Hose ban, April 5th

Looks like I’m in line for a hose ban from April 5th, being in the Thames Water area. (Not the only area). So what do I do to plan?

I already have a hose which goes right down the garden to the water butt at the bottom. This is only to fill the butt, which then serves a trickle system which varies from year to year, but puts the minimum amount of water in the right place.
This saves me carrying cans, which I can’t do much of.

I have another butt which was intended to catch rain water, so I must fix that up
And………I need loads of mulch.
I may not grow everything I was going to.
What else?
