Water,,,is a serious topic (despite me takin th p!ss with my earlier reply!).
Maybe not so much for you guys, what with all them rocky mountains and snow you all got - but here we live on the driest continent on earth. The only people who use their potable water better than us is the Israeli's.
With the droughts we've been having, Capital city Perths water reserves were down to 18% of capacity - critical status...
Its so bad that in Perth - you are allowed to water your lawn once every 4th or 5th day for 30 mins depending on your house street number (odds evens etc) shown in the evening news each night for the following day - you break the rule - and neighbors dob you in - and the water nazi's come around and fine you big time.
Anyway - water restrictions here are a fact of life - but most folks still drink water from the tap (faucet).
Bottled water however is quite popular and all of it is marketed as "spring water this or spring water that" - most of it is bottled tap water!
A while back a few enterprising dudes started this huge water bottled selling scam where folks down our way in the high rainfall area would pay 4 or 5 grand to put in large water storeage tanks from their roofs. The rain straight off the southern ocean and lower west coast indian ocean was supposedly someo of the cleanest in the world yada yada yada.
The idea was that the co would "buy" this water and get milk tanker type trucks to haul this water to Perth and they would hire a bottling plant over weekends to bottle this water, and sell it thru supermarkets etc..
Naturally enough, when you realise what a bulky heavey commodity water is to truck any distance and what our fuel costs are with all the govt taxes in them - the project went belly up..
Lots of Farmers round these parts are still paying off their 20,000 Gal storeage tanks!

Most of em never even got to sell the first gallon!
My sis always buys "evian" brand a bottle water - like it's some kinda status symbol to be able to afford bottled water with a pale blue label and it's somehow 'chic' to be seen drinkin it.
Ever the down to earth type - I felt obliged to supply her a Choice magazine article where they analysed most of the leading brands and it was the exact same stuff comming out her faucet at home complete with flouridation and chlorine etc etc from the water treatement plant.
I also felt compelled to point out that spelled backwards - Evian water was pretty close to Niaive, which she musta been to get suckered into buyin it in the first place!
Me - I just drink the rainwater that falls from the sky...thats the best water I've come across...
Cheers!
