Yeah! I know in some places 'rainwater harvesting' is illegal! Craaazy! But the tap water here in Ireland contains flouride, chlorine, and a million other chemicals, and is reported to be the most carcinogenic in the county of Donegal where I live... eeek! But 5L bottles of water cost 2 euro each, and we get through two of these bottles a day, so it would be very expensive to buy it. Isn't is the craziest thing that it's so difficult to get clean water these days?!
