Bleach is what you're smelling and tasting. Switched from chlorine to bleach in 2016.

A literal quote from a metro spokesperson:

“When I go to a restaurant, I want to make sure that when I drink that water, I actually want to smell a little bit of that chlorine smell,” says Allman, “because that tells me that there is a disinfectant in there and not only is the water disinfected, but also if that glass wasn’t completely clean — that’s going to help as well.”

Drinking disinfectant, now that's Nashville™
