What is a water credit specialist?

A water credit specialist helps businesses recover evaporation credits (also called sewer credits) for water that evaporates from cooling towers, irrigation systems, and condensers. Since this water never reaches the sewer system, businesses shouldn't pay sewer fees for it. Water credit specialists like RPM document evaporation usage and work with utilities to secure refunds and ongoing credits.

How do evaporation credits work?

Evaporation credits work by documenting the water that evaporates from your cooling towers or irrigation systems rather than entering the sewer. Utilities typically charge sewer fees based on water consumption, assuming all water exits as wastewater. By installing sub-meters and proving evaporation volumes, you can receive credits reducing your sewer bill by 20-40%.

How much can I save with evaporation credits?

Most businesses save 20-40% on their monthly sewer charges. RPM clients collectively save over $5 million annually. One national retailer saves over $1 million per year from less than 100 sites. ROI is typically achieved within 10-24 months, with savings continuing year after year.

What Are Evaporation Credits?

Here's something most facility managers don't realize: Your utility company charges sewer fees based on how much water comes into your building—assuming all of it goes out through the sewer.

But cooling towers, irrigation systems, and condensers evaporate a huge portion of that water. It goes into the air—not down the drain. Yet you're still paying to "dispose" of it.

Evaporation credits (also called sewer credits) are refunds for these fees. We measure what evaporates, prove it to your utility, and get you credited—typically 20-40% off your sewer bill, month after month.
