For communications needs there would be some form of closed-circuit ( incongruously also called Open Line) telephones at each major pumping or distribution center to keep in touch. there might be remote control devices akin to engine-room telegraphs as used on ships. I have seen one ( photo of a museum exhibit_ which has pump power settings on it- as opposed to engine speed commands, this was used with a hydraulic dredge. If only for safety reasons, someting like this, and an open line phone would be needed, also to protect things if things broke down., a rapid response would be secured in accidents- Major break between miles 4 and five- shut the system down on that end! . e.g.

What are the advantages of digital communications over analog communication?
Using analogue communication from a digital interface requires some kind of converter to convert your digital data into analogue before it can be sent. This data needs to be converted back into digital by the receiver. Hence a larger amount of work needs to be done. eg: the VGA cable used to connect a PC to a screen is a analogue cable. So all the video signals that are sent out by your PC are converted to analogue first. Hence there is a larger amount of work done. There is also a chance of data being lost during this conversion. If the source signal and the output signal are digital, then there is no conversion required and resulting work required is less. This also means that the receiver doesn't need to convert this data. Hence work done is less and data loss in conversion is also minimal. Although transmitting digital data over long distances also results in some amount of loss. eg: video signals transmitted through DVI or HDMI cables are purely digital. A PC or Blu-Ray player connected to a digital screen using any of the above interfaces doesn't need to convert the signal before sending it. Hence data loss is minimal and resulting picture is sharper and accurate.
