What does a water treatment operator do, and how do you become one?

Water and wastewater treatment plant and system operators run the machines that move and treat water. They typically need at least a high school diploma and long-term training on the job, and a state license is usually required; licenses have several levels, and employers may prefer applicants with a certificate or degree in a field such as water treatment technology.1 Under the federal Safe Drinking Water Act, every state must run a certification program for the operators of community water systems, or lose a fifth of its federal drinking water grant; the state sets the levels and exams.2

Each figure is the middle program in that state. Yearly earnings are the reported quarter times four, an estimate. Only programs approved for workforce funding are counted; other schools may offer water treatment operator training too.

Where the water treatment program numbers by state come from

Which water treatment programs are counted?

Programs each state approved for WIOA funding (public workforce funding under the Workforce Innovation and Opportunity Act), from the US Department of Labor's file for program year 2024 (July 2024 to June 2025), covering programs approved as of June 30, 2025. Each state keeps its approved programs on an eligible training provider list (ETPL).7 Schools that never applied for approval are missing.

What the figures for each state mean

Each figure is the middle program among those that report it: half did better, half did worse. Prices are what most programs cost if you pay yourself (the middle half). Earnings are for the second quarter after students left, times four. Where a figure is missing, the table says why: "Not reported", "Left out" or "Not enough data" (what each means).
