Clean water doesn’t just happen; it’s made possible by skilled workers behind the scenes. Water treatment operators help protect public health and the environment, and many start this meaningful career without a college degree.
Water treatment operators control systems and equipment that clean, treat, and distribute water or wastewater. Using computer systems, gauges, and mechanical tools, they ensure the water we drink—and the water we flush—meets safety standards.
Job titles include plant operator, wastewater operator, process operator, SCADA operator, and water treatment plant operator, but all play a role in keeping vital water systems running.
You don’t need a four-year degree to become a water treatment operator, but you will need technical training and a state license.
Here’s how to get started:
Earn a high school diploma or GED: This is typically required for entry-level roles or certification programs.
Take a water/wastewater operator training program: Offered at community colleges or technical schools, these programs cover system operations, safety, chemistry, and environmental regulations.
Start working in a trainee or assistant role: Some municipalities or utility companies hire entry-level operators and provide on-the-job training.
Pass your state certification exam: Most states require licensing at one or more levels. Certifications typically include written tests and continuing education requirements.

Licensing levels vary by state and facility type. Most states offer multiple grades based on experience and system complexity.
Understanding Supervisory Control and Data Acquisition (SCADA) systems is helpful for operators using digital monitoring systems.
Some roles require OSHA, confined space, or chemical handling certifications, depending on the treatment process used.
