After doing some testing, I came to the conclusion that Epanet Z
cannot be used on a reliable basis. First of all, the author of the
software didn't put in any modifications since quite a few years,
which means that the code is probably outdated when it comes down to
accessing the Google Maps, Yahoo Maps, etc. satellite imagery.
Daniel, thanks a lot for your help. I guess I'm not going to worry too
much about the scale of the layout plan, as long as the pipe lengths
are ok and that you can easily locate the points with the general
features of the landscape/community.
