What Water and Wastewater Treatment Plant and System Operators Do All Day

Water and wastewater treatment plant and system operators manage a system of machines, often through the use of control boards, to transfer or treat water or wastewater.

Duties

Water and wastewater treatment plant and system operators typically do the following:

  • Add chemicals, such as ammonia or chlorine, to disinfect water or other liquids
  • Inspect equipment on a regular basis
  • Monitor operating conditions, meters, and gauges
  • Collect and test water and sewage samples
  • Record meter and gauge readings and operational data
  • Document and report test results to regulatory agencies
  • Operate equipment to purify and clarify water or to process or dispose of sewage
  • Clean and maintain equipment, tanks, filter beds, and other work areas
  • Follow U.S. Environmental Protection Agency (EPA) regulations
  • Ensure safety standards are met

It takes many steps to get water from natural sources—reservoirs, streams, and groundwater—into people’s houses. Similarly, it is a complicated process to convert the wastewater from drains and sewers into a form that is safe to release into the environment.

The specific duties of plant operators depend on the type and size of the plant. In a small plant, one operator may be responsible for maintaining all of the systems. In large plants, multiple operators work the same shifts and are more specialized in their duties, often relying on computerized systems to help them monitor plant processes.

Water and wastewater treatment plant and system operators must be able to manually operate the equipment if there is a plant malfunction due to power outages or electrical issues.

Water treatment plant and system operators work in water treatment plants. Fresh water is pumped from wells, rivers, streams, or reservoirs to water treatment plants, where it is treated and distributed to customers. Water treatment plant and system operators run the equipment, control the processes, and monitor the plants that treat water to make it safe to drink.

Wastewater treatment plant and system operators remove pollutants from domestic and industrial waste. Used water, also known as wastewater, travels through sewer pipes to treatment plants where it is treated and either returned to streams, rivers, and oceans, or used for irrigation.

Local government, excluding education and hospitals 77%
Utilities 12
Manufacturing 4

Water and wastewater treatment plant and system operators work both indoors and outdoors. Their work is physically demanding and usually is performed in locations that are unclean or difficult to access. Operators may be exposed to noise from machinery and are often exposed to unpleasant odors.

Injuries and Illnesses

Water and waste treatment plant and system operators have a higher rate of injuries and illnesses than the national average. They must pay close attention to safety procedures because of hazardous conditions, such as slippery walkways, the presence of dangerous gases, and malfunctioning equipment.

Operators are trained in emergency management procedures and use safety equipment to protect their health, as well as that of the public.

Work Schedules

Water and waste treatment plant and system operators typically work full time. Plants operate 24 hours a day, 7 days a week. In small plants, operators are likely to work during the day and be on call nights and weekends. In medium- and large-size plants that require constant monitoring, operators work in shifts to control the plant at all hours.

How To Become a Water or Wastewater Treatment Plant and System Operator

Water and wastewater treatment plant and system operators typically need at least a high school diploma or equivalent and a license to work. They also complete on-the-job training.

Education

Water and wastewater treatment plant and system operators typically need a high school diploma or equivalent to become operators. Employers may prefer applicants who have completed a certificate, an associate’s, or a bachelor’s degree program in a related field such as environmental science or wastewater treatment technology.

Training

Water and wastewater treatment plant and system operators need long-term on-the-job training to become fully qualified. Water and wastewater treatment is a complex process. Trainees learn their skills on the job under the direction of an experienced operator. The trainees learn by observing and doing routine tasks, such as recording meter readings, taking samples of wastewater and sludge, and performing simple maintenance and repair work on plant equipment. They also learn about industrial safety and how to use personal protective equipment.

Larger treatment plants usually combine this on-the-job training with formal classroom or self-paced study programs. As plants get larger and more complicated, operators need more skills before they are allowed to work without supervision.

Licenses, Certifications, and Registrations

Water and wastewater treatment plant and system operators must be licensed by the state in which they work. Requirements and standards vary widely depending on the state.

State licenses typically have multiple levels, which indicate the operator’s experience and training. Although some states will honor licenses from other states, operators who move from one state to another may need to take a new set of exams to become licensed in their new state.

Advancement

Most states have multiple levels of licenses for water and wastewater treatment plant and system operators. Each increase in license level allows the operator to perform more complicated processes without supervision.

At the largest plants, operators who have the highest license level work as shift supervisors and may be in charge of large teams of operators.

Important Qualities

Analytical skills. Water and wastewater treatment plant and system operators must conduct tests and inspections on water or wastewater and evaluate the results.

Detail oriented. Water and wastewater treatment plant and system operators must monitor machinery, gauges, dials, and controls to ensure everything is operating properly. Because tap water and wastewater are highly regulated by the U.S. Environmental Protection Agency, operators must be careful and thorough in completing these tasks.

Math skills. Water and wastewater treatment plant and system operators must have the ability to apply data to formulas that determine treatment requirements, flow levels, and concentration levels.

Mechanical skills. Water and wastewater treatment plant and system operators must know how to work with machines and use tools. They must be familiar with how to operate, repair, and maintain equipment.
