You see, pure water is not a conductor, but what we have is not pure water. So, you can complete a circuit via water. Dangle two wires about the level, using a low voltage, and when the water in the sump completes the circuit, have it do something.



Then again, you don't have to worry so much about corrosion if the wires never touch water, so maybe.
