Question

how much of the total water is unit for domestic use?​

Answer 1

Answer:

Estimates vary, but each person uses about 80 – 100 gallons per day. The largest household use of water is to flush the toilet, followed by showers and baths. A typical family of four would normally use about 35 to 40 units of water or between 26,000 – 30,000 gallons of water per three month billing cycle.
