What does a green mark out line mean?

• A. Sewage
• B. Water
• C. Reclaimed Water
• D. Temporary Survey Markings

Answer: (A)

Green mark-out lines indicate sewer and drainage utilities. This color is used to warn that underground sewer mains or sewer laterals are present, so digging or other earthwork should not disturb that area without proper coordination and protective measures. It helps distinguish from other utilities: blue for potable water, purple for reclaimed water, and pink for temporary survey markings. When you encounter green, treat it as a sewer line and verify exact location with the utility owner (and follow 811 procedures) before any excavation.
