Median of all compensation (including tips, bonus, and overtime) by years of experience.
For Water Treatment Plant Managers, level of experience appears to be a somewhat less important part of the salary calculation — more experience does not correlate to noticeably higher pay. During the first five years of their careers, Water Treatment Plant Managers see a median income of $43K. Survey respondents with five to 10 years of experience report an only modestly higher median of $45K. On average, Water Treatment Plant Managers make $56K following one to two decades on the job. Veterans who have acquired more than 20 years report a median income of $59K, which is generally higher than the pay reported by other tenure groups.
