DISTINGUISHING CHARACTERISTICS

Assignments vary from routine to difficult and, at times, require sound judgment. Work assignments for incumbents at the Operator I level with a Grade I Water Distribution certificate are normally designed to provide developmental experience in the full range of the Operator's duties. Incumbents typically follow prescribed and standardized procedures and refer unusual problems or questions to a senior operator, supervisor, or designated operator in charge.
