Water in Metro Vancouver might seem like a limitless resource, but it's time for that notion to go down the drain. When it comes to home water use — for drinking, bathing, toilet flushing and more — Metro Vancouver is a pretty thirsty place. Residential water use in Metro Vancouver is 270 litres per capita per day. That's less than the City of Montreal's 286 litres per capita per day, but more than Toronto's 219 per day or the 210 per day used by residents of Calgary. So how do the thirsty residents of Metro Vancouver use all that wet stuff?
