They also monitor gauges and meters and record the data collected.

Typical hours

The typical work hours for a wastewater operator can be from 9 AM to 5 PM, Monday through Friday. However, wastewater plants operate 24 hours a day, seven days a week. At smaller plants, wastewater operators are likely to work during the day and be on call during nights and weekends. At medium and large-sized plants, that require constant monitoring, operators work in shifts to control the facility at all hours.
