Have you ever wondered about the colorful markings you see all over our streets and sidewalks? Here’s how you crack the code to understand what they mean.

PL — plastic
ST — steel
Any number before a ” is inches diameter of the pipe. This will apply mostly to gas (yellow), but can apply to water as well.
