I have an idea regarding the hosepipe ban, as you know it does not effect all areas (mine included in Southampton) even though I’m supplied by southern water.
If this comes into effect then why not find yourself a friendly fellow w/c not in the infected areas and ask him if he would supply you with the water to carry on your business.
Of course you’re not going to travel all those miles to fill your tank up however, should you be caught using wfp your friendly mate (from the north or wherever) is going to vouch that you purchased the water from him therefore not breaking any hosepipe bans.
I’m sure you get my drift? Surely there is enough of us on these forums to help each other out.
