Hi Ya, hosepipes are banned on our site as well. The use of them encourages more use of water than required and some used hoses to fill water butts with them as spraying plants with cold water is apparently detrimental, it's like you being doused with cold water when warm so they tell me. We do have dip tanks and I have seen one use one of those wheel barrow things you fill up and he does it several times. I don't like dip tanks myself as I think others have dipped in there with weed killer, soil (it could contain disease), so I tend to steer clear but this year my butts are nearly empty so when needs must.
