[sparkle clean]

hello all,
just wanted to put a question to you.
i am looking at storing and selling pure water to window cleaners in the plymouth area. my thinking is there is nothing more annoying when you are out working, and you are running low on water you know you have a few jobs left to finish your day and your not going to have enough water, now that means you are ethier going to have to go home and fill up, or play catch up tomorrow!!!
i think it would be a good idea to have somewhere you could fill up in no time and be back working again in about 30 mins.
what do you all think?
all comments gratfully recived!!!!
