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. Someone who has worked for fewer than five years earns around $43K on average. Individuals with five to 10 years of experience don't get much more, though; the average income in this group is $46K. The average pay reported by folks with 10 to 20 years of experience is around $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.
