In Germany chlorine is used to treat water in the plant but it's removed before it goes into the pipe. There is a tiny residue but that's residue and not intentional to prevent issues with the pipes.

What does Germany use to manage microorganism growth in it's water distribution system? As I understand cloramine/chlorine is used to keep the small amounts of microorganisms that will always be present in water and pipes from growing into a problem while it travels/sits in the distribution system.

Thanks!

If there is residue of the chlorine then wouldnt there be residue of the harmful compounds it reacts to create?

Netherlands, Germany, Denmark, Switzerland, and Austria with Czechia and Poland also transitioning to a high source-water protection and multi-barrier treatment like ozone, UV, and carbon filtration system.

The ozone has similar concerns as the chlorine with the formation of potentially hazardous by products. Carbon plus UV is probably sufficient as long as you can guarantee the pipes are fine through the whole distribution system. We will see how that plays out.

It played out pretty will since 2016...
