Water treatment plant 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 operators run the equipment, control the processes and monitor the plants that treat water to make it safe to drink. They read instruments and gauges to make sure processes are working properly, take samples and run tests to determine the quality of the water being produced and at times may adjust the amount of chemicals being added to the water.
Wastewater treatment plant operators remove pollutants from domestic or industrial waste.
Used water, also known as wastewater, is treated and either returned to streams, rivers and oceans, or used for irrigation. Operators operate equipment to purify and clarify the water or dispose of sewage. They clean and maintain equipment, tanks, filter beds and other work areas.
Water distribution operators maintain and operate water distribution systems.
A water distribution system is an elaborate conveyance system with pumps that allow water to move through the system and valves that allow water pressure and flow direction to be regulated.  An operator is responsible for the maintenance of water mains, water services, fire hydrants, water valves and backflow devices located within a service area.
Wastewater collection operators maintain and repair wastewater collection systems. 
Operators ensure public health and safety by preventing and/or responding to sewage overflows and blockages. They inspect, clean, maintain, construct and repair the wastewater collection systems including sanitary sewers, storm drains, pump stations, pipes, manholes and catch basins.
