You can't dump everything to the soil and say "that's your problem now, nature. Cope!".
As opposed to eg 'wasting petrol', where the petrol really is gone afterwards. At least it has been chemically transformed.
Nature couldn't care less. Nature works on much larger timescales than humans. It's the humans that are impacted.
Just like climate change, plastic, and all other environmental issues -- humans are paying (or will pay) the price, not nature.
If your waste water isn't treated, and is discharged to water ways as-is, the more water you use, the more dilute your pollution.
If you've got a septic system, I dunno? Probably doesn't help, but if your system is well sized, no big deal? Some of your outflow probably recharges aquifers, so it's kind of circular (although a lot of the outflow evaporates, so less directly circular there)
It's easier to process per litre, but it is easier to process in absolute numbers?
When they dilute at the treatment plant, they can use somewhat dirtier clean water.
So, the prices might not be rising that quickly for now, but sinkholes are giving us the warning.
Prices don't always point correctly, esp. when there are other economic and socioeconomic factors at play.
I wouldn’t worry about wasting it. We’ll die from something else long before water becomes an issue.
Similarly, that spring water has no use if you can't extract it and get out from the hands of capitalistic companies (cough Nestlé & CocaCola cough) which monopolize said spring and suck it dry without giving it to you.
Don't forget, Nestlé's CEO told that "water is something they package and sell, and that water is not a human right". So don't expect it to get that abundant resource and use it the way you wish.
So, water is precious. You need to be mindful about it.

With every 5L of water I can
So it's not not meaningfully wasteful. However, I can't turn off the water in the winter, because I feel very cold otherwise. However, this doesn't mean I don't waste any water or happy about what I'm doing. My only (half) relief is this water is somehow processed and reused by city for other needs, at least one more time.
