Median of all compensation (including tips, bonus, and overtime) by years of experience.
Water or Liquid Waste Treatment Plant Operators with more experience do not necessarily bring home bigger paychecks. In fact, experience in this field tends to impact compensation minimally. Respondents with less than five years' experience take home $35K on average. In contrast, those who have been around for five to 10 years earn a noticeably higher average of $42K. People with 10 to 20 years of experience make an average of about $46K in this role. More than 20 years of experience mean a somewhat bigger median paycheck of $48K, but it's not much more than what less experienced people make.
