What is the purpose of paint markings by a One Call System?

The purpose of paint markings by a One Call System is to indicate different types of underground installations. This system is crucial for preventing accidental damage during construction or excavation activities. When utilities are buried underground, it is vital for operators to know where these lines are located to avoid disruptions of service and to ensure safety. The paint markings utilize specific colors to represent various types of utilities, such as water, sewer, electricity, gas, and telecommunications, enabling workers to identify what lies beneath the surface before digging. This helps in planning and executing construction projects without the risk of hitting a utility line, thus minimizing the hazards associated with underground installations.
