Why do I need a wastewater treatment operator license?
The law requires it. ( 30 TAC 30.331 )
Each category of facility must be operated for a minimum of five days per week by the licensed chief operator or an operator holding a license at the required level or higher; this operator must be available by telephone or pager seven days per week. The minimum license level for the chief operator depends on the category of the wastewater treatment facility.
The amount of time to be spent at the plant each day is not specified in the rules.
Further, each person engaged in the direct supervision of domestic wastewater collection system operation or maintenance crews is required to be either a licensed wastewater collection system operator or a licensed wastewater treatment plant operator. At least one collection supervisor must hold a license class equal to or higher than is required for that category of collection system.
MGD = Million gallons per day

1 A wastewater treatment facility having a combination of treatment processes that are in different categories will be assigned the higher category. 2 The executive director may increase the treatment-facility category for facilities that include unusually complex processes or present unusual operation or maintenance conditions. 3 Where shift operation is necessary, each shift that does not have the on-site supervision of the chief operator must be supervised by an operator in responsible charge who is licensed at not less than one level below the category of the facility. 4 Category D wastewater treatment facilities will be reclassified as Category C facilities if any of the following conditions exist:
