The odd thing is that the city thinks it's worthwhile to keep a steam turbine driving a 25hz generator driving a motor driving these pumps, when, presumably, there are a number of modern solutions. They could either replace the 25hz electric motors with a modern 60hz motor + gearbox, or a motor-generator with gearbox feeding the original 25hz motors, or a solid-state DC drive, or maybe diesel drive through a reducer.
