I live in Ireland, we don’t pay for water (or even waste water out like they do in Germany), but the rain has been non-stop this year with the gulf stream. I’ve also just intalled a water butt out of a 500l repurposed whiskey barrel (again, Ireland) so that also helps with not having to use the hose (they call it the hose pipe)

That’s what rain barrels are for

Collect the condensed water from the aircon.
