I don’t understand how you can just leave the tap on–where does that water come from?
Is the water from your kitchen sink and your toilet the same water?
Is water really being “wasted”?

In the city I live in the water comes from 4 places. In the mountains to the west and south east massive water storage dams have been built that get filled by rain, there is a large river to the south that supplies some water it originates at a volcanic lake far to the south, there are also ground water wells that pump water out of , and waste water is also recycled back into the system. All these sources are fed into the water treatment plants and from there fed into the pipe network that supplies your sink and shower.
Some cities also have desalination plants to feed water in, but that is very expensive and the city I live in has sufficient water resources without it.
The used water here goes to sewage treatment plants that seperate the water from the waste and the water is discharged into the sea or piped back to the water treatment plant at the start.
When water is “wasted” it is the water sitting in reservoirs that is being wasted they are not unlimited supplies and only fill at a certain rate over time. Where I live we occasionally get water rationing orders when there is insufficient rain.
