Median of all compensation (including tips, bonus, and overtime) by years of experience.
For Water Treatment Plant Managers, experience does not seem to be a major factor in determining pay. People who have worked for fewer than five years bring home $43K on average. Median compensation in the five-to-10 year group, however, is higher at approximately $47K. Water Treatment Plant Managers who work for 10 to 20 years in their occupation tend to earn about $57K. More than 20 years of experience mean a somewhat bigger median paycheck of $60K, but it's not much more than what less experienced people make.
