"People still drink chlorified water and governments still are too lazy to use a biological cleaning process all over the world..." What biological cleaning process are you referring to? How does it prevent bacterial growth in the water distribution system?

Microscopic chloroforms. I’m pretty sure they’re related to midi-chlorians. </joke>

  Thank you for telling everyone that you are not even remotely involved in water treatment, especially for those that are. No matter the treatment method, absolutely purified water can encounter pathogens. The water treatment process uses various methods to make water safe for consumption but the distribution system requires a residual for any biological contaminants that can enter, or be harbored within, and low concentrations of free chlorine (<2 ppm) provide that while carrying very little risk. Especially compared to most risks in modern life, like being in a passenger vehicle. Safe drinking water, partially due to chlorination is the greatest public health achievement of humanity so far. You are spreading misinformation.

    It was low-quality humor. I figured the midi-chlorian reference gave it away, due to the high density of Star Wars fandom on this site. Sorry to trigger you. I added a joke indicator, and I hope your blood pressure will decrease. https://www.starwars.com/news/so-what-the-heck-are-midi-chlorians https://www.starwars.com/news/so-what-the-heck-are-midi-chlo...

      It was obvious. Don't waste everyone's time talking way outside your level of expertise and then trying to make jokes when you're called out. It's juvenile.

        Man it seems like you’re having a rough week. I hope you can enjoy your weekend! Cheers.

        Thanks and I was, I'm sorry that I acted like that.

        It was CookieEngineer who made the original comment about something to do with biological cleaning of water. You may have caught that, but it was Tomcan who made the "joke" comment. I just read it as they responded to your question, but added the terrible humour to imply that they didn't take it seriously.

This [1] and [2] are a pretty good primer on how Kläranlagen are built in Germany where we use a biological water treatment process and are recycling 96% of sewage water. The remaining ~4% (the Schlacke) usually are used as fertilizers for farming or are burned in biogas energy plants. The latter happens when the quality is not good enough or the sewege plant doesn't have a stage 4 filtration system. The German wikipedia entry is actually also pretty good [4] [1] https://umwelt.provinz.bz.it/wasser/wie-funktioniert-eine-klaeranlage.asp https://umwelt.provinz.bz.it/wasser/wie-funktioniert-eine-kl...

  That's a sewage treatment plant treatment process. We don't typically drink treated wastewater, but some places recycle the water after a intensive purification process. Chlorine in drinking water treatment is used for disinfection and a small amount is added after treatment to keep bacteria from growing in the distribution system. Your information is not really relevant but interesting.

  Admittedly I don't read German, but I read the translated version and ... it looks very much like a typical sewage treatment plant in the US? What's unique about it? Not adding any chlorine is an interesting choice in any case, you can start out with perfectly pure water and still end up with contamination along the way to your tap. A tiny amount of chlorine prevents that, and it evaporates quickly after the water leaves the tap.
