"Crossing bridges before you come to them " comes to mind.
If theres a ban then its usually only the millions of people who water gardens and wash cars that are affected. Then they enforce not using water at night and have night inspectors going round listening to the waterpipes to see that its complied with. Then its switching the water off and just allowing a couple of hours a day useage, then its get the water bowsers out. So its a question of enforced degree. It doesnt happen suddnely.
Its not been a prob to me in the past years.
However I dont want to call down the wrath of the gods.
Its not a national prob. Wales and Scotland have 98% reserves whilst Kent has 30-40% so its not going to be the same for everybody.
You may have to adapt but I do not believe that you will have to cease trading.
Wonder what the car wash guys will do ? maybe we could sell them some of our waste RO water :
