Know what’s below!

New York 811 reminds homeowners to “Call Before You Dig” to prevent damage to underground facilities and promote safe excavation, for both workers and homeowners. 

Calling before you dig helps keep your family and community safe. Homeowners should contact New York 811, by dialing 811, at least 48 hours but no more than 10 working days (excluding weekends and legal holidays) before beginning any digging project. Check out our fact sheet and process overview for more information.

New York American Water participates in and supports the 811 program, and reminds customers to “Know what’s below. Call before you dig.” For more information, visit the New York 811 website.


It’s important to call before starting any type of work involving digging. Examples include:

  • Landscaping
  • Digging holes for fence posts or a mailbox
  • Anchoring supports for decks and swings sets
  • Planting trees
  • Removing tree roots
  • Driving landscaping stakes into the ground
  • Installing a retainer wall

Calling New York 811 is the only way to determine the exact location of a utility line or underground structure.

By not calling, you risk:

  • Costly property or environmental damage
  • Explosion or fire on your property
  • Power or utilities services interruptions
  • Injury—or even death

Remember, even if your digging project is small, it’s always best to call!
