I find this fascinating simply because Edmonton is a major metropolis of about a million people where there is so much to do, and that it seemed to shut down for that game. I’m betting in smaller cities across Canada (and even in parts of Minnesota and around Buffalo) that the spikes would be even more pronounced, especially relative to their normal use.
It’s still more than the top half of the graph – not so misleading as you suggest. And the previous day’s overlayed usage is there to show the relative impact in any event.
Johann: Starting graphs at a non-zero value is perfectly standard procedure; even the great and wise Edward Tufte thinks it’s okay. If what you care about are absolute changes in the value of a quantity instead of relative changes in the value of a quantity, starting at zero is just a waste of space.
And even if you did plot it that way, 320 is a pretty sizable percentage of 400.
Comparing the two graphs, there seems to have been an overall reduction in water use. Spikes aside, wouldn’t beer cause an increase in overall water usage?
Could it be a normal Saturday-Sunday variation, or were a whole bunch of Canadians peeing in the woods that day?
The graph’s showing the instantaneous rate of water consumption on a how-much-would-be-used-over-a-day basis, so a change from 320 ML/day to 450 ML/day is actually pretty big: it implies a 50% change in demand over that interval.
Hmm. Obviously if Canada implemented minute-by-minute variable pricing for water usage people who didn’t need water during those periods would not use it, and the city would be able to shrink its water infrastructure by 15%.
Just another sad example of Canadian socialism ruining the country for everyone.
Anyone also notice how the consumption is slightly higher before the hour preceding the match compared to the previous day? It can only be the pre-match nerves of the public…
As for minute by minute variable pricing, I wonder if that would cost more than the potential 15% infrastructure savings. Sometimes, simpler is better.

Looks like they were also knocking back a few cold ones during the game.

this, of course, is the central plot conceit behind nick park’s film “flushed away”.
(and a dandy film it is, too.)

The numbers begin from 300. It’s not great stuff, it’s misleading and stupid stuff.

In Chicago, in the early fifties, water pressure dropped dangerously during commercials on “I Love Lucy.”

False. There is fuck-all to do in Edmonton.

I wonder whether this can be harnessed like the tides are to generate electricity.

Flushing takes less water than drinking fountains, cooking, etc.
Perhaps this chart would have been better in percentage of previous day.
How about electricity consumption? You’d see it spike at those points as well, as people start kettles or dinner or nuke snacks.

This is apparently like the power usage in the UK.
The largest regular draw of power is just after the annual queens address (christmas message?).
Apparently its attributed to all of them putting the kettle on for a cup of tea.
How very British!
