What's happening in your world?

I noticed that about American/Canada! It seems whenever I see a reference to a country water supply it's well water!

I think maybe other countries too? In fact maybe Australia uses roofs/tanks to collect water more than anywhere else???
I had wondered about that a lot, as it seems to me logical to take advantage of the fact that rain is going to fall on your roof anyway, and most (well built) structures are going to make provision for collecting the water and taking it away (gutters, downpipes).
I think a lot of countries would at least have used 'water barrels' at the downpipes in the past? That would be ok in areas with regular rainfall (but still wouldn't hold much water......I guess people washed less back then!), but in many areas rain falls all in one hit and then there's none for ages. Hence the big rainwater tanks (the more variable the rainfall the bigger the tank/s required!)

I would rather use rain then ground water as it seems cleaner (if you have a good catchment system), well at least I know what's in my tank water! (ok it's not exactly sterile....!!)
