This must be the most incompetent group of "professionals" in charge of that water system.They are unaware that the water of the space station recycles 100% of all their water (no details should be necessary)?
They are planning to waste, literally,a month's supply of water for a medium sized city.
And here I thought there was a drought problem in the Western U.S.
Well it is Portland, so we know most of the water wouldn’t be used for showers.
