Median of all compensation (including tips, bonus, and overtime) by years of experience.
Water Treatment Plant Managers with a lot of experience do not necessarily enjoy more money. Survey participants with less than five years' experience report a median income of $43K, and earnings aren't much higher for respondents who have five to 10 years under their belts; respondents in the latter group report a median of just $46K. For Water Treatment Plant Managers, 10 to 20 years of experience on the job amounts to an average salary of $56K. Veterans who have worked for more than two decades do tend to make the most in the end; the median pay for this group is $60K.
