Thanks everyone for all your reassuring replies.
When I first came to Symi 20 years ago, we only flushed the loo when we had washing up water left over, and we only washed up when we'd washed ourselves in it first...in fact we had probably washed a vegetable or two in it before that! It was all part of the adventure, but I'm glad that things aren't that bad these days.
I returned for the first time last year and there was plenty of water at the Taxiarchis, but on Adriana's blog recently she mentioned water being rationed to 3 days a week in Chorio due to problems with the desalination plant. With so many rooms to cater for I'm glad to hear Frank has big tanks!
I'm really not too worried.. like you say Snoopy, there is the beautiful warm sea to swim in. Can't wait!! and don't worry Sugardens, I was only joking about the wet wipes and you're right to mention the problems they cause.
