That's still fixable. Just like how most computers are air cooled and not water cooled. They could build a very large air cooling tower and not need water at all.
Cooling from cheap to expensive:
1. Take in water, return water some amount hotter. Requires the most water to limit temperature rise.
2. Take in water, evaporate some of the water in a cooling tower. Results in less water, but also takes less water and controls temperature rise better
3. Dry cooling.
Most systems are actually something of a hybrid of the three.
