In excavation processes, green markings are used to indicate sewers and drain lines. When utility companies and contractors mark the ground before excavation, they employ a color-coded system to ensure safety and efficiency. Green specifically designates the location of sewer and drain infrastructure, which is crucial for preventing potential damage to these lines during excavation activities. Recognizing these markings is essential for construction inspectors to minimize hazards and ensure compliance with safety protocols. Properly identifying and respecting these delineations helps prevent costly interruptions to utility services and reduces the risk of accidents on-site.
