Drinking Water Treatment

Fort Wayne City Utilities' primary commitment is to the health and safety of our customers.

We value your trust and we are committed to providing safe water that you and your family can rely on.

City Utilities uses the following chemicals to clean and treat our drinking water.

  • Ferric sulfate and polymer -- these chemicals cause soil particles and other dissolved and suspended particles to stick together forming sticky clumps that settle out, taking physical contaminants with them. These chemicals are added then completely removed during the treatment process.
  • Calcium hydroxide -- also known as "lime", this softens the water by causing naturally occurring calcium and magnesium to be removed.
  • Powdered Activated Carbon -- similar to charcoal, this is added to the process then removed, taking taste and odor with it.
  • Chlorine – this includes free chlorine and chlorine dioxide used to kill bacteria. It is measured in parts per million (PPM). The Environmental Protection Agency's upper limit for chlorine is 4 ppm. Water leaving the filtration plant must contain at least 0.5 ppm to stop bacteria from developing in the water main system.
