The tall white cylinder is the new carbon dioxide tank.

The Defiance Water Plant’s Granular Activated Carbon (GAC) Project is finally underway!

Crews from Peterson Construction have begun work onsite at Baltimore Road including relocating and replacing the Carbon Dioxide Tank, as well as beginning the construction of the basin that will hold treated water to be taken through the GAC filters before disinfection.

This new treatment will offer many benefits:

  • reduction of disinfection by-products such as total trihalomethanes (TTHM’s), which is the source of the violation letters that the City has sent out over the last couple of years;
  • provide a barrier for algal toxins that could be produced by algal blooms in the reservoir;
  • improvement in the taste of our water, and;
  • removing the compounds produced by algae that create taste and odor issues from time to time.

The system is scheduled to go “LIVE” during the winter of 2021-22, and we are looking forward to it!

This is just one more exciting project happening in our great community!
