Haha I'm reminded of a small island I lived on for a bit off the southern coast of Chile. We had no motorized land vehicles, or running water: everything was ox-sled, or boats. Anyways, for water, we used wells which were often filled with frogs, bird poop, dead things. We added a small amount of bleach to the water to drink it. We would also carry old coke bottles to the beach (2 mile walk one way) and fill them with water as it ran off the side of the beach cliffs out of the water table. It was filtered naturally that way, and the rocks and ferns it drizzled down often filtered it a bit more. Now, the well water was disgusting of course ... but that fresh water that ran out the sides of the cliffs was the best tasting water you've ever put in your mouth lol.
Modern plumbing, access to fresh and drinkable water ... man it's such a luxury lol.
