I have a soaker hose on a large raised bed which can be very dry because of surrounding large trees. The clematis and honeysuckles in that bed need damp roots so when the soil is dry an inch below the surface the soaker hose goes on for an hour in the evening a couple of times a week.
I also water runner beans and sweetcorn copiously as we're on very free-draining loam and if I didn't we'd have no crops.
Otherwise regular frequent waterings are for new plantings only (particularly trees and shrubs), and plants in pots and containers - oh and the grapevine in very dry spells.
We have water butts on the house downpipes, but have to use mains water for the soaker hose and sprinkler and yes, we are on a meter, but gardening is my hobby. It still costs less than a gym membership
