Public utilities are the owner or operator of underground facilities for furnishing electric, gas, telephone, communications, pipeline, sewage, water, community television antenna, steam, traffic signal, fire signal or similar service, including a municipal or other public owner or operator. A public utility does not include the owner of facilities for utility service solely for such owner's private residence.


The most important first step! Always contact CBYD before work begins so underground utilities are located and marked. Smart, safe digging is no accident.
