We calculate charges based on water you use. We choose the lowest of the current and previous two consumptions. This way you don’t pay extra sewer charges on seasonal watering.
Let’s look at the billing for a typical two-person household. Like many, they use more water in the summer months for their lawn and gardens. Let’s suppose that these are their last three readings:
- 50M3 Time period: Mar 20 – Jul 20 (123 days)
- 80M3 Time period: Jul 21 – Nov 19 (122 days)
- 35M3 Time period: Nov 20 – Mar 19 (120 days)
Because 35M3 is the lowest, that’s what we’ll use to calculate the sewer charges.
First, we find out the average daily usage for the 30m3 consumption period:
- 35M3 divided by 120 days = 0.29M3 daily.
Next, we calculate the Saanich sewage charge:
- Average daily use X the days in the billing period X the Saanich sewer rate = Saanich sewage charge.
- 0.29M3 x 120 x $1.409 = $49.03
Finally, we calculate the Capital Regional District (CRD) sewage charge:
- Average daily use X the days in the billing period X the CRD sewer rate = CRD sewage charge
- 0.29M3 x 120 x $2.051 = $71.37
Your bill shows the consumption that we used to calculate sewer charges. This figure can be higher or lower than the actual consumption of your lowest consumption period; our software is recalculating the amount based on the number of days in the billing cycle.
