I mean, that’s a thing in areas of the US too. I’m in the US and where I live it isn’t unusual for people to have safe drinkable freshwater springs just spontaneously pop up in the middle of their yard. You can drive a sandpoint basically anywhere around here and get practically drinkable water. I say practically just because, legally speaking, potable water wells still need to be drilled far deeper than a sandpoint. But if you actually test the water coming out of most sandpoint wells in the area, odds are it would test perfectly safe provided there’s no farm runoff there or something. So in my area the water conservation marketing falls just as flat.
