How do restaurants use water in places without safe-to-drink tap water?

860 views

In most places in the world, tap water is not safe to drink out of the tap, and thus,not safe to wash vegetables for salads, make ice, etc. So in these countries, does every restaurant have a filtration system? Do chain restaurants have filtration systems? Or is the tap water just used regularly? I know it’s dumb but it’s one of those things I just don’t get.

“Safe” is an interesting choice of word. Safe for Americans and safe for the local population is different standard. Our system is not used to the local biome in many places, and that’s why drinking their water makes us sick, but it’s perfectly safe for the local population

Most places where “It’s not safe to drink”, really means – it’s not safe for people acclimated to pure filtered water, and not acclimated to a local condition.

All of these places where Americans “can’t drink the water”, well – the locals drink that water all day long.

So for starters, the number of places with legitimately polluted and unsafe drinking water is much smaller than you’re thinking.

Secondly, unsafe water can often be made safe by using water filters. Many restaurants, even in western countries with “safe” water still filter it for taste.

For a couple hundred dollars anyone can get a low volume drinking water reverse osmosis system with a 4 gallon tank. I have one in my house.

It costs between a few thousand and about $15 thousand for a full business high volume reverse osmosis system with water tank. These pull all the bacteria and all the contaminants out of the water and make the water taste exactly the same in every location. Almost every business that provides drinks to their customers has either a reverse osmosis or large filer system. Very tight volume businesses have many of these.

Reverse Osmosis is actually how most bottled water and other bottled drinks are made. They are really just tap water or well water that has been “filtered”.

Idk why everyone is answering to the affirmative, you frequently get sick when travelling, there’s a reason when you go some places that you get vaccinated and take cholera vaccines etc.

as a converse argument every commercial kitchen I’ve worked in DOESNT have a filter installed and even if they did it certainly wouldnt be high enough grade to prevent common water borne diseases, in se asia, africa, and mexico for example you need special treatment for that. Chlorine, u.v. ozone, something.

Having made the mistake of drinking a soda with ice in Cozumel, it’s not always taken seriously.

Eh, I’ve eaten at restaurants where I’ve watched them wash off the dishes in the gutter after a strong rain. I never got sick from that place. It sort of depends on the country and where you are inside that country.

When I lived in that country I had a home water filter that boiled and condensed the water like 7 times while filtering it. In another country I lived in we used iodine tablets when soaking and washing vegetables. I guarantee no restaurant in that country did that.

Yes I’ve had a lot of food poisoning.

Depending on the definition of “not safe to drink”. Often those tap water is just a boil away from being safe to drink. The cooking process is equivalent to the boiling process
