I guess they're would be diesel generators for that in reality. We need an engineer to calculate the flow needed because given how far away the far end is from the water that could end up behind one huge generator, not to mention the size of the pipes.
It's worth mentioning that they don't seem to be burying any massive water pipes so this isn't likely to be done in reality.
the same way that water towers work - when the pumps are running (power is on), you pump water into the tower; then, when the pumps fail, gravity continues to provide water pressure as water drains from the tower. The water tower effectively acts as a "battery" in the system, storing energy (and water) and then releasing it as needed
I didn't design the project, but I would imagine that moving water would be cooler than stagnant water. Other pre-industrial revolution pump designs like a hydram pump could keep cool water moving from the sea as well
See e.g. [1], so they could either funnel air into the ocean and back up for direct temperature exchange, or alternatively use the breeze generated top-to-bottom in the building to drive "active" pumps.
Or just have Olympic-sized swimming pools in the basement that you've actively pumped water into. If the pumps are out they'll have a lot of thermal inertia.
