In the context of utility markings, green is designated to indicate sewer services. This color coding system is crucial for construction and excavation activities, as it helps workers identify the types of underground utilities in a specific area, thereby enhancing safety and reducing the risk of accidentally damaging critical infrastructure.

Understanding the color coding for utility markings is essential for anyone involved in construction, maintenance, or any activity that requires digging into the ground. Green specifically signifies the presence of sanitary and storm sewer lines. Recognizing this helps workers take the necessary precautions when planning and executing excavation tasks, as disturbances to sewer lines can lead to significant public health hazards, environmental issues, and costly repair efforts.
