Oddly enough, it may depend more on the air environment near this valve than the water environment through the valve.  Sewage gases corrode wiring so fast, maybe I would consider an air-operated system.  The actual valve type depends on on/off characteristics, if it is needed for regulation of system flow or pressure, etc.

but if its a sewage treatment plant for a residential area, where i imagine its a practically safe area from corroding gases ( I assumed only the formation of CO2 gases from the plant) because here in India most of the population choose aerobic bio treatment than anaerobic. Lets say for controlling just the flow in a pressurized line . would you suggest a air-operated butterfly valve or a electrically-operated system?
