Hi there,
I inputted the following for water demand.

Activity level (population): Rural - 16,970; Urban - 7,085
Water Use: Rural - 57; Urban - 128

Result: 1,870,203
Manual Calculation: 1,870,207

Although the variation is relatively small, what may cause it?

Anabel,

If I calculate 16970*57 + 7085*128 then I am getting 1,874,170. Am I mistakened somewhere?

Oh yes, this is right, however, in WEAP, the result is less. May you kindly assist with why this is? My NRW is 25%. Otherwise, I have not managed to identify any other variable that may be causing this.

Anabel,

So are you receiving a water demand of 1,870,203 result in WEAP, versus the manual calculation of 1,874,170?

What is the supply requirement result?
