Washington Utilities and Transportation Commission
Call 811 Before You Dig!
Be safe and always CLICK OR CALL 811. The service is free and Washington law requires everyone to locate underground utilities before digging. If an underground utility is hit while digging, it can cause serious injuries, lead to utility outages that disrupt service to entire neighborhoods, and can potentially result in fines and costly repairs.
To avoid a potential accident caused by excavation, have the location of all underground utility lines marked before excavating by hand or with equipment. To comply with Washington's Dig Law, RCW 19.122 and begin the locating a and marking process, a person must call 811 or click callbeforeyoudig.org at least two business days before you dig (excluding Saturday, Sunday, and legal holidays).
