Greywater potential- How much greywater do you produce?

•Top Loading Clothes Washer: 30-50 gallons per load
•Front Loading Clothes Washer: 10-20 gallons per load (older models use more water than newer models)
•Shower: Depends on shower time and shower head- a low flow (2.5 gallon/min) for 10 minutes is 25 gallons. There are 1.6 gallon/min shower heads available, and even 1 gallon/min heads.  You can reduce your shower usage by 50% by installing and using a shower shut off valve. We highly recommend it!
•Bathtub: 30-40 gallons per bath
•Kitchen Sink: 5-15 gallons per person per day
•Bathroom Sink: 1-5 gallons per person per day
