We are having difficulty figuring out what the following review comment means.
"Provide calculations to confirm the quantity of nonpotable water used for irrigation (52,148.46 gallons in July.) The number they provided in parentheses is from the table in our template and is the result of the standard calculation. What other calculation could they be referring to? We are confident we have achieved this credit by using only purple pipe reclaimed water and rainwater which is collected from condensate, Winter rains and Summer monsoons and is stored in a 52,000 gallon tank.
Perhaps it means they want calculations illustrating that nonpotable water systems support the quantities entered in the table. Any std. means to do that?

Yes, you are expected to demonstrate with calculations the figure you entered in the cell "Nonpotable water used (gal)".
I think you have to investigate available purple pipe reclaimed water and rainwater during July.
I hope this helps.

Gustavo is correct. You need to demonstrate through calculations that the "available" reclaimed water and rainwater meets or exceeds the demand. "Available" is the key word. What the reviewer is effectively saying is that the tank size doesn't necessarily equate to available capacity at a given time. Despite the tank size, it's possible that the needed capacity for the irrigation demand is not available in the storage tank.
