Small changes make a big difference

The average person living in Ottawa uses about 183 L of water a day. That's over 700 L every day for a family of four. At our current water rates, that costs about $935 a year.

Where do we get our water?

In Ottawa, most of our drinking water comes from the Ottawa River. After we use it – for brushing our teeth, washing our carrots, or taking a hot bath – the wastewater flows down the drain, through the sewers to the wastewater treatment plant, where it is treated then sent back to the river.

Canadians are water guzzlers*

Ottawa residents use an average of 183 L per person per day in their homes. In the summer, when lawn and garden care is added, consumption can increase by 30 L per day, which amounts to an additional 3600 L of water per person per summer (enough to fill 2.5 hot tubs).

Canadians' daily water use

Are you flushing money down the toilet? In Canada, up to 25% of toilets leak. That’s 1.8 billion litres of clean, treated water going down the toilet every day. That’s the same amount of water that flows over Niagara Falls every 11 minutes.
