ICA Evaporation & Carryout Calculator

This calculator is designed to help you show the amount of water purchased from the potable water system that is not discharged to the sanitary sewer system for treatment.

Simply enter your data and you have an output that you can use with your municipality to demonstrate your environmental stewardship.

The calculator is designed to calculate evaporation and carryout and the probable range of reclaim water being used in the car wash based on average values from the field research conducted by International Carwash Association in 2002 and 2018. 

Fill out the information below and click "calculate" in order to calculate your Evaporation and Carryout. Once calculated, use your browser's "Print" function to print the results or save as a PDF to your computer for emailing.

 

 

If either of the next two questions are marked as "Yes" then the water calculations may not be accurate, as you will not be measuring the water used only for the car wash portion of the facility.

Enter your date range for the period of time for which you are entering your data. Enter values in mm/dd/yy format.
