Operators

Operators Everywhere are Helping Water Utilities Protect Public Health

Certified operators are a critical part of providing an adequate and safe supply of water.

Operators are typically responsible for a variety of tasks centered around operating and maintaining a system or plant. They typically work in a selection of capacities: water treatment, distribution, water collection, or wastewater. 

AWWA has a large number of resources devoted to helping individuals become a certified operator, as well as materials to help existing operators advance their career.

The Operator Career

Operators can work in various areas, such as water, wastewater, distribution and reuse. These operators maintain equipment and processes to monitor and affect water as it moves through the treatment and distribution cycles.

Becoming a certified operator also offers individuals the opportunity to make a difference in society on a daily basis. Clean and safe water is essential to everyday life and operators have the ability to regularly impact that need.


 

Stats About the Career

The operator career is a promising and stable field. The US Bureau of Labor Statistics estimates that in 2016 there were 119,200 water and wastewater treatment plant operators in the United States. In general, jobs within the water industry remain relatively less affected by changes in the economy than other industries. Additionally, the US Bureau of Labor Statistics maintains that in 2018 the average salary for water and wastewater treatment plant operators was $46,780 USD per year.

"Why I Became an Operator"

“I became an operator first and foremost because of my love of the environment and desire to be a part of protecting it." 

I love helping the people of NY in this capacity and look forward to explore other opportunities with them in the future or any other utility that will allow the opportunity for advancement.”

“I like the thought of the stability, the serving my community aspect, the pay, vacation time, and being able to retire at 55.”
