tap water.......FREE

[Midnitemo]

take a berky with you or construct yourself a mini berky using just 1 candle.....fill it when you get in the bunk wake up to filtered water in the morning...single candle is about £10-£11 couple of cheap pails maybe £3 each et voila.....draw your water from service station's personally I'd be more than happy to drink water from a garage forecourt in this country (and did when I was a truck driver) not so in Europe though as a lot of tap sources are non potable(not for drinking)
