Call Before You Dig

811. Know what's below. Call before you dig.

Washington State law requires you to notify all utility providers before you undertake any project that involves digging. Call 811 at least 2 business days before you dig, and we will mark the location of all known underground power and water lines in the area where you intend to dig. Colors for lines are as follows: Red for electric, blue for water, orange for telephone/TV-cable, yellow for gas and green for wastewater.
