I wish I could offer better help (as my summer job working for a municipal Department of Public Utilities puts me near a lot of water and sewer pumps, gas meters, electric motors, monitoring equipment, sensors and logic systems, etc), but almost all of our technology hasn't changed much since the last system overhaul in the 1980s. We use a lot of analog paper recorders (for tracking data over long periods of time), simple digital readouts, and auto-dialers at remote pump stations to send data back to the control room.
