I'm from the southeast of Brazil. Nearly every place has a water filter, separate from the normal faucet, for the drinking water. The water tank on buildings and houses is normally made of plastic, not wood (though in some buildings, it's made of concrete and part of the building's structure), but you never know if it has been left uncovered, or how recently it has been cleaned (and the plumbing, as far as I know, is never directly cleaned).
- newnewpdro 8y agoPlumbing in general is never cleaned and it isn't a problem as the water is moving. The main issue with water tanks is the water is stagnant and in warm/hot climates ideal for life. Nowadays it's very easy to add a UV light to the interior of your water tanks to keep the interior sterile.
