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