Daily Water Quality Results
Below you will find average daily water quality data for both of the water treatment plants servicing
the residents and businesses of Henderson and Henderson County.
The "untreated" is the water that comes into the plant.  The "treated" is what is delivered to your home.

Turbidity is a measure of how cloudy, or dirty, water is and is measured in Nephelometric Turbidity Units (NTU's).  The higher this number, the less effective the treatment plant will be without making changes.  HWU monitors the turbidity of your water on a constant, streaming, basis to ensure that the best possible treatment is being maintained around the clock.
Water Hardness is measured as calcium carbonate.  The degree of its softness or hardness can be seen in this scale: 0-75 = Soft, 75-150 = Moderately Hard, 150 - 300 = Hard, and >300 = Very Hard.
