Come the drought order if you can't use a squeegee you'll be out of work. After the last drought the regulations were changed so if another comes along the water companies will have much greater powers to prevent us using our systems. The only alternative will be to trad the work until the drought order is lifted.
And before I get shouted down, it isn't a viable option to ignore the order, it's legally enforceable so to carry on WFP after the water companies have obtained their drought order will result in prosecution and fines, just the same as if you were caught using a hose pipe to water your garden.
I'm talking about a full drought order here, not just a hose pipe ban
