Per person, I’ll give her 8 gallons per day for toilet flushing, another 10 for a shower, a gallon for drinking, 4 gallons for dish washing and food prep, 10 for laundry. I’ve probably left stuff out, but that’s only 33 gallons. So I’ll give her 75 gallons per day, per person; that seems generous if she’s ripping out her lawn and trying to conserve. And yet her family uses more than twice that. And they’re in conservation mode, previously using at least 300 gallons per person, per day.
