What Would I Do?

Water and Liquid Waste Treatment Plant and System Operators* operate and maintain the pumps and motors that move water and wastewater through physical, mechanical, biological, and chemical treatment systems. They monitor the indicators, read meters and gauges, and make adjustments as necessary to make sure that plant equipment is working properly. They take samples and run tests to determine the quality of the water being produced.

Both tap water and wastewater are highly regulated by the U.S. Environmental Protection Agency and other State and local agencies. Plant Operators must be familiar and comply with these regulations. Keeping proper records of compliance and documentation is another responsibility of Operators.

Water and Wastewater Treatment Operators work indoors and outdoors. They may be exposed to noise from machinery and unpleasant odors. Work is often physically demanding and performed in unclean locations. Operators must pay close attention to safety procedures because of the presence of hazardous conditions, such as slippery walkways, dangerous gases and chemicals, and malfunctioning equipment.

Treatment plants operate 24 hours a day, 7 days a week. Operators in small plants may work during the day and be on call during the evening, nights, and weekends. Medium and large plants that require constant monitoring may employ workers in three 8-hour shifts. Because larger plants require constant monitoring, weekend and holiday work is generally required. Operators may often be required to work overtime.
