I have to pay zero attention to water conservation. Hell, when it rains a lot I have to let some faucets run. Just pumping water from one side of the house to the other. Otherwise the side with the well can get moisture in the basement
Even in the rare densely populated areas where wells were common, there's not many left.
Most people in my area just hook up to city services instead of sink more money into their systems for substantial repair. I don't think there's many others left at this point, except maybe the 100+ year old houses whose plumbing wouldn't survive modern pressure.
In rural areas where that's not an option, your issue doesn't exist.
Not like if it's a big deal, but if we're gonna be pedantic, then we can't go halfway.
