Chlorine Disinfection

Temporary Change in Drinking Water Treatment

Tampa’s drinking water is treated to produce high-quality drinking water that meets all federal and state drinking water regulations.

The Water Department primarily uses chloramine (ammonia added to chlorine) to disinfect the water. However, we switch to chlorine disinfection several times a year, usually in the winter and summer. Chlorine is a strong disinfectant that kills bacteria, helping ensure that the water remains safe to drink as it travels through the water mains and service lines to your tap. This temporary change in disinfection method lasts for three weeks at a time.

We work closely with the Florida Department of Health (FDOH) to ensure that we comply with EPA guidelines for using chlorine and chloramine to disinfect Tampa’s drinking water.

The next routine change in our water treatment process is scheduled for September 7-28, 2021.
