What do green street markings signify?

Green street markings are typically used to signify the presence of sewers and drain lines. This color coding helps ensure that those involved in excavation or construction work can easily identify the type of utilities that are present underground, thereby avoiding potential damage during operations. Knowing where sewer and drain lines are located is critical for maintaining public safety and preventing service disruptions.

While other colors are used to denote various types of utilities – such as blue for potable water and yellow for gas, oil, steam, and petroleum – green specifically points to sewer systems. This standardization helps workers identify and navigate around different utilities efficiently and safely.
