What color flagging is used by Digsafe to mark sewer lines?

Green flagging is used by Digsafe to designate sewer lines. This color coding is part of a standardized system to help individuals identify different types of underground utilities quickly and easily.

In the context of utility marking, each color corresponds to specific types of services: for instance, blue typically represents potable water; red is utilized for electric power lines; and yellow signifies gas lines. Thus, green exclusively indicates sewer lines. Understanding this color coding is crucial for safely conducting excavation or dig work, as it helps prevent accidental damage to existing utilities and enhances overall safety during such operations.
