In Hawaii you should always call before you dig!

Hawaii One Call Center

305 N.E. 102nd Avenue, Suite 300, Portland, OR 97220


The One Call Center system will provide advanced warning to excavators of the location of underground lines before they begin digging. This mandatory "Call Before You Dig" program will provide excavators with a single phone number to call for locating and marking underground lines, including lines for electric, gas, telecommunications, cable, water and sewer facilities.

The One-Call System does not mark utilities. The One-Call system only notifies participating member utilities. These participating member utilities will not mark private or non-member utilities. The utility locating companies notified will locate and mark only primary public utilities, so it's up to you to keep track of what else is on your own property.

Private Utilities are the buried lines after the meter or main lines. If you have a curbside meter then your property will not get marked by the participating member utility locators. Other buried utilities that generally are not marked include but may not be limited to: sewer lines, private lighting, sprinklers, fire mains, secondary electric lines to detached garages, and septic lines.
