On average we used 209 liters or 55 gallons of water per day, per student. Amazingly only about 5% of our use was for consumption (cooking and drinking), while 45% was for bathing. Even so you only averaged 10 minutes of shower time per day.
If we were to add irrigation the numbers would soar! One inch of water on 1,000 sq ft of lawn equals 623 gallons (that’s 2,358 liters). So how many square feet of lawn do you have and how many times per week do you water? It is easy to see how that 55 gallons per person can easily become 120-150 gallons per day. Irrigation is often 45-75% of our water use.
