Public utility managers audit operations to ensure that they provide utilities to residents and businesses at the lowest possible cost. As a utilities manager, you oversee facilities that provide necessary services to residents in a city, town, or region, such as water treatment facilities, electrical plants, and telecommunications organizations. Your duties include managing water, sewer, or power systems. You ensure that infrastructure is up-to-date, inspect facilities, and order maintenance and repairs if necessary. Your responsibilities also include coordinating with response teams in the event of an unplanned shutdown and looking for ways to lower costs or improve service quality.
