Before You Dig

​Call 811 before every digging job to have the underground utility lines marked for free. Whether you are a homeowner or a professional contractor, be smart and call 811 before each job.

Each color marking represents a utility type:

RED Electric
ORANGE Communications: Phone, Cable TV
BLUE Potable Water
GREEN Sewer/Drainage
YELLOW Gas or Petroleum Pipe Line
PURPLE Reclaimed Water
WHITE Premark Site of intended excavation


The depth of utility lines vary and there may be multiple utility lines in a common area.

Homeowners often decide they don't need to call before digging, but every digging job requires a call – even small projects like planting trees and shrubs. 

Digging without calling can disrupt service to an entire neighborhood, cause injuries and could potentially result in fines and repair costs.
