It’s very hard water in East Anglia where I live so water spotting could be an issue in warm sunny weather. In ‘normal’ years (no heatwave or drought), if my car’s dirty during the summer months and needs washing and it’s going to be a hot sunny day, I get up extra early so I can get it washed before the sun’s too high in the sky and at full strength so I can avoid water spotting issues. If for whatever reason I’m not able to work my car washing around the weather, then I’ll leave it dirty for a few more days. Although we don’t currently have restrictions on water usage because of the drought conditions (I think there’s been just one or two short spells of light rain in the last last two months ), my car’s not getting washed as often as it would normally be - IMHO there are more important uses for water than car washing, so the car can wait.
Water softener the house and innocently include the outside tap?
As has been said if possible I try to avoid the conditions that will give me water spots but if I do get them I use Koch Chemie FSE to remove them and also gives a good shine as well.
I use ONR to wash, and I wash and then dry one panel at a time. Water then doesn't sit on the car. Might be an option for you, I don't know.
With the M3 that you're working on, surely the Finish Kare Ultra would minimise/eliminate 99% of the potential etching from the water spots, if done straight after the wash, maybe?? I have a few good etched water spots in that crappy area where the boot meets the rear bumper. Used a DA with Meguiars compound and I can't shake them haha. I'm no pro though!

I'm no pro though!It's been in the paint a long time and there's a few deep bird etches as well, it'll be safe once it's corrected and waxed NI isn't too bad for hard water.

If so, do you have a site or something?
