It sounds like you'd want something solar on the tank-side. Otherwise, you're
adding more maintenance to the system.

to add some level sensors in the tank to indicate when the tank is less than
1/2-3/4 full (something might be awry) and another when the tank is almost
empty to disable the (remote from the tanks, but located near power) booster
pumps to prevent them from running dry and possibly overheating.

Anyone know of a good source for some battery operated transmitters and
battery or wired receivers? These are rather slow changing signals, so
something that transmitted only at a change or had a transmit interval that
could be set to a long time would be better for battery life (but changing
batteries isn't that big a deal, just a pain).
