Wastewater operators are the unsung heroes of public health and environmental protection. Every time you flush a toilet or pour something down the drain, a wastewater operator is working behind the scenes to make sure that water is cleaned, treated, and safely returned to the environment.
If you’re curious about starting a career in the water and wastewater industry, becoming a wastewater operator is one of the most direct and rewarding paths. In this article, we’ll break down what wastewater operators do, how much they earn, and what a typical career path looks like.
Job Duties of a Wastewater Operator
Wastewater treatment operators work at municipal and industrial plants to ensure that wastewater is properly treated according to environmental and public health standards. Their responsibilities include:
- Monitoring flow rates, chemical dosing, and biological treatment processes
- Inspecting pumps, valves, filters, and clarifiers
- Collecting and analyzing samples for BOD, TSS, pH, ammonia, and other key indicators
- Adjusting equipment and treatment levels based on lab data
- Logging operational data and reporting to regulatory agencies
- Performing preventive maintenance and responding to alarms or emergencies
- Following strict safety and compliance protocols
Operators typically work in shifts and may be required to respond to after-hours emergencies or on-call rotations, especially at smaller facilities.
Education & Licensing Requirements
Becoming a wastewater operator usually starts with a high school diploma or GED. From there, most states require operators to be licensed. Licensure is generally structured in classes or grades (e.g., Class I to IV) based on the size and complexity of the facility.
Typical Requirements:
- High school diploma or GED
- Pass a state licensing exam
- On-the-job training hours (may vary by class level)
- Continuing education for license renewal
Some operators pursue associate degrees or certificates in water quality management or environmental science, but these are not always required.

Wastewater operator salaries vary depending on region, certification level, and facility type. However, the pay is competitive for the required level of education and experience.
- Entry-Level (Class I): $40,000–$50,000/year
- Mid-Level (Class II–III): $50,000–$70,000/year
- Senior/Chief Operator (Class IV or Supervisor): $70,000–$90,000+/year
In some regions or high-demand areas, licensed operators can earn even more, especially if they hold multiple certifications or supervise large teams.
