ROI-​Calculator


 
Use the Zurn Water Usage Calculator to calculate your water usage savings.

 The table below provides an illustrative example of a typical office building setting with 100 occupants – 50 males and 50 females in a 260-day work year. The baseline calculation uses the EPA Act of 1992 for the gallons per flush/gallons per minute consumption.
