Why does the water have a “chlorine” smell in the winter time?

MAWC adds chlorine to the drinking water to prevent water-borne disease outbreaks such as cholera, typhoid, giardiasis, etc.  The chlorine must remain in the water for its entire journey to your spigot.

In the summertime MAWC combines ammonia with the chlorine to help carry the chlorine over the entire distribution system and reduce taste and odors caused by the warmer water.  In the winter, MAWC eliminates the ammonia and adds only chlorine to the water.  This chlorine eliminates any free ammonia in the system which left unchecked can cause bacterial growth.  This “free” chlorine residual creates the off odors that you smell.
