The reports make it sound like the water isn't recycled and that the water is "used" by the data center, as if they're talking about continuous use. Whether that's accurate or not, I don't know. You'd think you could cool the water passively and recirculate it, but then you're adding more radiant heat into the environment.

If water is running through a closed system you wouldn't think there'd be an issue with treating it and releasing it back into the water supply, but I'm sure it's not worth the decrease in net shareholder value.
