Industrial chillers on the hotels produce quite a bit of run off. Where does it go?

Cooling towers re-use the same water, losing some to evaporation, and what is released goes through the sewer system.

The chillers don’t really have runoff. The cooling towers associated with the HVAC water chillers, do. That blowdown water typically goes to the municipal sewage system.
