Call 811 Before You Dig is the primary key in preventing damages!
Just CLICK OR CALL 811, wait the required two business days for facility owners to mark their facilities, respect and maintain the marks, and then dig with care to avoid damage. The service is provided free to the excavator and Washington law requires that underground utilities be located prior to 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 comply with Washington's Dig Law, RCW 19.122, and begin the locating and marking process, call 811 or click callbeforeyoudig.org at least two business days before you dig (excluding Saturday, Sunday, and legal holidays).
