TOTAL  
Directions: The waterusing items are listed in the lefthand column. The use rate per person per day is shown in the next column. The third column is filled in with the flow rate. For example, the rating of gallons of water used per flush and the rated flow rate on the showerhead would be entered in this column.
Multiply the second column times the third column then times the fourth column (this is the number of persons in the household). The subtotal for each item is entered in the fifth column.
The figures in the fifth column are added up to show the amount of water used each day. This total can be multiplied by 365 (days) to give the amount of water that would be consumed in one year.
(We plan to make this an interactive form in the near future. Sorry it's not yet!)
