Use the rainwater from your house roof, you can get an adapter which fits
onto your downspout and directs the rainwater into a water butt....the ones
I've seen don't allow the butt to overflow and re-directs surplus water into
your drains.

Phil, OP mentions NOT having room for a water butt .........

I wonder if boiled (then cooled!) water would do ?
Or maybe water sold for irons?
