Email the water hauler URL for endless

Actually, we decided (three of us anyway) that we'd do exactly
what you suggested, which is to line up, for emergencies, a price
sort of what the SPUG group does for us for propane:

What we'd do is negotiate a set price and delivery conditions,
and then we'd let all the neighbors know.

At the very least, we'd rate the bulk truckers, as some of them
are downright nasty. Most (if not all) take days just to return
a call, and none seem to have a 9 to 5 office admin. So, you
always get an answering machine. All who called back said they're
swamped now.

Even the big San Jose Water Company told me they're almost out
of water meters, which is what you need to legally hook up to
a fire hydrant to get water at 1 cent a gallon.
