Wastewater Treatment Plant Operators and Technicians

Wastewater treatment plant operators control, monitor, and maintain the equipment and treatment processes in wastewater (sewage) treatment plants. They remove or neutralize the chemicals, solid materials, and organisms in wastewater so that the water is not polluted when it is returned to the environment. There are approximately 113,400 water and liquid waste treatment plant operators currently working in the United States.

Wastewater treatment plant technicians work under the supervision of wastewater treatment plant operators. Technicians take samples and monitor treatment to ensure treated water is safe for its intended use. Depending on the level of treatment, water is used for human consumption or for nonconsumptive purposes, such as field irrigation or discharge into natural water sources. Some technicians also work in labs, where they collect and analyze water samples and maintain lab equipment.
