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

(MIAMI, October 25, 2012) – 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, Nov. 5th and ending Sunday, Nov. 18th. Specifically, free chlorine, instead of the standard combined chlorine (chloramine) will be used during the treatment process.

In a partnership with the Miami-Dade County Department of Health and the Department of Regulatory and Economic Resources (RER), WASD annually uses this free-chlorine treatment. This routine procedure is regularly scheduled each year, as free chlorine is considered an effective method of cleansing water distribution systems.

County residents may experience some chlorine smell and/or taste in their water during this short-term changeover. 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, potable 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
