Main Lines
Main Lines are the primary pipes in an irrigation system that carry water from the water source to different areas of a field or property. Think of them like the main highways of water distribution - they're the largest pipes that branch out into smaller lines to water different zones. When someone mentions Main Lines in their resume, they're typically talking about installing, maintaining, or repairing these crucial components of irrigation systems. They might also be called "mainlines," "primary lines," or "irrigation mains."
