It has nothing to do with tap water, they provided false information. It is pulling cold water from the lake, running it through heat exchangers throughout the system, then the cold liquid at each system is used to cool the buildings, etc. The slightly warmer water goes back into the lake, not into the drinking water system. |

Edit: looks like a bit of both? See pg. 6:

Though the city drinking water is pulled from deeper out so probably that supply is cooler to begin with:
