i collect rainwater from an improvised rig at my place here on the edge of nowhere, then i filter it with charcoal and a kitchen towel paper plug in a funnel

i don't trust the water, and i should say that they seem to chlorinate the water less here in madeira, but i don't trust the fluoride part, that's why i generally don't drink from the municipal water. except the one next to the church, because that's at the top of the hill and no point carrying water just for one sip once a day
