I'm using the Outdoor water use reduction calculator_v02 from the resources tab since the project its outside USA. I'm entering the data for the monthly rainfal and Monthñy ETo from the IWMI site.

I it ok that the table in the calculator is showing negative numbers in the water demand column? 

the rest of the results, such as peak watering demand, peak watering month ETo, LWA and LWB are positive numbers but I'm still concerned with the negatives of the water demand column
