FAQs about WEc1 :

Can non-potable well water that is used for irrigation contribute to potable water reduction?

Can surface water, such as water from an irrigation ditch or a local creek, be used as nonpotable water?

Do interior planters count in the calculation?

We are using non-potable water for irrigation. For drought conditions, can we hook up to a potable water source for backup and still earn this credit?

Water Efficient landscaping - finding the ETo

How can I find the evapotranspirtaion rate, ETo, for various plants in various regions, and can this be found on LEEDuser's website?

Yes, LEEDuser lists Resources within the tab above that provide that data.

there were no references indicated "Evapotranspiration (ET) rates vary greatly regionally and seasonally. There is no comprehensive single reference point for national ET data. "

This website will rock your world: http://www.iwmi.cgiar.org/WAtlas/ If you enter in the project latitude and longitude-easily taken from Google Earth--it will give you the ETo for pretty much anywhere on earth.

A note of caution: I just checked the online model from the website above for a few locations in Morocco, and the data on precipitation and temperatures is significantly off. I'd make sure the rest of the data (precipitation, temperatures etc.) checks out before I used the ETo values proposed by the model.

Daniel is correct in his caution. The website does not contain long-term averages & is based on the last year of actual data only & is intended for real-time agriculture use. Sorry for the bum steer.
