Revised Dates for Tampa Water Department Temporarily Converting To Chlorine Disinfection

This information is 5 months 4 weeks old and may no longer be accurate.

The Tampa Water Department is announcing the temporary switch to its water disinfection process to chlorine starting Monday, October 3 through Monday, October 24, 2022. This routine preventative measure had been previously delayed to accommodate construction-related needs at the water treatment plant. It was further delayed by Hurricane Ian.

  • What is happening: During this period, the department will use chlorine instead of chloramine (a mix of ammonia and chlorine) to disinfect the drinking water.
  • Why are we switching how we disinfect our water: This routine switch switch typically takes place twice a year and protects the quality of drinking water by preventing bacteria from occurring in our water mains and service lines. Temporarily switching to chlorine also offers a sustainable alternative to losing millions of gallons of drinking water by releasing water via the City’s hydrants to clean out the water lines.

Customers with a sensitivity to chlorine: Customers who are sensitive to chlorine may notice a stronger smell or taste of chlorine during this switchover period. To minimize this effect, the Tampa Water Department recommends:

  • Run the tap for a few minutes before using.
  • Fill a pitcher of water and let it sit for several hours to allow any residual chlorine to evaporate.
  • Consider installing a carbon filter on kitchen/bathroom faucets or shower heads or replacing existing filters with new ones.

Populations with special considerations: Individuals and business owners who already take special steps to remove chloramine from tap water, such as dialysis centers, medical facilities, and aquatic pet owners, will want to take the same precautions during this temporary switch to chlorine.
