I'm starting work on a community garden for our church.

The first thing is I need to check out an old but maybe useable well. We have
good, 2" outflo at the 2hp pump pipe.

Is that all I can do to test it?

The reason I'm asking is we're going to need to run the water about 400'
across yards and driveways. If it's worth doing that, then we can proceed.

If not, we won't be able to handle the project for lack of water.

We could drive a well close to the project, but then we'd have to run 300
yards of electrical to the site, which might also be a "deal breaker".


You should test it at whatever flow you think you will use and make sure it
doesn't go "dry" after some limiting period of time. Then, make sure you use a
big enough pipe to the garden to avoid pressure loss limitations.
Going under driveways may be a problem if you have hard clay or rocky soil.
Otherwise, you can tunnel under them using water pressure. Make a rig as
described in http://bradyproducts.com/documents/wellinstallation.pdf and use it
horizontally from the ditch you dig to go under drives.
