@nprofile1q... That depends on the cooling load of the data center, but you are essentially correct. By hooking up to the municipal water supply, they are using potable water for non-potable service.

By comparison, the chemical plant where I work has its own water wells and treatment facility. Some of the water is potable, and the rest is so called "process" water. That process water is used in our cooling towers. @nprofile1q...
