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".
