The chlorine in water will evaporate into the air if left in an open container; Pour yourself a glass of water, and let it stand for 30-60 minutes. It should then taste a LOT less Chlorine-y. Even in a sealed container you shouldn't be able to taste it after about 3 days. This is why water from a mains pipe tastes of chlorine, but the same water pumped into a water tank (for heating etc), doesn't.
The water is completely fine here. I'd not blame anyone for using a brita filter or something to save the kettle - but you're just throwing away water and energy on bottled water...
YM2: Our water is so hard, it beats up little old ladies for their grocery money.
YM3: Our water is so hard, it beats up the cops that come 'round to take the report from the little old lady.
YM4: Our water is so hard, I once got arrested for assault with a deadly weapon, by a bunch of beaten-up cops, for holdin' a hose in me own garden.
YM1: I used to carry a chisel round in my pocket, in case I got thirsty.
YM2: I once forgot my chisel, had a drink anyway, and broke all my teeth off.
YM3: We only 'ad one chisel for all of us, and we had to trade it off between the kitchen faucet, and breaking up the toilet water into pieces small enough to flush.
YM4: We had to rent our chisel, and on days when we couldn't afford it, we had to follow cops around and drink their broken-off teeth when they got beaten up.
I used to live in Leeds and used the water for a few gardening projects were the PH of the water was very important so was also testing it, it was always perfect, never had to modify.
Having lived in London most of my life, and spent a few years in the US (MI), I can tell you we've got it good. I used to use bottled water in the US as I didn't enjoy drinking chlorine flavour/smelling water...
