Median of all compensation (including tips, bonus, and overtime) by years of experience.
Water Treatment Plant Managers with more experience do not necessarily bring home bigger paychecks. In fact, experience in this field tends to impact compensation minimally. Folks with fewer than five years of experience take home $43K on average, and those who have worked for five to 10 years see a bigger median salary of $49K. Water Treatment Plant Managers who work for 10 to 20 years in their occupation tend to earn about $57K. Individuals who have achieved more than 20 years of experience don't seem to earn much more than people who have 10 to 20 years under their belts; the more senior group reports an average income of $61K.
