Calgary water rates have surged since 2009: Here's the interactive graph you need to see

In 2009, the average Calgary family's monthly utility bill for water, wastewater and stormwater (drainage) was $64.77.

This year, nine years later, that same family is paying on average of $115.93, an increase of more than 78 per cent.

The cost of providing wastewater services increased the most, jumping from an average of $22.14 in 2009 to $53.91 in 2018. That's an increase of more than 143 per cent.

The city says there are many factors in the increased costs. Inflation, wastewater plant capacity increases, upgrades to some drainage services in older communities, river flooding protection projects and others.

And the increases are not done yet. Calgary city council approved earlier this month indicative rate hikes for water, wastewater and stormwater services.

The plan is to essentially freeze water ratesbut increase wastewater rates by up to 5.5 per cent per year and stormwater rates by up to fiveper cent over the course of the four-year budget.

If the higher rates are imposed, it would add $17 dollars a month to the typical homeowner's water bill or about $200 per year.

For example, rolled together, the potential hikes could turn an average $116 monthly water bill today into a $133 a month bill in 2022. That means the average bill could jump by $204 a year by2022.
