Miami-Dade Water and Sewer Department to change water chlorination method for two-week period

MIAMI (October 28, 2015)

The Miami-Dade Water and Sewer Department (WASD) will change its method of chlorination at each of its regional water treatment facilities for two weeks, beginning Monday, November 2 and ending Sunday, November 15. Specifically, free chlorine, instead of the standard combined chlorine (chloramine) will be used during the treatment process.

Free chlorine is considered an effective method of cleansing water distribution systems. This routine procedure is regularly scheduled each year in a partnership with the Miami-Dade County Department of Health and the Department of Regulatory and Economic Resources (RER).

County residents may experience some chlorine smell and/or taste in their water during this short-term period. This is normal as free chlorine has a slightly different taste and smell than combined chlorine. The temporary change does not cause adverse health effects and is a necessary part of WASD’s ongoing efforts to provide safe drinking water to Miami-Dade County residents.

It is the priority of the Miami-Dade Water and Sewer Department to provide safe, reliable service to its customers. For additional information about Department services and programs, visit
