Career summary

Water treatment plant operators treat water so that it is safe to drink. Wastewater treatment plant operators remove pollutants from wastewater so it is safe to return to the environment.

Water treatment plant operators control equipment that removes or destroys chemicals, bacteria, or other harmful materials in water. They also operate pumps and valves that move water or wastewater through the treatment processes.

Plant operators read and adjust meters and gauges to make sure the plant equipment is working properly. They may make minor repairs to pumps, valves, and other equipment, using hand and power tools.

Operators run devices that feed chemicals into the water to treat it. They take samples of the water and analyze them in the lab. If necessary, they adjust the amount of chemicals, such as chlorine, in the water. They use a variety of instruments to sample and test water quality.

The specific duties of plant operators depend on the type and size of the plant. In smaller plants, one operator may control all the machinery, run tests, keep records, and do repairs. In larger plants with many employees, operators may control only one process. The staff may also include chemists, engineers, lab technicians, and mechanics.

Sometimes operators must work under emergency conditions. In these cases, operators use special safety equipment and procedures to protect the public health as well as the plant. They may work under pressure to correct the problem quickly.

Operators must be familiar with water pollution laws, and know how they affect their plant. They must also be aware of local and state guidelines.

Training

To work as a water treatment plant operator, you typically need to:

Education after high school

Some water treatment plant operators complete a formal training program. Professional-technical schools and two-year colleges offer programs in water quality. In this type of program you learn the basics of water and liquid waste treatment. Training programs offer a certificate or associate degree.

On-the-job training

Most water treatment plant operators learn their skills on the job from an experienced worker. Even if you complete a formal training program, you also need to complete on-the-job training. As a trainee, you begin by recording meter readings and testing water samples. As you gain experience, you learn to maintain and repair pumps and valves. You also learn safety procedures. Training may last up to two years.

The Environmental Protection Agency (EPA) recently set minimum standards for certification of drinking water treatment plant operators. Most state drinking water and water pollution control agencies offer training courses to improve your skills and knowledge.

Military training

Some branches of the military train people to be water and sewage treatment plant operators. Training lasts eight to ten weeks, depending on your specialty. Additional training occurs on the job.

Helpful high school courses

You should take a general high school curriculum that meets the state's graduation requirements. You will be required to take both math and science classes to graduate. Try to take as many Chemistry classes as you can.

Helpful electives to take in high school that prepare you for this career include:

The courses listed above are meant to help you create your high school plan. If you have not already done so, talk to a school counselor or parent about the courses you are considering taking.

You should also check with a teacher or counselor to see if work-based learning opportunities are available in your school and community. These might include field trips, job shadowing, internships, and actual work experience. The goal of these activities is to help you connect your school experiences with real-life work.

Join some groups, try some hobbies, or volunteer with an organization that interests you. By participating in activities you can have fun, make new friends, and learn about yourself. Maybe one of them will help direct you to a future career. Here are examples of activities and groups that may be available in your high school or community.

Things to know

Most employers require plant operators to have at least a high school diploma or equivalent. Most prefer applicants who are competent in math, chemistry, and biology. Formal training may increase an applicant's chances of being hired. Employers look for applicants who have completed an associate degree or one-year certificate in water quality and wastewater treatment technology.

Some positions, especially in larger cities and towns, are covered by civil service regulations. Applicants for these jobs may be required to pass a written exam. This exam tests basic math skills, mechanical aptitude, and general intelligence.

Operators must understand biological, physical, and chemical characteristics of wastewater. Experience reading and interpreting government regulations is useful. A background or familiarity with motors, pumps, and electronics is helpful. Employers may also look for candidates who are interested in learning and who get along well with others. A valid Washington driver's license or Commercial Driver's License (CDL) may be required for some jobs.

Tips

Those willing to volunteer or work less desirable shifts, and work in smaller communities or outside Washington, may have better employment prospects. Technical training that includes hands-on experience is helpful. A bachelor of science degree with coursework in microbiology, environmental science, biology, chemistry, geology, and geography can be helpful. Experience working in a related field, such as with a contractor or in a large mobile home park, may also be helpful.

Maintain a balance between classroom/book knowledge and experience. Enhance your technical skills. Become fluent in the use of the most common types of software.

For entry into the field, the following is recommended: one year of formal education in waste water technology, certification as a wastewater treatment plant operator in training by the Washington Department of Ecology, current first-aid/CPR certification, current flagging certification, and traffic control certification. For advancement in the field, work in a number of different positions and facilities, especially those with a variety of wastewater treatment methods. Use continuing education to advance your knowledge and obtain higher degrees.

Costs to workers

Some workers are required to join a union and pay an initiation fee and monthly dues.

#Took over national content to delete comments that basic computer skills are usually needed. Seems like a general job requirement now, 2/28/17 cj.

Licensing/certification

Certification by the State of Washington is required. The level of certification depends on the size and classification of the treatment plant. To become certified, appropriate education or training, work experience, and passing a written examination are necessary. Continuing education is required for the certificate renewal.

National employment

Major employers:

National outlook

Demand for this occupation will decline. As water and wastewater treatment plants become more advanced with automated systems to manage treatment processes, fewer workers may be needed. However, plants will still need skilled workers to operate increasingly complex controls.

While this occupation has a low turnover rate, it also has a low number of applicants for jobs. Thus, qualified applicants should have good job prospects.
