Cooling Towers and Credits: Why They Matter for Industries

Now, let's talk about what cooling tower credits actually are. They are often misunderstood. Utility companies charge sewer rates based on a simple assumption: they bill for about 90% of the water entering your building, expecting it to return as sewage. However, cooling towers evaporate most of the water they use, which disappears into the air and never enters a sewer drain. Despite this, you are still being charged for it as if it did. Cooling tower credits are a correction to this billing error. They are financial credits on your sewer bill for the water that evaporated, preventing you from paying for sewage that was never created.
