Flags in the GroundA Brief Explanation of Colored Utility Flags

I’m sure you’ve noticed the small flags planted in the ground before construction projects begin. But what do they mean? Why are they different colors? And should they ever be moved? Read on to find out! (Spoiler alert: they should not be moved)

The Significance of Utility Flags

Utility flags are used to mark the location of underground utilities, such as gas lines, water pipes, electrical cables, and telecommunications lines. These markers are vital for preventing accidental damage during digging and excavation, which can lead to costly repairs, service disruptions, and even serious injuries. Each color represents a different type of utility, and knowing what they signify can help you navigate construction zones safely.

What Do the Colors Mean?

The colors of utility flags are standardized to indicate specific types of underground utilities. Here's a breakdown of what each color represents:

  • Red: Electrical lines, cables, conduit, and lighting cables. Red flags indicate the presence of high-voltage wires and are essential to preventing electrical hazards.
  • Yellow: Gas, oil, steam, petroleum, or other gaseous materials. Yellow flags mark the locations of gas lines, which can be extremely dangerous if damaged.
  • Orange: Communication, alarm or signal lines, cables, or conduit. This includes telephone lines, cable TV, and high-speed internet cables.
  • Blue: Potable (drinkable) water. Blue flags denote water lines that supply safe drinking water.
  • Green: Sewer and drain lines. Green flags indicate the presence of sewer and storm drainage systems.
  • Purple: Reclaimed water, irrigation, and slurry lines. Purple flags are used for lines that carry reclaimed or recycled water.
  • White: Proposed excavation sites. White flags mark areas where excavation is planned, signaling that digging will occur there soon.
  • Pink: Temporary survey markings. Pink flags are often used for survey purposes to mark temporary reference points.

Why You Shouldn't Move or Remove Utility Flags

While it might be tempting to remove or move these flags for aesthetic reasons or to mow or clear a path, it's essential not to disturb them. Here’s why:

  • Safety Concerns: Moving flags can lead to accidental damage to underground utilities, resulting in hazardous situations such as gas leaks, electrical shocks, or flooding.
  • Regulatory Compliance: Removing or tampering with utility flags can result in legal penalties. Regulations require these markers to remain in place until the construction project is completed.
  • Service Disruptions: Disturbing utility flags can cause significant disruptions to essential services, affecting not only your business but also neighboring properties.
  • Increased Costs: Damage to underground utilities can lead to expensive repairs and project delays, driving up costs for your business.
