to see how much adding a suite might add to your statement?  Our new user rates estimator can help you get an approximate idea of how much you may be charged based on the criteria below. 
The rates used in the calculator are from January 1, 2024.  This calculator assumes the property receives water, sewer, and garbage service.

Sorry this calculator only works for residential currently but if you have questions please contact User Rates 250-755-4525 ext. 2 userrates.info@nanaimo.ca.

This is the number of "dwelling units" at the property . For example if you have a house with a suite, you have 2 units. This calculator assumes one water meter. If your property has two meters then select 1 unit and calculate each usage separately.

This calculator currently only works for 1-4 units please contact User Rates 250-755-4525 ext. 2 userrates.info@nanaimo.ca.

The total amount of water in imperial gallons used over the number of days (entered below). To convert cubic meters to imperial gallons, multiply by the amount in cubic meters by 220.

The total days over the period you are calculating. The average user rates statement should be around 120 days.

Your daily usage is {{dailyUsage.toFixed(2)}} gallons. We charge tiered usage per unit.
