you don't need to "save" water
yes you do, you need to reduce the amount of water that gets dumped into the sewage system, because all that has to be treated before it's released into the sea/river.
Likewise all the fresh water has to be treated and pumped to your house
None of this is free, so the more you waste, the higher everyone's bills would be. This is the same Leftist thinking in respect to niggers robbing stores, "it's OK because they are insured"
We're not running out of water.
