Water Plant Operator License Information

Water plant operators must be certified by their states of employment. Most states offer four levels of certification and award them according to education, experience and plant size. Entry-level operators typically begin at the first level of certification, which requires a high school diploma, one year of experience and a passing score on an exam. Advancing levels require increasing hours of education and experience. Small water plant operators usually need only a lower level of certification that entails less experience and education.

Some states allow operators to transfer certification from another state; however, some may have to re-earn certification when moving to a new state. Widely recognized professional organizations, such as the Association of Boards of Certification (ABC), offer certification programs that are typically accepted by multiple states. ABC offers four levels of water treatment plant certification, which require a high school diploma, increasing amounts of experience and education. For example, a class four certification may require 1,800 hours of postsecondary education and four years of experience with two of those years in a supervisory role, as well as a passing exam score of at least 70%.

Formal Education Options

There are no formal education requirements for entering a career as an operator; however, employers favor candidates with an associate degree or certificate in water technology because they need less on-the-job training. These 2-year degree programs can be completed in community colleges and trade schools. They usually focus on fundamental treatment procedures, regulations and leadership skills. Courses may include laboratory analysis, quality monitoring, backflow procedures, equipment maintenance and supervising. While formal training prepares students for a career in water treatment operation, it does not necessarily provide state certification.

Other Qualifications

Since they control and maintain plant machinery, water treatment operators must be familiar with mechanics. The position requires computer proficiency and skills in chemistry, math and data analysis. Operators must be physically capable and in healthy condition because the position is physically demanding and often involves working with toxic chemicals in dirty, odorous and loud environments. Water treatment plants operate on a constant basis, so operators must be willing to work flexible and long hours including overtime, evenings and weekends.

Salary Information and Employment Outlook

The U.S. Bureau of Labor Statistics (BLS) predicts that positions for water and wastewater treatment plant and system operators will decrease between 2018 and 2028. This is about the same as most other jobs across the country. Also according to the BLS, as of May 2018 the mean annual salary for these positions was $49,490. The nonresidential building construction industry currently pays the highest average wage, with management of companies and enterprises paying the next highest.

Water plant operators are vital in ensuring communities have access to safe water. All states require that they be certified. They may be able to enter this field with a high school diploma, but will need extensive work experience and passing exam scores to advance in the certification levels.
