Whether you're planning to plant a tree, build a deck or put in fence posts – call 811 two business days before you dig. Local One Call Center personnel will notify member utilities, such as Washington Gas, to mark the approximate locations of underground utility lines with high-visibility safety paint and/or flags.
Dialing 811 can help avoid serious injury and even fatalities, as well as property damage and significant expenses that can occur when underground utilities are damaged.
Always contact 811 before you dig.
