One Call

One-Call

Williams actively supports the nationwide One-Call system. Using One-Call prevents accidents and saves lives.

Call your state One-Call before you dig. It's the right thing to do, and it's the law. The call and the marking services are free.

How One-Call Works

Call your state One-Call center by dialing 811 from anywhere in the country. Your call will be routed to your local One Call Center. Depending on where you live, you may be required to provide a two- or three-day notice before you begin excavation.
The One-Call center will notify local utilities and companies who operate underground facilities about your project.
These companies take the information provided by the One-Call agency to determine if your project is near their operations.
If your project is close to underground facilities, the affected utility or company will send a representative to your work site to clearly mark the route and location of their operations.
