Chlorination & Drinking Water

Purpose of Chlorine

Chlorine is used for disinfection at each Public Water Supply within the Town of Southeast as it is at 98% of U.S. public water supplies that are disinfected. It is the only disinfectant available that protects all the way to the tap.

Chlorine Levels

Chlorine is applied at levels necessary to insure kill of bacteria, viruses and protozoa that are known to cause illness in humans. Chlorine levels leaving the plant are maintained at levels that ensure the distribution system is safe from regrowth of biological organisms.


Chlorine residuals leaving the plant vary from 1.0-2.0 parts per million. Sampling throughout the distribution system ensures that sufficient chlorine residuals are present for disinfection.

Taste or Odor

We realize that from time to time chlorine is noticeable to some of our customers. The chlorine taste or odor can be eliminated from your drinking water by placing a pitcher of water in the refrigerator for a few hours. If your water has a strong bleach odor on a regular basis, please let us know so that adjustments can be made.
