There was a June 8, 2024 briefing where they had the manager of Drinking Water Distribution to describe the system at a high level. As powderjunkie reasoned, Bearspaw by default can/already moves water northwards on separate mains. At that time it was still producing 130 megalitres; it could do even more but the NW/North couldn't actually use or store any more water or move it to other areas.
The water pressure zone map show in his presentation can be found here:

The North Calgary Water Servicing project should come in handy, allowing for more water to reach the NE from a separate path. The NE is probably the region most affected since it's so far from both Bearspaw and Glenmore.
