A pipelayer uses specialized equipment to assemble and connect pipes. As a pipelayer, your job duties include using ditch digging equipment to create pipe systems for water utilities, sewers, storm drainage, or other types of infrastructure. To become a pipelayer, you can complete a program at a vocational school or acquire an apprenticeship with a professional pipelayer, though many employers provide on-the-job-training. Because this job involves vital infrastructure, training can last for several years.
