I became curious today as to how much water I use in a day. So, I tried to calculate it. These are estimates only and don’t include a lot of things.
- Showers @ 2.5 gallons per minute * 10 minutes = 25 gallons
- Drinking @ 16 oz a glass * 6 glasses = 1.5 gallons
- Toilet flushes @ 4 gallons per flush * 2 flushes = 8 gallons
- Urinal flushes @ .4 gallons per flush * 4 flushes = 1.6 gallons
For a total of 36.1 gallons. Wow.
My shower says 3 gallons per minute max, and I don’t think I’m maxing it. And I have an older toilet that still uses a lot of water at home (5 gallons I think instead of <2 like the newer ones) and newer toilets at work (I think) so I took a weighted average.
