That goes to the Bearspaw Reservoir so that should be the pipe providing the input water to the treatment plant. In your map, there's blue-red (purples) lines that go out of Bearspaw towards the east that are smaller but still substantial 1350mm-1500mm pipes. These should be the feeder mains for Northwest and North Central Calgary. You can see these zones in this water pressure map (in green and yellow) that can trace a path directly back to Bearspaw.

Yeah, Bearspaw still able to supply 20-25% of the city through other mains. And I think it'll be higher in the future as there's a major new project about to start, called the North Water Servicing Project that'll create a new line going north towards 144 Av then go east to 14 St and could offer a second path for substantial amounts of water to the Northeast in an emergency.
