Why Is (Free) Water in Restaurants So Chlorinated ?

90% of the time I go to a restaurant for dinner, and I try the water that is offered for free, I find it chlorinated. So much that it could have been taken from the local swimming pool. Yet when I drink from the tap at home, the amount of chlorine is just noticeable.

Even at the restaurants close to home.

Do you think the restaurants add an "extra" amount of chlorine to the water, to make it not drinkable so that people order drinks with their dinner?

              @payless69: And you must have learned from a dodgy OzBargain textbook. A chemical being an element or not has no bearing on its taste. All that matters is if our smell and taste receptors can react to it. And we do have taste receptor channels for chloride ions.

        So you drink filtered water at home but you are wondering why the unfiltered water from a restaurant tastes like chlorine?

          Dear restaurants patroned by OP, please do OzB community a favour and significantly increase the chlorine in OPs water.

          Filters don't remove the chlorine. What may be causing the difference is that the restaurant water has the chlorine reacting with organic contaminants and it's the product of that reaction that's being tasted.

            Activated carbon filters will reduce the amount of chlorine byproducts, free chlorine and chloramine..the amount will depend on things like contact time and concentration levels.

    Because it comes out of the tap on the wall in the kitchen…

    It’s a ploy by big soft drink cartels to lace restaurant table water with chlorine to make you buy more over priced non-water drinks.

    • The water coming out of my tap ( kitchen, shower or outdoor ) is never as chlorinated as the one at restaurants

        If you are drinking chilled table water, this may be the problem as opposed room temperature water at home.

        Chlorine evaporates quite quickly and readily at room temperature in open containers. At the restaurant, they might bottle the water from a filling station and then seal it and put it in the fridge. This doesn’t allow any of the chlorine to evaporate and the cooling slows down the process.

        If you are drinking regular room temp. tap water and it tastes different, it’s in your head. There is no way on gods green earth are restaurants putting chlorine in their tap water to make it up drinkable just to sell you bottled water. That is some top tier tin foil hat shit right there.

        Chlorine is dangerous and corrosive to humans in the wrong amounts. The risks would be too great for a restaurant to let some minimum wage worker put chlorine in drinking water just to make their customers buy other drinks. There are other, safer things they could put in the water to make it taste like shit before they would go the route of putting a dangerous chemical like chlorine in it.

        If you are that concerned about it, bring your own water. Or better still, take a sample of their water and use a test kit on it. You can get kits that measure pH, chlorine, fluoride, copper and hardness.

        Or, you know, take your tin foil hat off, it seems it’s on a bit tight…

          They dont/didn't put fluoride in water in the UK, and yeah, they are renowned for having great teeth.

    • Also that the restaurant is paying for both materials and labour to facilitate this chlorination. :surprisedpikachu.jif:

    • I think we might have the common denominator with this one.
      Methinks it's not the restaurant in this situation.

  • It's toilet water, hence the extra chlorination ;)

    I've noticed this too. But I've also noticed this weird over-chlorinated taste from the laundry taps and the outdoor hose at home.

    Apparently the chlorine in the water supply can react with phenolic compounds within hoses to form chlorinated phenols. The characteristic taste is a bit like a band-aid. If a dishwasher (or washing machine), for example, doesn't have a backflow prevention valve before the hose, you can end up with this contaminated water in your drinking supply.

    Considering how many hoses are attached to random things in the front and back of a restaurant, you may have finally unravelled the mystery for me.

  • Fill a bottle with normal tap water. Put it in the fridge for a few hours. When you open the bottle, it will smell like chlorine.

    You drink filtered at home. Tap water from restaurants is unlikely filtered. Water temp also changes the taste and the biggest factor is in your head. If you care enough to drink filtered at home then for whatever reason I would expect you to notice a difference because it must matter to you. It's surprising to have stretched to thinking restaurants collectively and purposely change the taste of water, instead of any of the other reasons above. Just take your own bottle next time or buy a drink.

    • Maybe. I drink filtered water at home, and the missus always insists on taking water from home whenever we go out as she dislikes the taste of tap water. But I drink the filtered at home and am happy to drink tap water when we're out.

    Depending on location.

    There are chlorination plants to kill bacterial growth in the water supply. Check your supply authority for water quality and testing as well as results

    • This could also be a factor.
      Just because they live near these restaurants doesn't mean their retic water comes from the same reservoir supply or is the same 'age' from the last point of chlorination

      (Though most likely it's because the op admits to using a water filter at home, which is clearly going to produce a difference to the resulting water taste)

      • I noticed the quality level of tap water changes when I was brewing my own beer.
        After long periods of no rain, the brew would hardly progress. Filling up after big rainfalls, and the brewing was faster.
        Filtering the water did result in better brew, and water from the 20L bought from W did lead to the best results.

    According to this the Australian guidelines says there shouldn't be more than 0.00015% of chlorine in the water

    Would that really be able to be tasted or would the taste be the types of glasses or not being washed from dishwashing soap more likely?

    • +1

      Yes I think you are on to something.

  • +1

    Could be that the restaurant you visit is closer to the chlorination source than your house. Or that you drink filtered water at home, so there's a huge contrast when you visit a restaurant. Could also be something as simple as venue change. You're in a different (presumably fancy) environment so your senses are more sensitive to taste.

    • I was living for 20 years on the side of a mountain, where the only water available was the one coming out of the mountain ( of course filtered but probably as good or better than the one you buy ). It was not possible to pump it up from the lake. So maybe I have developed a "taste" for clear water.

  • It's a big conspiracy to make you buy the bottled or sparkling water, or to push alcohol sales up

  • +1

    Just unfiltered tap water.
    I use a filter jug at home to get rid of excessive chlorine and microplastics which are in abundance in tap water. Just take your own water bottle with you.

  • It's not. You, like me, are just so used to drinking filtered water than when you have the tap variety from a restaurant you really feel the burn.

  • Take the chlorine home and soak your free woolies shopping bags and get triple the refund!

  • on the subject of filtered water, sis in law has one for their shower, when we stay at theirs my skin is noteably less dry and softer

    I did consider getting one but at 6k just to filter the shower, id rather spend 2k and diy and filter everything coming in the house but I would need to look into it more

  • I think it’s often because they leave the water standing for a while in metal jugs. Seems to taint the taste a little.

  • confirm they add chlorine, they also don't bring water out on time/at all deliberately so you are forced to buy a drink, the food is laced with sodium to keep you drinking and spending more.
