Water Hardness Map

Included with the map is the Industrial Water Softener Sizing Calculator

Use the below map of the United States to choose your region and calculate the appropriate industrial water softener needs for your facility. The water hardness map below indicates the hard water levels throughout the United States. These levels affect the size of the water softener you need to soften your water in industrial applications.

Choosing your region will pre-fill the industrial water calculator with your hard water level. Then simply add your flow rates to determine the size of the industrial water softener required.
