When the cable breaks you then loose all upstream sensors. Pipes sometimes explode, waterways burst. So it isnt ever just one cable. You need many levels of backup and as a general rule want the data moving on a network not folowing the pipe.

You could use a bidirectional ring network and have ptp wifi (canals tend to be mostly straight) as a back up and use GSM or sat phone as a tertiary backup.
